Introduction

1.1 Hardware Overview

The GTE K Model 2010 single board computer is intended to be the

best single board computer to use for control applications ever made.

The 2010 has 40 pr ogr ammabl e I/O lines . Eac h I/O lin e may be
progra mme d for e it he r in put or output w ith out r ega rd t o its pos it ion on
the connector. Eight of those 40 are POR T 1 of the processor . The other
32 are on 2 Z80 PIO chips.

In addition to those 40 I/O lines, are lines to be used to expand the
functions o f the 2010 board . AD0-AD7, ALE, RD, WR, PSEN, A8- A15,
ROM, CMM, VDD, P1.5, P1.6, P1.7, Vcc, Vdd, DTR and GROUND are
brought to a 34 pin expansion bus (see appendix A). This makes
expans ion to more memory or boards, like a D/A A /D con verte r or more
I/O, easily attached. With proper design, the board could just piggy
back on top of the 2010.

The 2010 has a built in 5 volt regulated power supply. It needs to be
connected to a s ingle ended pow er supply capable of at least 9 v olts
at 500 milliamps to b e adequately powered. If you attach exp ansion
boards to it, you must use an adequate power supply. The RS-232 uses
a MAX-232 chip to obtain the + — 12 volts for the RS-232 supply.

With the proper power supply, you can supply approximately an
other 250 to 500 milliamps to peripherals. You must provide for
ade qua te cooli ng of the re gul a tor, howe v e r . T h e r egu la tor i s ca pabl e of
delive r ing up to 1 amp provided pr oper heat s inking is prov ided.

1.3 Software Overview

Much of the software for the 2010 is strictly communications
software. That is, you could use other programs to communicate with
the 2010, but our software will recognize upload, download and other
commands and handle them a ccordingly.

Most of the commands are handled by the 2010 directly, rather than
on your computer . This allows it to run in the same way on virtually any
computer or terminal.

The software used to handle comm unic ations is called B51.COM.
A progr am called PINSTALL is pr ovided to install it for the Baud Rate
or COM port you are using. The software used to handle
upload/download from t he BAS IC opti on is called B51 .COM. U se B 51
to save/load your basic programs either in an ASCII format for imme­diat e use w ith an EEpro m, o r i n a to keni zed f orm at so t hat yo u c an
dedicate the contr oller with a BA SIC program in an Eprom.

1.4 Software Specifications

Althoug h t h e 2010 is c apabl e o f com m u n icatin g at Baud Rates of
fro m 300 to 57,600 Bau d, B51 co mmunic ates at 9600 Baud . Com­mands are available to save or load an ASCII BASIC program, and save
a tokenized BASIC program to execute from a burned Eprom.

Model 2010B Chapter 1

Page 2

1.5 Firmware Overview

Much of the versatility of the model 2010 board comes from being
able t o refr esh ram th ro ug h an in terr up t ser vic e ro uti ne every 2 mi l­liseconds. The built in monitor firmware takes care of this in conjunction
with the P AL. Y ou are not aware of this going on except that you cannot
make exclusiv e use of th e timer taking care of th i s function.

Much of the fi rmwa re mon itor is ti e d into th e PA L fu nctiona l ity. This
means that if you write code to go into the Eprom or EEprom, then you
must also include the monitor code. If you don’t you may lose function
of t he ram ref resh and o f cou rse all o f the bui lt- in c omm ands and
RS-232 communications. When using the B51 program to save
token iz e d bas ic to be put in to an E prom, you s hou ld us e t he MK E . BAT
program to put the monitor and other things into the correct location
in the Eprom.

1.6 Firmware Specifications

The firm war e inc l ud ed wit h the 8052AH BASIC c hi p t akes c ar e of
the Ram Refresh and new commands added to 8052AH BASIC. Refer
to the memory map. Locations 0-1FFFH in code memory are reserved
for 8052AH BASIC. 2000H Through 7FFFH is reserved fo r BASIC and
the firmware monitor. When using a 2864 or 2764 (8K memory device),
it i s inser ted at loc atio ns 2000H t hro ugh 3FFFH. When usi ng a 16K
devi ce, it is in serted at 2000H t hrou gh 5FFFH. When using a 32K
device, it is inserted at 2000H through 7FFFH. Note that you lose 8K to
the 8052AH BASIC monitor rom.

Getting Started

2.1 Unpacking

When unpacking the model 2010 board, be sure to watch for items
such as j umpers, d isks, cables, and instructions and/or errata sheets
while you are unpacking. Many phone calls have been made in the past,
bec ause in th e hast e of unp acking and get ting to the m ain boar d,
materia l th a t w a s th ough t to be packi n g m a te r i a l w a s pr ote cti n g a dis k
or ins tr uc t io n m anu als. These mat eri als sh o uld b e p lai nly mar ked as
"instructions" or "disk", but some people don’t take the time to read it
and discard it. If you think yo u are missing anything from your or der,
please be sure to go back through the packing material to make sure
tha t it was not acci dentally discarded.

2.2 Installation

The 2010 board (depending on the options ordered) generally
comes set up to plug in and run. Yours should be set up with the Basic
monitor on a 2864. Jumpers will be s et for this installation with no other
option ju m pers.

2.2.1 Quick Start

To begin communicating immediately with the board follow these
instructio ns:

1—Plug i n RS–232 cab le t o c o mp u ter and 2010 b o ar d . (o r mak e

cable from instructions in appendix D).

2—P lug wall trans f ormer into board.

3—Plug wall transformer into 120 Volt outlet.

4—Run B51 (B51 is an optional program) communications pro-

gram.

5—Issue commands.

Remember that if you don’t have the B51 communications program
that you will have to set the communications parameters first on your
comp uter to communicate with the board. The 2010 is set up to be a

Chapter 2 Model 2010B

Page 5

DCE device. This means that on an IBM PC or AT type computer (that
has a D TE port) the cable will run straight through.

2.2.2 Normal Installation

After u npac kin g th e 2010, set it up fo r yo ur use. Nor mally, it w ill
already be installed to use with the 8052AH BASIC. However, you may
install the board in this manner:

1—If you didn’t get a cable from us, make an RS-232 cable like this:

a) The c able requir ed is a st raight thro ugh c able. Pin 2 on the

computer hooks to pin 2 on the 2010. Hook up pins 1, 2, 3, 4, 5, 6,

7, and 20. 8052AH BASIC does not require hardware handshaking,

so you could just use pins 2, 3 and 7 for a cable.

b) The comp ut er end of the cable will require a female connector,

while the 2010 end requires a male connector.

2- Hook the RS– 232 cable to the 2010 and the computer.

3- Chec k t he j u mp er s fo r o per at io n. A no rm al fi rst ti me o p erat io n

will already have the jumpers in the correct location, however check

the jumpers as follows:

JB5

—1 is /EA of the processor pulled high by a 2K RP (for internal

progra m m emory).

—2 is G r ound (for external pr ogr am me m or y acces s)

Default: leave this jumper open for use with 8052AH BASIC. Ground

it to use the 8052AH as an 8032.

JB6

—1 is Vcc. (used for 2764/27128 /pgm pin.)

—2 is pin 27 of t h e program memory socket (common).

—3 is A14 of the Address Bus

—4 is /WR from th e processor

Default: 4–2 for 2864. Hook 1–2 for 2764,27128. Hook 4–2 for 28256

to allo w / WR to pr og ram EEpro m. H oo k 3–2 fo r 27256, 27512 to

allow A14 on pin 27 (A14).

Model 2010B Chapter 2

JB7

—1 is Vcc. (used for 2764/27128/27256 Vpp pin.)

—2 is pin 1 of the program memor y socket ( com mon)

—3 is A15 of the Address Bus

—4 is A14 of the Address Bus

Default: 4–2 for 2864. Hook 1–2 for Vcc to Vpp of 2764,27128,27256.
Hook 4–2 for 28256 to allow A14 onto pin 1 (A14). Hook 3–2 for 27512
to allow A15 onto pin 1 (A15).

27512 32K Eprom 1–2 2–3 2–3 ML

27512 24K Eprom none 2–3 2–3 BASIC

JB5 controls external access of program code fetches. If it is
jumpered /EA is grounded, forcing the processor to fetch code exter­nally fr om t he Ep r o m . If you have a 8751 o r 87C51 y o u sh o u l d l eave
pin 1 a nd 2 of JB 5 ope n (n one) to fetch code in ter nal ly fr om the Epr om.

JB6 controls where pin 27 of the program memory socket (Eprom
or EEprom) connects. Pi n 2 7 connects to pin 2 of the jumper block. If
pin 2 is jumpered to pin 1 (Vcc) then that pin is held at Vcc for a 2764.
To pin 3 will connect line A14 to pin 27 for a 27256. To pin 4 will connect
/WR to pin 27 for for /WE for 8K EEproms, Xicor X2864A for example.

JB7 contr ols whe r e pi n 1 of the progr am me mory s ocke t ( E prom or
EEprom) connects. Pin 1 of the program memory socket connects t o
pin 2 of th e jumper b lock. If pin 2 is j umpered to pin 1 (Vcc) then t hat
pin is held at Vcc for a 2764. To pin 3 will connect line A15 to pin 1 for

27512. To pi n 4 will co nnect line A14 to pin 1 for a Xicor X28256 for
examp l e.

anot her exter nal p o wer su pp ly, th e be su re th at yo u d o n’t exc eed 9
Volts input . If you do, ma k e sur e that the extra power diss ipation from
the 7805 is taken care of. A 12 volt power supply may require additional
heat sinking or forced air cooling of the heat sink of the 7805 regulator.

On the Miniature phone jack connector the tip is + and the ring is
—. There is a diod e in ser ies wit h the l ine go ing to t he reg ulat or to
prevent reverse current flow, so if the board does not operate, check
for power reve rsal.

If yo u ar e su p plyi ng a reg ul at ed + 5 volts fro m an ex t er n al pow er
supply, unsolder and remove the 7805 regulator from the board. Hook
the + 5 volts to either the expansion connector or the hole where the
output pin of the 7805 was, and the ground to either the expansion plug
or the middle leg hole of the 7805.

New Commands and Additions

3.1 NEW COMMANDS

All th ese com mands c an be exec uted ei ther fro m an exec uting
basic program or from the immediate mode. Some commands are
better executed from the immediate mode, such as for the baud rate.

In the prog rams shown below, a command that you are to type in
from the command prompter is shown in bold. A "enter" is shown as
< cr> . A > R EM is s im pl y a comm e n t tha t doe s n ot have to be ty pe d.

3.1.1 AUTOEXn

Special command t o perfor m an automatic command on boot up.

AUTOEX0

Causes an auto baud–rate seek on pow er up. You must

strike a space bar to lock onto the baud rate. (default)

AUTOEX1

Saves the current baud rate. No space will have to be

struck before any execution begins.

AUTOEX2

When executed will cause 8052AH BASIC to boot to the
READY prompter instead of loading and executing program 0.
(default)

AUTOEX3

When executed will cause 8052AH BASIC to lo ad and
exec u t e p r o gram n u m b er 0, i f there i s o n e saved by t h at n am e. If
there isn’t one, then it will return to the READY prompt.

AUTOEX4

When executed will c ause 8052AH BASIC to use our
SLOW EEprom program routine to be used for certain types of
EEproms that program slowly when using the SAVE and ERASE
commands.

AUTOEX5

When executed will c ause 8052AH BASIC to use our
FAST EEprom program routine to be used with certain types of
EEproms t hat ca n be programme d fast . (defaul t )

Onc e any of the abo ve com mand s are used, they b ecom e per­man ent in the EEprom. To change them , simply issue the opposite
command. Eg. if you have used AUTOEX1, to change it use
AUTOEX0.

1 size 988
>_

Note: The order in which you saved the programs is how they will
appear on screen. There may be up to 254 files if you had room for
them on the EEprom.

3.1.3 EGETn
EGET

Is a command that PUSHes an 8052AH BASIC 6 byte floating
point n umbe r fr om st ora ge in the E E pr om on to the a rgu me nt st ack.
You can retrieve up to 32 numbers in this fashion (0-31). The
num bers are s tored in EEpro m (o r Epro m) fro m 2740H thr oug h
27FFH (192 b y tes ). Yo u c an c reat e a f ile ex t ernal ly o n d i sk t o b e
stored on the Eprom so that you can EGETn those numbers after
power has been off or f or r e-boots.

EXAMPLES of EGET:
> PUSH 32: EPUT 0 : EGET 0: POP A: ? A< cr>
32
READY
>_

3.1.4 EPUTn
EPUTn

Is a command that POPs an 8052AH BASIC 6 byte floating
point number from the argument stack and programs the EEprom
in the storage area (2740H- 27FFH). The number may then be
obtai ned by an EGE Tn and a POP command.

EXAMPLES:
> PUSH 123.45678: EPUT0: EGET0: POP A: ? A< cr>

123.45678
READY
>_
> REM now that number is in permanent
> REM storage (until it’s changed)
> REM in the EEprom at location 0 of the EGETs.

3.1.5 ER ASEn
ERASEn

is a command that will ER ASE a program from the EEprom
program storage area. It is the opposite of SAVEn. The 2010 will
remove the program by rewriting the entire EEprom program
storage area so that there are no gaps after the program is removed
from storage. The range of n is 0–254 (0–FEh).

Examples:
> DIR< cr>

4 size 389
2 size 185
0 size 1084
1 size 988
READY
> erase0< cr>
READY
> dir< cr>

3.1.6 INn
INn

is a command that will input 8 bits of data and PUS H it onto the
arg ument s tack from the 4 ports on the Z 80- PIO ’s. The vali d num­bers for the ports are 4, 5, 6 and 7. U4 Port A is what we call port 4,
U4 Po rt B is what we call port 5, U3 Port A is port 6 and U3 port B
is por t 7. (See Appendix A for pinout)

Examples:
> IN4: POPA: ? A: IN4,5,6,7: POP A,B,C,D< cr>

255
READY
> PRINT A,B,C,D< cr>
255 255 255 255
READY
>_

3.1.7 LOADn
LOADn

is a command that will cause f ile number n to be loaded to
current Ram memory. A NEW is automatically done before the
LO AD , so files will not "merge" in memory . The range of n is 0 to 254.
If LOADn is executed on a program line, another program is L OADed
and run. You could chain programs together like this. All variables
are lost during t his process, but you can use

EPUTn, EGETn, LD@

and ST @

commands to save your variables.
Examples:
> LOAD9< cr>

READY
> REM Loads file 9 from EEprom to Ram.
> RUN: REM Run it.

Model 2010B Chapter 3

Page 12

3.1.8 OUTn
OUTn

is a command that will output 8 bits of data (to port numbers
4, 5, 6, or 7) to the Z80-PIO’s, that was POPped from the argument
stack.

Examples:
> C= 29: PUSH 22,25,32,C: OUT 4,5,6,7< cr>

> REM Port 4 pins contain data 29, Port 5 pins contain data 32
> REM Port 6 pins contain data 25, Port 7 pins contain data 22.
> IN 4,5,6,7: POP PORT7,PORT6,PORT5,PORT4< cr>
READY
> PRINT PORT4,PORT5,PORT6,PORT7< cr>
29 32 25 22
READY
> REM PORT4 etc in the above line are just variables we used.
> REM Remember that PORT1 is a Basic Keyword!

3.1.9 SA VEn
SAV En

is a command that will save the program that is currently in
Ram to t he EEprom in file number n. The range of n can be from
0–254. If th ere i s c ur ren tl y a p ro g ram res id in g i n t hat file n um b er,
then an error message will be issue d. If there is not enough memory
to save that file, then a n e rror messa ge will be iss ued.

Example:
> SAVE3< cr>

3.1.A TK O
TKO

is a command that will cause each byte of the program in
memory to be output to the console in an ASCII-HEX form. One
binary byte becomes 2 ASCII bytes. Thi s comman d is used by the
program B51 to capture the program in Tokenized form to be put
on an Epro m usin g an ex ternal Eprom Prog ram mer suc h as the
GTEK mo d el 9000. This c o mm and sh o uld no t b e issued fr o m th e
console. It should be used from the "Enter Command Line" com­mand within B51.

:

79 is number of machine cycles for refresh. 12/XTAL is period for 1
machine cycle= about 1.090909 uS. ABN is Actual Baud Number .
BR is the baud rate of the device to be output to:

or
ABN = 1 / ((1/baud) - (79*(12/XTAL))

Use the 2010 to calculate it for you:

Y ou should not use baud rates lower than 600 Baud, because since
the same timer for Ra m R e fresh is used for baud rate running at 300
baud (about 3.3 millise conds), that is longer than the time between
refresh cycles. The ram could probably withstand the rate, but a
marginal Ram chip might not make it much longer than the 2
millisecond rate specified for that c hip. See Page 28 in t he

Intel

manual. The

Intel 8052AH Basic manual

is an

optional purch ase.
b) Do not use

CALL (0-127)

unless you are using an Eprom greater

than 8K and have provided the proper vectors. use

c) T h e

PWM

statement (Page 62 of

8052AH BAS IC

manual) will run
differently, due to the Ram Refresh having higher priority. The
minimum valid numb er usable for the numb er of c lo c k c yc les the
wave will re main high or low is still 25, but since a R am R efresh C ycle
will occ ur for every transition, you must figure that there are ap­proximately 79 additional machine cycles added to the number of
ma chine cycles yo u use for the

PWM

statement.

PWM 100,100,1000

that h as a perio d of ( 100m c + 79m c)* 2 * 1.0909us = 390uS on
P1.2 (2560 HZ). It i s not possible to obtain the sam e frequ ency as
on page 62 because the number that you would use for mc would
be Machine Cycles = (217us/(2*1.0909us)) - 79 = 20, which is too
low to use in the PWM statement since 25 is the minimum. Referring
to the program on page 173, use the one following instead:

10 PRINT"1= FREQUENCY FOR PWM"
11 PRINT"2= RELOAD FOR FR EQUENCY"
12 PRINT"3= QUIT -",

Co mmunications Software

4.1 B51 Installation

On your disk you have B51.COM and PINSTALL.COM. Run

PINSTALL to ins tall B51 for the COM p ort and 9600 baud. The 2010B
should be set so that it will begin communication right awa y. If you don’t
immediately get the prompter when you run B51, type a space bar first!
This will cause the 2010B to lo ck o nt o the b au d rate. Rememb er th at
you ha ve to be se ndi ng a t the n ew baud r a te a n d re – boot the 2010B to
res et the bau d rate with a space .

When you use B51 with your 2010, remember that if you have been

usin g it at ano th er Baud Rate and have do ne an AUTOEX1 at som e
other Baud Rate than 9600, you will not be able to communicate with
the 2010 until you change it to 9600 with the other program. If you are
set with AUTOEX0 (auto baud seek) then you won’t have any problem
communicating.

4.2 Using B51

Mos t of the tim e B 5 1 is a si mple commu ni cati on progra m, un til you

execute a CONT R OL– F. At that time it will ask you to enter a command:

> ^F
Enter Command —> filename /option/option< cr>
Options for saving are /S and /T. A /S is used for saving the

"filena me" a s a n a scii file. A /T (which must always be use d with /S) will
sav e the " fil en ame " in a token ize d forma t. If you us e the /S/T option the
filen am e m us t alw ay s b e a f il en am e b y th e n am e o f TFn wher e n is 0
through 9.

An ASCII save (/S) will create a filename.B51 file on your disk. A

tokenized save (/S/T) will create a filename.TKO file on your disk. You
don’t have to specify any extension with your filename.

The reaso n you mu st use TFn for a filename wi th th e to keniz ed

format is that there is a BATCH file on your d isk called MKE.BAT.
MKE.B A T will take tokenized files and combine them with the operating

Chapter 4 Model 2010B

Page 19

system and other system files into a file called BURNME in a binary
format. This is so that you can install them in an Eprom using an E prom
Programmer such as GTEK’s Model 9000, to be used on the 2010.

Example: To load an ascii basic file with extension of .B51
>^F
Enter Command —> test< cr>
The above command will look for a file called test.B5 1 on your disk

and then issue a

NEW

command to the 2010. It will then send the as cii
file to the 2010 one line at a time, waiting for the prompter to come back
before sending any more characters at the end of a line. It is possible
that if you "saved" the file before with lines that were full (79 characters),
you will not be able to get the file back into the 2010. It will cause the
2010 to begin beeping with each character that is sent, and not accept
any more charact ers. If that is the case, you will have to edit the line
with a word processor before you can send it back, to eliminate ALL
spaces on the line. This is the typical cause of the problem if you have
previously "saved" the file in the ascii format. If you wrote it with a word
processor, you have exceded the line limit and should break the line
into two lines.

Example: To save program in ram to disk in ascii format
> ^F
Enter Command —> test /s< cr>
The above will lo ok for a file called test.B51 on the disk. If it do es

not exist, then it will cause the current program in the 2010 to be

LIS T

ed

to the disk in a file called test.B51.

Ex ample: To save program to disk in tok enized for m at
>^F
Enter Command —> tf 0 /s/t< cr>

The above will look for a file called TF0.TKO on the disk. If it does
not exist, then it will c ause the current pr ogram to be sent to t he d isk
in a "tokenized" format. You will see ascii-hex numbers being listed to
the screen du ring the process. You cannot get the TF0.TKO fil e back
into the 2010 without burning the file into an Eprom. Of course it does
not d estr oy the pr og ram that is cu rren tly in the 2010 du ring t he /s/ t
process.

Model 2010B Chapter 4

Page 20

4.3 USING MKE.BAT

After the TF0.TKO file is on the disk, if you would like to install that
progra m i nt o an E prom t o ru n a s a de dica t e d progr a m (before y ou /s / t
yo u shou ld have d one an AUTOEX1), you may issu e the MKE.BAT
command from the DOS system prompt. The line is too long to print
as 1 line, but here is MKE.BA T:

copy b9035v2.bin/b+ puts.bin/b+ xb96.bin/b+ %1.tko/b+

%2.tko/b+ %3.tko/b+ %4.tko/b+ 5.tko/b+ %6.tko/b+ %7.tko/b+

%8.tko/b+ %9.tko/b+ eofchar.bin/b burnme/b

Ex ample: To sen d data for eprom t o GTEK programmer

C> MKE TF0 TF1 TF2< cr>

The above will take the 3 tokenized basic files called TF 0 , TF1 a nd
TF2 and add th em to th e system info rm ati on fo r t he Epr om and p ut
them in a file called burnme. The above MKE file with the specified
parameters as executed by the batch file becomes:

copy b9035v2.bin/b+ puts.bin/b+ xb96.bin/b+ TF0.tko/b+

T F1.tko/b+ TF2.tko/ b+ eofch ar.bin/b burnm e/b

The burnme fi le is a bi nary fi le that then m ay be used to create an
Eprom with those 3 basic files on it. If you have AUTOEX3 in force then
the file you named TF0 will become the program that begins running
on a B OOT (appl y ing powe r or reset).

On a GTEK Model 9000 programmer this BURNME file may be sent
directly to the Eprom. On the other model GTEK programmers (7128,
7228, 7956), you must first run the program GHEX on the BURNME file
if you are not using the program PGMX7 (or PGMX), since it is a Binary
file and it should be an Intel Hex file instea d for those models running
PGX or oth e r pr ogram. O n ot her progra m me r s you s hou l d f oll ow their
procedu r es f or burnin g a binary fi le in t o an Eprom.

When you in s tall t he Eprom into the 2010 in place of t he EEpro m,
REMEMBER TO SET THE JUMPERS IN THE RIGHT POSITION! If you
don’t then som e u nexpected thin gs mi gh t h a ppe n , li ke it don’t wor k a t
all!

Model 2010B Appendix A

Page 26

refer to Port 4 (Z80–PIO U4 Port A, bits 0–7). All the bits are pulled high
by a resistor pull–up pack, and the port will have a va lue of 255 (0FFh)
when read with nothing hooked to it (when first booted). If bit 7 was
sho r t ed t o gr ound t h e data would r ead as 127 ( 07Fh) w hen r ead . An
OUT4 would cause the data from the argument stack to be output to
Port 4.

When th e 2010B d o es a Basi c "OUTn" in st r ucti o n , t he output p i ns

of the Z80–PIO are not set to output as referred to in the Z80–PIO data
sheet unless the bit datum is 0. They are always set as inputs if the bit
datum is 1. The resistor packs pull the pins to Vcc instead of the bits
being "set" to output a 1 on t h e port. This avoids con t ention problem s
where you might be mixing inputs and outputs on the same Z80–PIO
port.

This mean s that if you are driving a transist or base with one of t he

bits, fo r example, wh en you "read" the por t wit h a Basic "INn" instruc­tion, that bit will read as a 0 because the ma ximum voltage that will be
on that tran sistor base is only going to be .6 volts , which i s a TT L low.
Of course if you were to o utp ut a 0 to that b it, you wo uld cause the
transistor (NPN) to turn off. Outputting a 1 to that bit would cause the
transistor to turn on again since the base is pulled up to Vcc through
a 2.2K resistor. If you have to have a different bias level, you should use
either a darlington type transistor or cascade them.

When th e 2010B po wer s o n, all o f th e Z80–PIO po r t b i ts will b e 1

because they are all programmed for "read" on boot. None will be 0
unless you have done an "OUTn" instruction with that bit set low.

After you have don e an "OUTn" ins truction and you read that port,

you are NOT reading the output pin of a particular bit if it was set to 0.
Yo u are reading the output latch instead. Other bits that were set to 1
are still set as inputs and you are still actually reading the output PIN
and not the latch.

In the cas e of PO R T 1, which is a n 8 bit port th at come s dir ectl y from

the 8052AH chip , t h e b i t s ar e h andled as t h ey w er e com i ng fro m t h e
proces sor nor mall y. If you output a 1 on a bi t on thi s port, you a re dr ivin g
the bit high also, ev en though it also has a resistor pull–up pack .

Example Ascii Basic Program

T hi s i s an e x e rci s e i n w r iti n g a basi c progra m th a t ca n be sa v e d on
the EEprom and/or saved to the disk. We will go from writing the
program to saving it on the EEprom and then saving it on the disk.
Follow the steps in order. Commands or data that you will have to type
yourself will be in bold. A < cr> means to strike the "enter" key. A
< sp> mea ns to strike the space bar. Comments will be between two
left and right arrows (also called "greater than" and "less than" signs).

1—Communicate with the 2010B with B51 from the DOS prompter:

C> B51< cr> < sp> < in case you are us ing auto baud rate det.>

—L og on mes sage—

To save th i s progra m y ou just ty ped into ram onto t he EEprom ,

first ma ke sure that you have moved the jumper (2–4) a nd type:

> SAVE 0< cr>

> dir< cr>

0 size 1089

READY

>_

Your program is now saved on the EE prom in file # 0. If you then

type:

> autoexec3< cr>

READY

>_

This will cause the program you just entered to automatically

begin running when you apply power to the 2010. To save your

program to an ascii file on your disk (using B51), type:

> ^F

Enter Command Line — > BOOTMSG /s< cr>

READY

>_

This will cause B51 to

list

the pr ogr am in r am to a disk f ile by t he

name of

BOOTMSG.B51

. You can then load the program by

typing:

> ^F

Enter Command Line — > BOOTMSG< cr>

READY

>_

The above causes B51 to look on the disk for a file by the name

of

BOOTMSG.B51

and if found will issue a

NEW

command to the
2010B and "enter" the data in the 2010B as if you had typed it
from the keyboard. When done, control is returned to the com-

mand prompter of the 2010B. If you would like to "load" a pro­gram from the EEprom type:

> load 0< cr>

> run< cr>

The above has the following effect:
