USING THE TAVA PC WITH A PRINTER

The TAVA Personal Computer in the basic configura-

tion provides you with one parallel Input/Output

(I/O) port and two serial I/0 ports

DOS assigns an I/0 port to a printer printer is then selected as the device on which data is printed when you enter printing commands The selected printer I/0 port is given the name

LPT1

I/0 port installed on the motherboard in the

Central Processing Unit is LPT1 an IBM Monochrome monitor adapter, there is a

parallel I/0 port installed on that board and it will be LPT1

WHAT

Troubleshooting

identifying a problem and solving it is a logical progression through a set of routines

to solve a problem with your system

will guide you through a series of questions, most

of which can be answered YES

will take you through a series of steps requiring

simple observations laid-out steps you will be able to determine if

the machine requires professional service or if

you can take corrective action yourself
