Computer Specifications

CPU and Memory

CPU (on card) 486SX/25 card: Intel 486SX, 25 MHz

microprocessor soldered on CPU card;
additional socket for optional Intel
ODP486SX/25 OverDrive module to
double internal clock speed (50 MHz);
OverDrive module cannot be installed if
487SX/25 microprocessor chip is installed
in shared socket

486DX/33 card: Intel 486DX, 33 MHz
microprocessor socketed on CPU card;
additional socket for optional Intel
ODP486DX/33 OverDrive module to
double internal clock speed (66 MHz)

486DX2/66 card: Intel 486DX2,66 MHz
microprocessor socketed on CPU card;
additional socket for optional (future)
Intel OverDrive module

Clock/calendar

High, low, and automatic speeds available;
high speed is CPU dependent, low speed
is simulated 8 MHz speed, automatic
speed switches from high to low only for
diskette drive access; speed selection
through SETUP, keyboard command, or
ESPEED program; 0 wait state memory
access at high speed

4MB RAM standard soldered on main
system board; expandable using 1MB,
4MB, 16MB, or 64MB SIMMs to 128MB
(maximum); SIMMs must be 36-bit,
fast-page mode type with 70 ns (or faster)
access speed

128KB system BIOS ROM and SETUP code
located in FLASH memory device on CPU
card; 64KB boot ROM contained in
EPROM on main system board

1MB VRAM on main system board;
additional 1MB VRAM on optional
enhanced video daughterboard (2MB
VRAM maximum)

Automatic shadowing of system and VGA

BIOS ROM into RAM; shadow RAM
address control selectable through SETUP

8KB of internal cache (built into the
microprocessor); cache testing and address
control selectable through SETUP

Epson proprietary VirtualCache feature
automatically creates a “virtual cache”
buffer the size of maximum system
memory

486SX/25 card: socket for optional Intel
487SX, 25 MHz microprocessor chip with
built-in math coprocessor; microprocessor

chip cannot be installed if OverDrive

module is installed in shared socket

486DX/33 card: math coprocessor built

into the 486DX microprocessor; additional

socket for optional Weitek 4167, 33 MHz

math coprocessor

486DX2/66 card: math coprocessor built

into the 486DX2 microprocessor;
additional socket for optional Weitek 4167,

33 MHz math coprocessor

Real-time clock, calendar, and CMOS

RAM socketed on main system board;
separate battery backup
