design. It provides the following features:
386SX, 33 MHz microprocessor
2MB or 4MB of internal memory, expandable to 16MB
System and video BIOS shadow RAM
256KB of on-board video memory, expandable to 512KB or

built-in game port
Built-in PS/2 compatible keyboard port
Three 16-bit full-length and two 8-bit half-length ISA option

The shadow RAM feature allows your system to speed up
processing by moving the system and video BIOS into the RAM
area of memory.
Using the built-in interfaces, you can connect most of your
peripheral devices directly to the computer so you do not have
to install option cards. You can use the option slots to enhance
your system with extra functions such as a modem card, a
network controller card, or additional interface ports.
