External Cache

You can install 128KB, 256KB, or 512KB of external cache with 32K x 8, 64K x 8, or 128K x 8 15ns or 20ns, SRAM DIP chips and one 32K x 8 15ns or 20ns tag chip. The computer may already have cache installed.

You must install cache in one of the configurations in the table below (each bank contains four cache memory sockets).

*If you install SlMMs in both Bank 0 and Bank 1 or Bank 2 and Bank 3, SIMM types must match.

Use only tin-plated, 32-bit, 72-pin, fast-page mode SIMMs that operate at an access speed of 80ns or faster. Be sure all the SIMMs operate at the same speed.

Processor Upgrades

The computer’s processor can be upgraded by replacing the existing processor with a faster one. The following table lists supported processors and voltages.

Supported processors

Video Memory

The computer comes with 1MB of video memory. You can increase the video memory to 2MB by installing two 512KB, 40-pin SOJ flat pack video DRAM chips. (You cannot increase video memory by installing just one chip.)

Hard Disk Drive Types

Your computer comes with a hard disk auto-sensing feature. To use it, select one of the drives you have installed from the Fixed Disk Setup screen. On the screen that appears for that drive, press Enter to select the Autotype Fixed Disk option. The system detects the type of hard disk drive, fills in the drive’s parameters, and sets the remaining options on the screen.
