Fingers Crossed for 2021 ...

We're hoping to re-open in the next few months ... fingers crossed! Read More >>>

Aleph One PC Expansion with 4MB SIMM

This is a PC Expansion card for the A3010, A3020 and A4000 although it probably works in an A3000 as well. I have never tested the card and it is missing its backplate. The card has a Cyrix Cx486SLC-25MP CPU which runs at 25MHz has 1KB L1 cache and no FPU. The SIMM is a 4MB SIMM with 8 x 1Mx4 70ns DRAM. Unlike the full size podules, it does not have a parallel or serial port on the card. it appears to have a connector for an external power supply.

Here is the Aleph1 !PC 2.06e  software to configure and run the PC mini-podule.

Date : 1993

Manufacturer : Aleph One Ltd

Physical Description : Expansion Board 4MB SIMM

This exhibit has a reference ID of CH48020. Please quote this reference ID in any communication with the Centre for Computing History.
