Aleph1 PC Expansion card for A30x0/A4000 (bottom)
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.
