This is a PC Expansion card for the A3010, A3020 and A4000 although it probably works in an A3000 as well. The card has never been tested 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.
