MultiMac cards
Below you can see the MultiMac card in HMD technique. This card type has been popular in the past, but is now almost completely vanished due to the more popular Pic cards and AVR cards. The card offers a good amount of memory and a reasonably fast processor though. The card shown here uses a 16C622 processor and a 24C64 eeprom.
I don't know of any files for this card type anymore.
