A full length Zorro II which appears to provide SCSI facilities as well as additional RAM in the form of 8 x 30pin SIMMs. It probably supports a maximum of 8MB of RAM. The card is made by Cosmos Computing, but what is it called and what are the additional functions?

It has the following connectors:


  • External 25pin connector
  • Internal 50pin connector
  • Internal 26pin connector
  • Internal 34pin connector
  • Internal 10pin connector
  • Internal 6pin connector
  • Internal 2pin connector
  • Internal 3pin connector
  • DIP switch x4
  • 28pin ROM socket x3

Caution: The 26pin connector does not appear to be a floppy drive connector. A floppy cable was used and it burnt out.


Comment: The MC146823P chip from Motorola is a parallel port chip w/24 I/O lines which would allow it to provide for 3x 8-bit paralel ports.  It's design is aimed at the 65xx/68xx era of 8-bit CPU chips' bus protocols.  There is a Z0853006 microprocessor on there. Also That may be an 80C318M 8-bit Microcontroller (Intel/Phillips).
