FISK – It's a floppy disk fax machine

8088 internally with a custom ASIC for the board support (no DMA). I think it launched in 1990.

Memory was 128K of Intel flash with 8K fixed boot partition and 64K of RAM.

Z8530 for the UART, Rockwell chipset for the fax portion. I seem to remember lots of messing around getting the parameters correct for the filters to detect dial tone for various european telco approvals. There was also a pass through port to allow plugging a fax machine in the back (can't remember how that worked though)

I can't remember what we used for the floppy disc controller (I seem to recall we supported single density floppies so we didn't use a multi-IO chip) and later models used a IDE drive with a 16->8 bit converter card.

Somewhere I probably still have the schematics.

Very neat! That sounds like it's pretty similar to this one then. I wonder if the FISK was directly inspired by the DiskFax? I'm hoping to get in touch with the designer so I may have some answers soon.

I'd love to see those schematics if you can find them!
