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. |

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