This was a strange card, using several IO chips to enable it to mimic several other disk controllers. It could handle a mix of 3″, 3.5″, 5.25″, and 8″ floppy drives as well as a SASI Winchester interface.Additionally a Z80 SIO provided two serial ports with a Z80 CTC providing programmable baud rates. One serial port was standard RS232 and the other was set up for (the then proposed standard) for RS-485 high speed multi-drop.

As with other MAP products, the MPI was available ready built or as a kit with options.

(Most of the above info from a review by P. D. Coker in Scorpio magazine)

I currently have little information on this board. Can anyone help?
