The machine has a Multibus FD controller with its own
8085 CPU and a
uPD765, connected to a Toshiba 5.25" DD floppy drive (720 kB, 80
tracks, 9 sectors of 512 bytes), the model identifier is DDF5-30C-34I
... I couldn't find any information on that drive online, so I hesitate
to simply connect a more modern drive due to possible pinout differences.
...
I also found out a bit more on the SMD disk controller. It seems to be
an OEM variant of the Micro Computer Technology MCT-4300 controller.
The only place I could find this mentioned was in a catalog of Multibus
boards on archive.org.
...
So, if you happen to have any information on the Codata floppy
controller, the Toshiba floppy or the MCT-4300 SMD disk controller, I
would be happy to hear from you...
I don't, but can I suggest the Classic Computers mailing list:
http://www.classiccmp.org/mailman/listinfo/cctalk
They seem to have an extremely deep well of knowledge, and perhaps someone
there can help? (I'd rate the odds very high on the floppy drive.)
