Isn't that one pin-compatible with one of the newer revisions of HD61480?

How about a board with a 64180, a 2797 floppy cont., 512K ram, 32K eprom,
centronics port and a NCR5380 SCSI controller?

That is the CP/M computer which I built about 5 Years ago.

Unfortunatetly it is an double extended eurocard (approx. 200*220mm),
so it wont fit in one of the SCSI slots on the pc532. But I am
thinking about a wire-wrapped half-length IB-PC-like M-PC prot board
with the same kind of processor, one 1MB-simm, boot-prom , a DP8490
SCSI interface, a DP8473 FDC and a printer port.  I can prototype
such a board if someone is willing to assist in writing software which
converts it to a SCSI floppy & printer controller.  I will also make
the small changes in my BIOS necessary to run CPM3.0 on it.  This
board will be so simple that I think anyone capable of soldering can
wire-wrap it.

And if anyone can help me getting the parts cheap the better. Because
here in Sweden components are expensive (10MHz 64180 = $45).

The board could also drive a floppy compatible tape drive. I have an
second hand IRWIN-125 with some manuals.

Happy Hacking
