No, nobody else inquired about it.
I have no idea it will fit a DEC backplane; AFAIK it was used on NCR
systems. It might take me a while to find it; when I do I'll try to
determine the dimensions of the pins and the wire gauge.

Pin 4 is "Head Load"
Pin 6 can be either "Ready" or drive select 4
Pin 10 is drive select for first drive.
Pin 34 is "READY", or "Disk Changed", or fourth drive selrct (TRS80)
BUT, IBM PC puts a twist in the cable (pins 10 - 16?), and does selection
by the cable with all drives jumpered to b
I'll take that offer, thanks Van!
And in general, about this experiment:

The Sharp PC-5000 was definitely MS-DOS, not PC-DOS.
PC-DOS, however might work on it! or at least almost.
BUT, some of the supplied programs will be different.
For example, MODE.COM will be significantly different.
The PC-7000 was reasonably PC compatible.
The PC-5000 was VERY similar to the G
Only related to the subject, not the body of the discussion:
I found a stack of 5.25" floppies for Norton Utilities. I don't have
any 5.25" drives. If you want the disks, they're yours for a PDF of a
shipping label for 8"x10"x1" 8oz. I have no idea whether they're
readable.

The Siemens 4004 was basically a rebadged RCA Spectra 70, so this is a
RCA 70/15. Maybe technical/service manuals for this system come up.

I will chip my 5 cents worth in here... For some reference, i have
