Not sure if anyone in the Melbourne (Victoria, Australia) might be interested

Hi everyone,

Should have left it the way it was and have people set the Drive Select
themselves.
Radio Shack used a different approach to drive select by cable instead
of making use of the well documented drive select on the drive.
Radio shack jumpered all drive selects on on the drive, and pulled
pins in the
Should be fun.
Is the FDC a 765 variant?
or a WD 179x variant?

Something else we lost with the PC.
That's a 765 variant. Made by several companies, even WD!

I have a operational P112 with 3.5" floppies, GIDE/CF and CD-ROM. Do you know
which ROM you have installed?

The cpmtools has a diskdef for the p112 formats. One could therefore
copy from images to actual floppies, assuming the needed hardware can be
coaxed into connectivity with a supported os.
I do have to admit that I find it hard to believe that the cable to the
floppy can actually make a difference.
A minor point, . . .
On 5150/5160/5170, the SECOND drive is a straight cable, FIRST drive
is crossed. Thus, drive A: is at the end of the cable, B: is in the
middle of the cable.

I have it booting on a floppy. I have confirmed that you can,

Some more data points.
I have tried four different floppy cables and 6 different floppy

I had one combination where it actually booted the P112/GIDE

I have a P112 (bought as a kit) which I have assembled and plyed with a bit.
Your description doesn't mention it, so we need more details:
- did you build the P112 yourself, or did it come pre-assembled?
- has it been working before? Or is this your first time trying it?
- which version of the ROM
