Not sure if anyone in the Melbourne (Victoria, Australia) might be interested in this. I only just found about it from a friend of mine in Melbourne. The very famous (well famous here anyway) Kerleys Auction (http://www.kerleys.net.au) in Geelong have listed an Amust Executive computer in

Re: P112

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

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

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. On

Success!!!   Up to a point. I have it booting on a floppy.  I have confirmed that you can, apparently, not make disk images with an external USB Floppy drive. I am going to go back now and retest a bunch of the floppy drives and cables to see if there really is a problem or if it was just the

Some more data points. I have tried four different floppy cables and 6 different floppy drives (different brands, as well). I  had one combination where it actually booted the P112/GIDE floppy.  Got sector read errors.  But wait, it gets better.  I rebooted about a half dozen times.  The
