Yes, well, I saw it this way: It's an unexpandable A500 in a box, stuck with 1.3 Kickstart... what is it really worth to me? I asked myself this next, would Commodore be as stupid to invent their own CD drive interface outside of IDE and SCSI? (REALLLLLY stupid question, but I gave them a glimmer of hope that they possessed common sense at some point.)
It had as many pins as an IDE cable, so I swapped out their cable with a standard IDE cable with two ports. It refused to work if any other device was attached, whether it's a slave or master.
At this point I realized that it was a futile experiment, and screwed everything back together, made a final test and everything was normal again.
The only reason why I've been concerned for its health is I brought it to my bands practice room to run sample off it. I kept gettting problems loading of the floppy, but it turns out it was just those crappy easy-die-now 3.5" floppies...
Exit!
Oh, one other thought is maybe it *is* a very limited IDE controller, which only accepts PIO 0 or something...
