x68030 internal scsi cable: Adapters?
« on: June 25, 2018, 06:09:33 AM »
A cursory scan of the internet didn't turn up anything.

It looks like the 030s use a 2.0mm pitch IDC50 header. Does anyone sell an adapter for these? I'm guessing no, but figured I'd check before I start exploring more painful routes.

I was never able to find anything with my X68030, so I opted for an external SCSI solution instead.

I have had several, but they are dangerous because they have power, I made a short circuit with an aztecmonster to put it backwards, although as the computer is well done I do not damage it except in a couple of fuses that are for that.

Is the pinout actually different from the usual connector? If not I could mock up a straight adapter fairly easily.

Update: It does NOT use the standard SCSI IDC50 pinout.

If someone can produce a correct pinout, I just need to update my adapter and I can release files. The thing costs less than $20 shipped.

Update 2: Found the pinout. It's actually some kind of weird 40 pin + 8 pin jobby that often gets combined into 50 pin. Will work up an adapter shortly. lets just hope my bad adapter didn't damage the SCSI bus.

Ok!

This seems to work.

Mostly..

I burned the image from the NFG file archive, and if I boot from floppy, I can drop back into console, CD to the drive, launch games, etc. However, if I try to boot from it (with boot set to STD) I just get a blank screen. I THINK this is just me missing a configuration step somewhere.

Maybe someone's seen this before? There's not a ton of 030 specific information out there, and a lot of the remaining information seems to be SASI oriented; often being very unclear as to which machines require which steps.
