I have an IBM WDL-320 hard drive here which is a 20MB ST-506 style drive from a PS/2 Model 30. It has a single card edge connector which combines both power and signals, and I don't have anything that it can plug into.

Does anybody have a pinout handy before I go on another quest? I'd like to at least spin it up to see what it does. Testing it in a real PS/2 Model 30 would be best; I'm in the Seattle area if anybody can help.


Thanks,
Mike

Here is your pinout for the two cables. Looks like you just need two cables.

One site I looked at said it is a 30MB drive.

I had many of that type of drive and they all died years and years and years ago. It seems they had a very short life span so don't feel too bad if you can't manage to hook it up as you'd likely find out it was not useable anyway.

I might be missing something here, but this drive has a single, 44 pin card edge connector. It's not like any MFM drive I have. It has a set of four pins (2 on top of the card edge connector and 2 on the bottom) and then another set of 40 pins (20 on top, 20 on the bottom). It does not look like anything that you linked to.

Tis a strange interface.

I have both a model 25 and 30 that could use it. :) But yea, they are almost total trash. I had 10 drives get to me on ebay, only one worked, and it had about 10% bad sectors.

so yea. one of my pie-in-the-sky projects is to make some sort of adapter to CF.
