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
 
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.

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 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.
 
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.
