Very Old Hard Drive

So, in my quest to gather 20 pounds of hard drive boards, I stumbled upon a very, very old hard drive. The model is IBM DT542B-4A.

I can't find any information on it anywhere, and the hard drive board is so old it has gold fingers.



When I get a minute, I'll take a few photos and share. Just an odd find I hadn't come across yet.

I actually found it and was looking at the wrong model #. Here's a link to Wikipedia about it, with a picture. Scroll about half way down to where it says storage and there's a picture of it with the gold fingers. IBM Personal System/2 - Wikipedia, the free encyclopedia

how many megs is that drive?

Heh! Sorry. I actually found 2 more of them. Just thought they were interesting.

That's the prollum. I started reading and reading and looking and looking and am still here reading and reading. I need a nap, now. lol

This should shed some light on the drive size: http://www.walshcomptech.com/selectpccbbs/83g8990.zip
