I'm afraid that I'm no help either. I assume you've probably already
checked computerhope.com. I can't tell you how much good info I've found on
that site. The link below is as close as I could get, but unfortunately no
4021. I don't see how it could be IDE as that's a 40 pin connector. It is
perhaps slightly interesting that the 3021 is a 20 meg drive. Perhaps the
4021 was a custom mod of the 3021 for Compaq? I have read that some of
their devices were intentionally incompatible with the rest of the PC world,
though I've never personally confirmed that.
BTW, this is the first time I've tried replying to the group since I
switched to non-digest mode so please excuse any goofs. Since I also
subscribed to cctalk at the same time, I had to look at the message source
to see which group the message was actually from. Some of the posts show in
the To field as cctalk at classiccmp.org while others show as "General
Discussion: On-Topic and Off-Topic Posts". I'm wondering now if all the
latter are from cctech. If I can trust that it will simplify life a bit in
