Anyone know what kind of interface a Conner CP-4021 uses, and if it's
something standard, what the pinout is?
This is a 20mb drive from an old Compaq LTE (8088) laptop. I'm trying
to recover some data from it, and the laptop itself is dead. It appears
to have a 44-pin connector in some form-factor I've not seen before.
This is split out into two ribbon cables that plug into the laptop's
motherboard. Can't find anything on the net. Found a site selling 'em
as "0.02gb" drives, though :). (This site claims it's an IDE, I'm not
so sure... though it would be nice.)
Thanks,
Josh

I think that might be an IDE with power on the extra 4 pins.

I used to have one in an old 286 laptop, but that drive has since
died. Isn't it the standard IDE pinout used on most 2.5" laptop
drives? I suppose Conner might have made multiple circuit boards for
different manufacturers with different pinouts. Is the connector 40
pins with higher density than IDE, a 1 pin gap and then 4 more power
pins?

It's not the same sized connector as a 2.5" laptop IDE. I'd guess it's
about 1/2 to 2/3 the width. It could have the same pinout, though...

This is really a 44 pin IDE squeezed together.
Put in a flash CF with adapter instead. I successfully did one with 2.5" HD
in one long ago.

The only problem with that is that the OP is trying to recover data of the disk. :-)

That what I'm aware about, Take the old cable from the notebook and
assemble homemade IDE adapter and supply 5V. Just mind the correct
grounds pattern and such. Matches the notebook 44 pin IDE pin out
exactly but just the pin spacing is different.

Subject: Conner CP-4021 interface/pinout?
Anyone know what kind of interface a Conner CP-4021
uses, and if it's
something standard, what the pinout is?
This is a 20mb drive from an old Compaq LTE (8088) laptop. I'm trying to
recover some data from it, and the laptop itself is dead. It appears to
have a 44-pin connector in some form-factor I've not seen before. This is
split out into two ribbon cables that plug into the laptop's motherboard.
Can't find anything on the net. Found a site selling 'em as "0.02gb"
drives, though :). (This site claims it's an IDE, I'm not so sure...
though it would be nice.)
Thanks,
Josh
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
the future.
