As someone just pointed out, this issue of Computer Shopper is devoted
to Hard Drives. If I remember it correctly, the article mentioned that
IDE used RLL logic, but the smarts are in the hard-disk itself and the
connector interface is a 40-pin type, usually on the AT/XT motherboard
(although they said you can purchase a bus IDE "adaptor" if you want IDE
and there are no motherboard connectors).
I have a PowerFlex and ALR has said they specifically support the Conner
CP-3104 (since the 40Mb disk as standard equipment is also a Conner).
Supposidly, the only thing you have to do is dip-switch the units to
indicate master and slave relationships.
I suggest just calling up ALR -- they seem to have very knowledgable
techsupport and sales support.
BTW: They best price I have seen so far (after going 1/2 through Computer
shopper) is from from an outfit in CO. -- they have the bare CP-3104
for $620.
