DTC stands for Data Technologies Corp and they're still in business, with a web
site at
http://www.datatechnology.com/ and there are info and setup docs
available at TheRef(c) as well, located at
http://theref.c3d.rl.af.mil/.
MFM, RLL and ESDI contollers generally have one 34 pin header for the "data"
cable (and some have another 34 for the floppy controller) and two 20 pin
"control" cables, one for each drive the controller is capable of interfacing
to. IDE controllers have one or two 40 pin headers (and possibly a 34 for
floppies).
There are other things the controllers should be looked at for in the older
machines as well. The average MFM, RLL controllers are usually a 1:3 or 1:4
interleave controller but many of the better ones are 1:1 interleave.
