The TEC are a rather obscure drive. I cannot recall when I last
saw one.

Are you aware that you can add an additional two drives on to the
B drive cable? Takes a new cable obviously with additional
connectors and the added drives must be set for DS 3 & 4. Also,
the terminator should move to the last drive.

I am not setup for scanning, but could probably get a copy made.
It is about 100 pages (double side) and 5 11x17 schematics.
Covers the MD-1 and 3 and also the 3HD (briefly). Not sure what
it would cost to get copied.

I supported a local attorney who kept his office running on a
group of MDs. I still have a couple here yet - a 3 and a 3H I
believe.
