Yep, even ran DTF with them flipped the other way around out of

Now that I've gotten the full suite of diagnostics to run, the problem
seems to be that the TC11 isn't reading properly in reverse -- Tests
15,16,21,22,26,27 and 34 of ZTCD fail, all others pass (modulo a marginal
block on the tape causing a failure here and there). This would probably
explain why DTF fails immediately after writing T&M, since it works in
reverse from that point...
Time to sit down with the schematics and figure out where the problem may
lie.

with the TC11 system," and I haven't
managed to find it. I *have* found
this:
http://mirrors.pdp-11.ru/inf.informatik.uni-stuttgart.de/pdp11/dtf.mac
... which is simply a mirror of our FTP server at
ftp://ftp.informatik.uni-stuttgart.de/pub/cm/...
I enhanced DTF with some useful messages and error/status output. IIRC the
"original" version produced no messages at all.
(1) above, I'm not averse to thinking there may be more than meets the eye
with this issue.
So in a nutshell: Anyone used a TC11 on a later PDP-11 (like the 11/44)?
Anyone have any thoughts on the diagnostics and formatter issues?
I have a TC11 with TU56 on our 11/34. Did you check the WRTM/WALL switches?
