I either need to find someone who knows what
they're doing with a TU77,
or someone who has and can get rid of a TM03 formatter for a TU77 with
the special 18-bit card.
Earlier this year, a team of people rescued a couple (three) KS10
systems along with RP06s and TU77s... the TU77s were confirmed to
have the mentioned board...
Chris Zach (cz(a)alembic.crystel.com) has the MIT-AI
KS10, and wants to run
ITS on it, but his tape drive (A TU77) is screwed up. It generates a
FORMATTER ERROR in the Status register whenever it's on.
He has booted from drives on the same Massbus so that's OK.
Before I offer the board we have (on loan only, of course), I would
have to talk with the others at the Rhode Island Computer Museum,
but I would also have to confirm with you (and him) that the board
that was in his tape drives did not go bad due to something else.
I'd hate to see a known good board used in place of a bad one, only
to have it go bad because the underlying problem has not been
corrected.
So... why is his board bad? Age? Or did something else go bad
and take it for a ride? If the latter, has the problem been
fixed (for sure)?
