Given the vagaries of tape, I'm surprised nobody has made a simple TU58
emulator that can feed the proper microcode bits to the 11/730...
Then again, maybe there's no market for that.

I'm pretty sure that I have a complete set of 11/730 TU58 tapes in
my storage unit. I might even have some brand new tapes. If I
can find them, I would be happy to send them to you. They have
been sitting in storage for probably 20 years, so there are no
guarantee that they are readable.
Thanks... I will certanly give them a go. I am pretty sure the problem
I am having is the tape, I get a low (and varying) amplitude signal at
the output of the read amplifier, it varies with different tapes, and it's
much the same both on the drive in the 11/730 and a standalone
TU58 I have.
until the
8085 CFE loaded the microcode.
Loaded from a TU58 cartridge, which is the main reason my 11/730 is not
running at the moment. The hardware is fine, I've rebuilt the drive
rollers,
but as yet don't have a readable tape (not even blank, to write the
microcode onto).
