It was internal and primary use was diagnostis as it was on a serial
line making it the easiest thing to bring up.

Also the 11/44 interface was slow for some reason and the TU58 was
limited to 4800 baud or the 44 would lose data.

I have several but I do use them. I can read tape and transfer to
RX01/2. This is assumeing the tapes are still good (binder isn't
flaking).

Yes, I have an 11/23 with an external TU58 that runs RT11. The one
internal to the 44 could also run RT if memory serves. RT11/TU58 expects
a DL compatable serial line to use the DD driver.
