anyone ever connect a TU58 drive to a PDT-11/150 terminal port?

[Chris Zach]

Very nice to know! I am repairing my tu58 bit by bit and will try it out on my 11/150. Good to know about the serial limit, I'll jumper for 2400 baud to test.

Question. The only tape I have for testing is an xxdp. Are they in rt11 format that I can test with a simple directory command?

It's a little inconvenient to work on, since it doesn't have a simple way to transfer files back and forth (KRTMIN doesn't work when transferring files to the box, just from the box, for some reason I haven't been able to puzzle out, and pasting text into a KED screen or a PIP command usually overflows my terminal emulator).

The DD driver on the PDT-11/150 will talk to a TU58 emulator on Terminal 1 just fine (presumably, it would talk to a real TU58 as well). It only works at 2400 baud, but, it's still pretty useful for moving software on and off the box. With the "big" TU58 patch to the DD driver, it's also possible to  store lots of RT11 software or data  (65000 or so blocks worth) on a virtual TU58 and load from there, rather than switching floppies. See https://rsx11.blogspot.com/2022/05/pdt-11150-and-tu58.html for the long boring story about  figuring this out.
