I could have sworn that VT220 was fine and the cable wired correctly... but to cover all bases I tried it with a USB serial port on the Mac that sits in the lab. It worked. First time.

On close examination the collection contained ONE console tape... for an 11/750 of course! So I'll be reaching for an emulator. Looking back at a long thread on vintage-computers last year it appears that tu58em had timing issues and was unusable on 11/730 but is now patched and working correctly... watch this space! Thanks for all the pointers.
