Swapping pins 2 and 3 on an rs232 is a common trick - I almost mentioned it and now sorry
I didn't.
Thanks for capturing the SVC ROM. It will be worth doing an image of the hard disk
over T-NET for use with simulators etc (Including xbeaver
).
Disked can copy an entire disk over into a file on a t-net server I have done it with
floppies.
Best wishes on the move.
