That's good to know on the LEDs. Yes I checked the PSU first; three
red lights. The baud rate switches are set for 4800 - the default.
think I have the console cable correct - and just in case I buggered
the Rx/Tx I tried it with them swapped. Nothing. Never so much as a
garbage character on the terminal - and I know the terminal works ok!
Nothing funky in the settings there as far as I can see.

Anything you can tell me about  the POST on your machine - the timing
- what appears on the console and when etc. - would be helpful.

I plan to use an Arduino-based TU58 emulator when the time comes =
although I would like real working TU58s too!
