Thanks, I see that now. Definitely no compatibility :-(. Just need that
logic analyser really to work out what is the matter with them both. When
the 380 doesn't have the daughter board installed it leaves all the LEDs on
to indicate a system board error. The 350 has the same symptoms with or
without the memory boards. Strange though that the manual mentions a
standard option with memory on the backplane, I don't think my 350 had that
installed. I also notice that the printer port can give access to ODT, I
will see if I can get anything out of that later.
The printer port is either a 4800 baud port intented to drive the printer, or a 9600 baud
at the standard console UART address. Which it is depends on the connected cable; BCC05
is for printer, BCC08 is for console. Or you can wire your own. The difference is that
one (the BCC08, I think) has a jumper which tells the hardware to be a console.
