Thanks for that, but unfortunately it is crashing into
ODT and not
accepting input from the console, which I remember was a symptom of no
bank 0 memory.
Now,of course, it could be the receiver chip in the J board (I used to
make a lot of money changing them ) but I have tried two separate J boards.
Of course if it is 4 MB, it must be in bank zero.
cheers,

Can you read any of the CSR registers built into the serial board or cpu
without the memory card inserted??? I don't believe ODT is dependent on
working memory.
