My Data  I/O 29B seems to have died. Passes self test but does not actually 
work! After  pulling it apart there is a dead PROM (324-1031-001 Rev A). 
All the inputs are  OK but no outputs. This is an I/O decoder and seems to 
control most of the R/W  funtions & the RS232 output as well. Can anyone sell 
me a replacement  PROM? 
Thanks in advance.


Hi Phil
 
I can't help with the PROM but do have a PDF manual from October  84 that 
includes circuit diagrams and some technical info.
If you haven't already got it you're more than welcome to a  copy.
 
regards
