I've got a serial I/O board in my H-89 that transmits data, but doesn't
receive it. I've replaced the 1489 on the off chance it was blown, but
no change was noticed. The serial cable is ok.
Can someone point me to a set of schematics for this board? It's the
"multi i/o" board with 2 serial (apparently) and one parallel port.
Thanks all!
