I have a copy of the PCjr Technical Reference Manual.
Does that book give the pinout for the serial port? The dang PCjr uses
screwy IBM square connectors. I had a need at one point to connect my
PCjr to a serial terminal server, but I didn't have the pinouts to make
an adaptor.
Any other goodies in that book? (It was probably the book used when a guy
built a few PCjr monitor adaptors to hook them up to CGA cards... I still
have a few of the adaptors... someday I should right down their config in
case I have to make a new one)
