Could someone *PLEASE* help me...
A collegue of mine has purchased:
- An IBM PCjr RGB Monitor
- A Leading Edge PCXT clone (with color graphics card)
The Leading Edge pinouts are known (for the color graphics board),
but the signal inputs are *NOT* known for the IBM PCjr's color
monitor. We have had no luck in obtaining information from IBM
on the monitor, and know of no one with the PCjr. The connector
one the monitor cable is the "header" type, and the Leading Edge
expects a female, 9-pin D connector, just like the IBM PC.
Also, how do they number the pins on a "header" connector?
I noticed that there was a notch adjacent to one of the pins,
(I guess this is pin #1), but I don't know where to go from there.
Thank you ever so much for your time...

A few months back we got hold of several PCjr color monitors at a bargain basement price. We quickly adapted them to connect to a PC color card. It'll take about a half hour of your time to hack the PCjr connector off the end of the cable and put a 9-pin male connector in its place. To keep things simple, I'll draw you a picture of how it's wired: pink, braided blue green red grey, shield clear ___________________________ / \ PIN 5 | o o o o o | PIN 1 \ / PIN 9 \ o o o o / PIN 6 \_______________________/ yellow brown (open) orange This is the view as you look at the pins to which you solder the wires, *not* as you look into the open connector end. Note that one pin (7) is unused, and another pin (2) has three wires connected to it. Actually, you might want to ground pin 7; I think that was the sound input. If you leave it open, you'll have to turn down the volume on the monitor or else you'll get a rather obnoxious buzz (kind of like Flight Simulator sound effects). bill frolik hp-pcd!bill
