Re: Make your own RGB monitor

That reminds me of the CGA/EGA to IIgs or other analog RGB hack I used
to do quite often.

Darn near any such monitor could be made to work by following the
R,G,B signals in from their respective pins on the DB9.

Heck, sometimes the PCB inside the monitor was even labeled for you.

Follow them to the first IC they hit, look it up in the databook.
(there wasn't any 'google', the web was .. gopher, and ProLine was
still newish.)

See that it was some sort of D to A converter and with the schematic
of the IC in hand, eliminate it. That meaning, where the signal went
in, and came out in the circuit, jump it with a wire, after having
removed the IC.

Change the DB9 or use an adapter, to 15 pin for a IIgs RGB and hook it
up.
Now you have a IIgs compatible RGB.
