Those Gonbes units are not that great, they are rather noisy line doublers and require the CGA2RGB DAC. This is a superior solution : https://youtu.be/9SII7ujB3FY

The ideal solution for a modern LCD is the Open Source Scan Converter (OSSC) combined with the GCLabs CGA2RGB DAC.

Hi gents, I was excited to find this disk image to test out on my new PCjr -- but upon trying to load any of the carts from the menu, the computer locks up after a few seconds of loading.

I will definitely buy one. Please add me to your list.

Cool looking boards. A part of me wishes he put some extra material on the ends so you could permanently mount them to the case using a drill and some screws

I am wondering if anyone else has problems with their mod on some PCjr programs. Notably, I have noticed that Colorpaint doesn't display properly on my jr with the mod performed. Of course, there could always be an issue with the mod I did, but it seems that most everything else I've tried with it ...

IBM came out with an official adapter that converted the pins from the BERG-style row headers to a standard DE-9 female for the IBM 5153 PC Color Display and similar monitors.

The ideal way to capture video from CGA, PCjr., Tandy or 200-line EGA would be to use a GCLabs digital RGBI to analog RGB converter, then an Open Source Scan Converter and finally an HDMI capture card capable of at least 720p/60fps.
