As it is, I have a gglabs CGA to VGA, but I need an upscaler to connect it to a flat panel VGA device... Or do I have to keep chaining stuff together?

Is there a single device that upscales and suports EGA and CGA

Well, everything is sold out

I’ll have to take a look at what I have laying around for chaining stuff together… I have something that connects a CoCo 3 RGB to HDMI, as I recall. I had to use two devices…

Hmmm there was one RGBtoHDMI when I posted those links, somebody must have bought it. EternalCRT is another version of the MCE2VGA but it is also sold out. Probably due to the FPGA shortage.

I use the open source scan converter (OSSC) It’s worked with everything I’ve thrown at it, including cga, ega, vga, video game consoles, x68000, apple ii, pc-8801, pc-9801, Mac black and white displays, apple iiGS… I can’t remember if I’ve run into something it didn’t work with.
HOWEVER - It’s worth noting that you need a de-15 (vga connector) input. For EGA I use a home made adapter with a few resistors that doesn’t do scan conversion but converts the three rgb signals as necessary. The OSSC does the scan conversion as necessary.
If you really only plan to use it for CGA and EGA and you want to save money and effort maybe you should wait for one of the other devices to come into stock.

I was looking at OSCC, but couldn’t tell if it would work. Now to find a board… I’ve never done surface mount parts, just through hole stuff.

Just to be absolutely clear, I made this 3 or 4 years ago and it’s an abomination, yet it worked fine even without any soldering skills at the time - 100% breadboard and wires.
I tossed it in a black plastic project box and called it a day. These pictures are actually before I got my OSSC - they are just using some random lcd that happened to be able to sync to ega frequencies. It’s not the most straightforward solution for ega/cga and you might actually need a different adapter for each one (different pin outs) but the OSSC is ultimately very versatile and useful if you have other old machines.

I just got the Texelec RGB2HDMI https://texelec.com/product/rgbtohdmi-ttl/ device, works fantastic. Also supports MDA. They just ran out, but they restock quickly.
