I was just wondering if there is a RGBtoHDMI profile for the Tandy 2000 640x400 color mode instead of using a CM-1 monitor? It would be nice to take the monitor out from time to time, but I would rather put less hours on it and use the RGBtoHDMI instead.

I decided to give this a try to see how well it works. After a little trial and error I can say this is a really cool option if you have writable memory between 640K-1MB. I tried it out in my NuXT v2.0 motherboard which has UMBs enabled for C800-DFFF. I specified C800 as the start address in the …

Well it turned to be the NEC V20. Monotech PC suggested I try a different CPU. I tested with both an 8088 and the replacement V20 and everything is now working. I would not have guessed that to be the issue, especially with it working with everything else. I am just glad the issue is resolved.

I bought a NuXT v2.0 motherboard back in April 2020. It has worked with no issues since I have gotten it. All of the sudden the 8087 math coprocessor is not working. It is as if it is not even plugged into the socket. Now I now the 8087 itself is Ok, since I have tried it in another computer and it …

Beelink is generic made quality too. We had one die for wall monitor serving advertising video. Next time, if you want, I suggest HP elitedesk 800 G3 mini. Plenty of them for about 150 for i5 and 16GB. Supply your own SSD either Sata or NVME. Socket is 1151 LGA means you can upgrade. If you need …
