Do you have another keyboard you can test with your computer, or another computer you can test with your keyboard? It'd be good to know if the problem is with the keyboard or computer. Could be lots of things at the moment, including just dirty/corroded connectors or an intermittent connection/ …

Nice board indeed and for $60 on ebay... finding any memory expansion cards for it will be doubtful. being located in texas makes the shipping prohibitive for me. Also doubtful that you can put a 386dx40 on it. no cache is also sad. changing the cmos battery implies modding the dallas chip. Thanks …

It sounds like it's trying to write a virus to any disks in drives. Find a clean set of 6.22 disks and on another computer make a bare boot disk with MSAV on it (Microsoft Anti Virus) should come with full DOS set. It's old, but then so is the virus very likely. Maybe "stoned" or similar (virus …

As discussed in the thread I linked, it works for real mode applications only, which eliminates most 386 apps, including Jazz Jackrabbit. Yes, I'm afraid that's the case. Early 386 games from the 90s usually like to use that "flat-mode" model, also. I'm afraid the only feasible method of running …

A picture of the board would help, but usually for boards of that era there is an oscillator that determines the CPU frequency, in some cases it's 1 to 1 (e.g. 33MHz oscillator to run the CPU at 33MHz) but sometimes there's a divider (66MHz oscillator for 33MHz CPU). So if you want to change the …

What could happen? Depending on the installed oscillator crystal, your CPU designed for running at 20MHz will be run at 33MHz or 40MHz. It's not going to boot. Potentially it might get damaged, but probably won't due to not even booting. Thanks so much for answer. In that case i wont try it at all, …
