Oh sorry, it's an Emerson 4412EC. A 286-12mhz with some nice built-in features.

I've dumped the ROMs for the Emerson 4412 286 system. It's a pretty neat box, and there's not a lot of information around on it. It's got a lot of nice features: 8mb ram max, built-in hardware EMS support, boots from rom, a very in-depth self diagnostic BIOS utility. The manual hints at some sort of …

Thanks, I was able to dump it as a 27C010 chip once I figured out how to disable chip id checking.
Dumping KM23C1010 mask ROM

Can't find a lot of info on this rom, and it's not in my minipro chip supported list. Any suggestions as to what I can use to read this chip? It's the ROM of a fairly rare system it seems, I'd like to archive it for posterity.

I recently had a failed RTC oscillator. Never saw one of those before, I'm not sure how to test that at all, was just blind luck that I was able to track it down.

I've been planning on doing this with my Tandy 1100FD. Glad to see it's working for you.

I'll consider that a vote for the Voodoo2.
K6-266 with single PCI slot; what should I put there?
Posted on 2020-07-21, 17:35
I've got a super nice and clean Compaq Presario 2254 system with a K6-266 processor. Seems like it will make a pretty sweet DOS and early Win95 gaming box. It has a single PCI expansion slot. What should I put there? I have an Nvidia 6200 PCI that supposedly supports Win95/98. I also have a couple …
Which memory manager offered the TSR unload/instant reboot feature?
Posted on 2020-07-10, 17:21
I seem to remember one of the EMM386-style apps offered some dynamic TSR unloading and a "rapid" DOS restart of some sort. Does that ring a bell with anyone?
Re: Emulating MT-32 on an RPi2
Posted on 2020-07-06, 15:14
https://streamable.com/cnzpbh Playing a few sample MT32 midi files on my RPI4 2gb. If I understand htop's output it seems like it's using maybe 50% of one core for these particular midi files. I think that's plenty of leftover CPU for DOSBOX and whatever else you'd need. That's with Process all MIDI …

I have Munt running on a raspberry pi 4 2gb with full GUI and it seems to run fine, all the test MT-32 midi files I'v e played sound great. Will be running some Dosbox games through it soon.
Re: Are there any USB -> XT keyboard interface devices?
Posted on 2020-06-12, 12:39
I have a feeling that will only work for the USB keyboards with native PS/2 support built in, not all keyboards support tohse passive USB - PS2 cables, will they? I think I'll pick one up just to see though.
Re: Are there any USB -> XT keyboard interface devices?

That is nice, but I'm looking for the reverse; I want to plug a USB keyboard into my Tandy 1000TL.
Re: Are there any USB -> XT keyboard interface devices?

Yeah, and then I could daisy chain that to one of my PS2 -> XT keyboard adapters I suppose...

Posted on 2020-06-11, 21:23
Googling returns countless adapters to use your XT keyboard with USB port, but nothing for using an USB keyboard on an XT or AT keyboard system. Anyone know of a project along these lines? Possibly using a raspberry pi or arduino as a protocol interpreter?

https://ftp.sunet.se/mirror/archive/ftp.sunet … t/msdos/screen/ SS3.zip from that folder seems to do the trick just fine. No neat effects or flying toasters but screen gets blanked just fine. Also seems to blank Tandy 16-color graphics just fine.
