Hi, this is a strange problem. I can only guess what's going on. If it's a software issue, these things are worth a try. a) run DOS in Real-Mode (no V86, EMM386, QEMM) b) don't load umbpci.sys (if installed) c) try to temporarily disable MSCDEX and CD-ROM drivers d) don't load SmartDrive The CD-ROM …

Hm. I've once used to have an Hauppauge WinTV board with Windows 3.1 software. It had a TV tuner and could encode MPEG. I wonder if the chips on the board (full-size ISA) also had decoding functionality. Not sure if the software ran on an 286, also. Audio wise, I remember playing back VOC and WAVE …

Interesting, didn't know you cannot mix socketed and slotted RAM. Although I would prefer the socketed ones as they look way more cool, I can see 1MB being somewhat limiting. I second that. I know, this story is getting old now, but I was long time 286 user in the 90s, when many had a 386 or 486. …

I need something for VGA Dos for 286/8Mhz. Hm. That's tricky. I've tinkered with CompuShow 2000, a picture viewer, in the past few days. Mainly in PCem with 8088 and 286 machines. It seems to me that decoding bigger stuff had a good use for XMS or EMS memory. So I assume it's worse with pictures in …

CPU is not emulated, the card got a real 80286. Today, people use emulation about emulating cpu in software, back then these kind of card was always refered to as emulator cards. That's because it's both emulation. The Amiga bridgeboards and PC daughter boards were "hardware emulators". They had …

Old compaqs have the bios stored on the HDD* and if you remove it you need a boot disk. Possibly the HDD is bad? Try the boot disk. *This is probably a simplification From Compaq LTE/286's Technical Reference Guide: "The BIOS for the COMPAQ LTE/286 and LTE Personal Computers resides in a pair of …

Is that same PSU as used in the Tower AT model? I'm asking, because I've essentially rebuilt that thing a few years ago. 😁 It took some tome, but it was worth it. Replacing the diodes by bigger ones (4007?) helped. My MOSFET was broken, too. Other than that, my memory is a bit foggy. I vaguely …
