Yeah, the point being that it was the BIOS that made it compatible, remapping all hardware to a common interface, so if it doesn't quite mesh with what is on the board, problems will ensue... Particularly if the BIOS was intended for a 188 or V40 chip with internal peripherals like timer etc which …

I can attest, I had MBC-555, Not fully compatible and comes up to 256K only using 64K x 1 chips, no ISA slot or ISA signals provisions. Due to not quite compatible, I had less interest in it. Back then I was given three MBC-555 computers with no options, floppy drives only, with office software. No …

Now that I think about it, there's merely so much you can do about badly coded software. How about a more analog solution? Is it possible to physically reduce the memory on the RAM modules? Like, using a hot air station to carefully get rid of some chips? Or, is it possible to disable some modules …

Hi there! The joystick problem could have several origins. Could be a speed issue, for example. Newer gameports in 16-Bit soundcards had to be speed-compensated (doing it automatically). Some high-end game cards in the 80s had a trim pot for this purpose. Issue of the problem: The PC gameport works …

The Weiteks also had lesser accuracy over x87.. 80-Bit as a temporary format was handy for computing multiple calculations with each others, for adding/multiplicating large numbers. That's what people forget, I think, if they think 80-Bit are unnecessary. For CAD/CAM or graphis in general, Weitek …

Hi there! That version seems to use FlashFloppy, which is fine. FlashFloppy is an alternative firmware that's better than the normal Gotek firmware. It works with a large number of home computers and PCs. For an Amiga HxC might be even better, since that's what it is made for. However, HxC is a …

If you, the user, merely has a lousy 1MB in your AT class computer, then you're better off running CP/M, anyway. I would say that an AT with 1 MB RAM is already asking for a protected mode OS. It depends, I think. 640KB were not enough to most DOS programs alone, single-tasked. I'm not eager to see …

Hi again! I found out about an vintage utility called "Advanced Disk Managment". It had, - among other things -, the ability to create paritions beyond 32MB. Up to 512MB, if I'm not mistaken. Very interesting. Maybe this was one of the tools that were used in the DOS 2/3 times ?

If you're an audiophile or fan of trucker music, use the AWE. The EMU 8000 is supported by Impluse Tracker, so the CPU is freed from the task of mixing and up/down sampling. The 8-Bit Soundblaster and the Thunderbird are neat for testing purposes, for best AdLib/OPL2 compatibility. Don't throw the …

What you guys can theoretical try is using one of the PATA to SCSI converter boards. They used to exist in the early 90s, afaik. SCSI as such didn't have the compatibility issues we're used to. It's a fully featured bus, essentially. Modern USB to SCSI converters should be able to talk to those old …
