I would like to use a mechanical Hard disk (no SSD) with my older motherboards (286, 386). As you know actually there is not available mechanical IDE Hard disk. I thought in SATA HD with SATA to IDE adapter. It works properly in my Pentium / 486 motherboards with integrated IDE controllers, but if …

I'm speaking under correction, but I believe that MCGA was somewhat restricted in several ways. No EGA modes, for example. Some VGA games in 320x200 refused to work on MCGA also. I wonder if MCGA's palette was "set in stone" or as flexible as that of VGA. Also an interesting read - https://trixter. …

I think the same. I've got a 20MiB HDD here from circa 1985 that had several hick-ups initially. At some point I had to switch the PC on/off/on during the seek/testphase, because the HDD lost track of its own. Back then, I was worried about sending the PSU into heaven by doing that. Gratefuly, the …

There's also MS-DOS Player. It started out as a 80286 + text-mode emulator with DOS emulation, but has grown in functionality since. Running Protected Mode programs is a challenge i guess, but so it is on NTVDM. OS/2's VDM was much more complete, IMHO. It supported things like DOS software for EPROM …

Hi, I've got a Gameport to MIDI cable, but I have no vlue where I got it from. Sorry, hah. :sweatdrop: However, there's some tip - If possible use a MIDI cable with built-in opto couplers. They prevent several issues, since both the computer and the MIDI device are fully separated from each others. …

Zeliard is indeed an interesting game, both in terms of music and technology. I once used it for testing my home made Covox Speech Thing clones and Temu (that's a Tandy 3-Voice emulator). If memory serves, there's a key combo to enabled/disable "multi-channel" PC-Speaker music if PC-Speaker is …

IBM VGA is always backward compatible with CGA/EGA. Well, yes and no. IBM VGA had a fake CGA support included by design, but it is high-level, only. It does not support any Motorola 6845 features at the register level. This causes problems with certain palettes, for example. On a VGA card you'll …

There's one thing that keeps me from using PCI cards in a pure DOS system: I haven't found one yet that has a mode utility that allows for switching to CGA/Hercules graphics emulation modes. Another "iisue" is the lack of SVGA support in older titles. Trident 8900/V7 Vega /Trident ET3K/K4 were among …
