Inventory databases used and still use nothing more than text-mode. I've seen these Clipper style applications a lot in the past decades. They're still in use, work fine. In fact, I still see no need to upgrade to VGA here. Hercules isn't CGA, after all. It's a serious and dependable thing. Places I …

I think the same. I also believe to see an NE558 timer IC and the required glue logic. These ~5 TTL ICs on the left.. My Lindy gameport card has them, too. Edit: Here it is (hi-res). Please have a look at these wonderful discreet parts! Even the little charging caps for the 558 timer's time base are …

It's possible with an external MMU. They exist(ed) for 80286 systems. PC-MOS/386 supported at least one model. I think it's also possible to use memory of an UMB card in the A segment, to simulate the MCGA video memory. Well, at least the 64KB of the page frame. VGA uses bank-switched memory in …

My main concern is the power supply. The installed supply looks like a standard ATX supply, and I imagine that IBM machines stick to standards. So, is it safe for me to just plug my modern PSU into the daughterboard's ATX power socket? I know that Dell at some point used proprietary pinouts on …

Does MSCD00 0 work as a device name, at all ? I always assumed MSCD00 1 was the default. Pretty sure that’s just a string, the number isn’t an integer and isn’t checked. You can call it whatever you like, so long as you are calling it the same thing in config.sys and autoexec.bat. Hence why in most …

Quick update. I checked the internet for the RtlFreeHeap issue. It seems to be related to the NT Native API. It has to do with the PE loader, too, I think. Windows 9x doesn't seem to be affected. Well, Windows 95, at least. Windows 98 was the first one to incorporate parts of the NT kernal. "NTKERN. …

This is interesting! Odin (o.8.9) on OS/2 Warp can execute the MZ700WIN* binaries (Win32 EXEs) with the MSVCRT dependency just fine (my compile with an relocation table and the original file), but has trouble with the CRTDLL legacy version of my compiled binary. Apparently, the latter library is not …

DOS-based Windows messed up so many things. The serial port timings, the PIT, the waiting/idle loops in DOS programs, the video memory. Yes, this is especially with Windows versions prior 9x where many of these issues originated. At least Windows 9x made several improvements and even has some …

Alternatively, MS Virtual PC 2004/2007 are an option for XP PCs. They can easily run a copy of a true blue MS-DOS 6.2x in a window (or in full screen). The emulated S3 card with VESA support is good enough for many later DOS games. Sound Blaster 16 and OPL2 level FM are available, too. Together with …
