It seems that ffdshow (32 bit) should be able to decode Indeo 5 (so Virtualdub can use it to reencode the videos). Also, if you are brave enough to use a command line program, ffmpeg can convert IV50 videos. It can read Indeo videos, but I don't know if it can write back to IV32. Also keep in mind …

eta: I assume that if this machine had been a success Amstrad would have released special expansion cards to fit it. I don't think so. This computer hit the market when Amstrad own PC1512 and PC1640 were already obsolete (and in some cases, cheaper) because almost everybody was moving into 286. …

It"s not easy. Atari style joysticks and Sega pads (those with DB9 connectors) can be easily converted, but NES, SNES and PS use a serial protocol. That protocol needs a clock signal generated on the console side, and the PC joystick port has no output signal. You'll need a converter (probably with …

There were a time when 10baseT (RJ45) was growing but there were lots of 10base2 (BNC) networks. At that time there were switches that had RJ45 connections (even small switches with 4 RJ45 connections) and a single BNC connector to join old and new networks. Also, I'm sure that you could connect …

Adlib. The proper sound for a 8086 would be an Adlib card. Also, a parallel to ethernet adapter could be used instead of an ISA card but those things are expensive. The network card would be useful if you intend to copy files from/to the PC200, but if you use a idecf card or (cheap but slow) a …

You've got some problems. You'll want to add: - An xtide card (or an idecf card) plus HDD. - A VGA - A sound card. - A network card to transfer files. That's four cards, and you have serious space restrictions. At least, I'd try to get the first two cards... unless somebody make a combo card that …

AFAIK, the source released by ID uses different (slower) libraries for sound and ports may be slower. Also, modern ports may use modern libraries (DirectX, OpenGL) that may not be available on your CPU/OS/VGA or perform slower.

They're planning to use the extra memory as EMS, so it will run with 8086. There is a repository that contains everything related to the project, so the VHDL description may have been uploaded there.

I guess not. Text format in memory was character-attributes-character-attributes... if you wanted more colours for foreground and background colors, you'll need more bits so you'll end breaking up that "standard". Note that graphic modes usually could display text via BIOS calls (int 10 allows up to …

Software may be a issue, too. DXVA was not supported on Win 98, so players had to have their own acceleration support. Your best choice would be using an old version of PowerDVD that supports your video card (maybe PowerDVD 1.6?). Another option would be using an old version of GeeXboX (a bootable …

It's a DLL that allows (or emulates) direct access to hardware (something forbidden on Windows 2000, XP and later). Willem uses it to access LPT port directly. There is an alternate (or maybe a wrapper) DLL that "translates" between addresses, so a write to port 0x378 may be redirected to 0x9800 (an …
