Re: Newly made PCMCIA sound card

Posted on 2021-03-18, 06:31

I am starting to feel quite confident about this DMA emulation, I have a very rough proof of concept working I think I could do it. If performance becomes an issue somebody smart can rewrite in assembly. I do need to figure out how many people would want these cards. Once I have some further …

DOOM is an excellent reference point IMO. As it reperesents a number of good games based on the same engine. Another group of games that is probably worth testing are those using Miles Sound System. https://www.mobygames.com/game-group/sound-engine-ailmiles-sound-system okay that is great, because …

Most DIGPAK games were real mode games, actually. But again, at least some of the DIGPAK drivers appear to have 386 instructions in their assembly sources. Considering the overseas shipping (slow and overpriced), you'll probably get to test it a lot quicker than I will. We might want to open a …

Hello, The problem with PCMCIA/Cardbus/Expresscard is the very thin and tightly enclosed space for electronics inside the host device, sans active cooling, which leads to overheating, heat induced signal noise and EMI troubles. Futhermore, the fan-out cables need to protrude anyhow and are prone to …

Hmmmmm 8Khz is abysmal... it sounds like making a long-distance, international phone-call during the 1930s ;) LOL To be fair, most DOS games that even had digital SFX had samples that played back at 11kHz or less. So it wouldn't sound that much worse in most of them. It's interesting to try though, …

Hello, One doesn't really need external storage since 32/64MB internal upgrades are available for the HP100/200LX through 3rd party and that's a lot of space for an XT-class palmtop. The Omnigo 700LX (a 200LX which cradles a Nokia 2110 GMS phone at the top has two PCMCIA interfaces by factory …

I've got an HP 100LX and I've always thought it would be neat to have a sort of super PCMCIA card which can do storage, network and sound all in one ...

Changing the Mouse Pointer in Windows 3.0???

Posted on 2021-03-05, 20:44

in Windows
Hi all, I'm using windows 3.0 successfully with various apps on my HP200LX Palmtop with its 27-year-old LCD panel in 620x200 monochrome (CGA). As most of you know, these old LCD panels had horrible update speeds and as such it's quite easy losing track of your tiny mouse pointer in Windows 3.0 on an …
