Well, it is a long time tradition actually, there was a well known Commodore 1541 Floppy Drive which also actually was a standalone computer. 🙂 Do you have a link to that ? https://en.wikipedia.org/wiki/Commodore_1541 This thing has its own CPU, RAM, ROM and even DOS 🙂 If you guys ever trying to …

The HP200LX seems to have a PCMCIA slot, so it might be possible to install an USB PCMCIA card. Together with matching drivers (PCMCIA card services or PC Card services etc) it might run on the 200LX. That being said, it's not too easy to find something on the web. Google nolonger obeys the …

Ah, I see. Makes sense to me. Speaking of FPU/NPU emulators, the "Franke 387" emulator was very sophisticated. Or so I heard. In Germany, there was a lot of advertising for that FPU emulator back in the late 80s/early 90s. http://icfs.de/franke387.html

According to the Amiga folks, there was that CFU950 chip for 16-Bit PCMCIA, but actual cards using it became very rare. 🙁 https://www.alldatasheet.com/datasheet-pdf/pdf/188079/OXFORD/OXCFU950_07.html Maybe using Compact Flash cards is an alternative. They are kind of pin compatible to PCMCIA, but …

Indeed, I heard about this. The 386 doesn't need a 387 that badly. Unlike 286/287 and before. In AutoSketch on an older architecture, the performance CPU vs FPU is more dramatic. https://www.youtube.com/watch?v=ItA-_D2QkTk https://www.youtube.com/watch?v=SGCUErENKBA https://www.youtube.com/watch …

I haven't tried yet, but to my understanding, disconnecting C6, by removing or lifting one leg, could get rid of the noise comming from the Chroma signal without completely breaking the RF modulator or the normal AV cables. Both would still work and output clean video in grayscale, because the pure …

Hi everyone, I would like to inform you about a special case: Unlike Windows, MS-DOS itself doesn't need partitions. It's possible to format a flash medium or a HDD as a "super floppy".

That's right, XTs had a different keyboard protocol, as well. Some people even say it was more simple, but also more elegant than the AT protocol. From what I vaguely remember, it didn't need to lock/unlock keys (?) in the same was as the AT protocol does need to do.
