You're welcome! I'm glad it worked for you. Also +1 for the use of flower.skd. You've got a good taste. :) In the past I was using mntbike.skd or ericson1.skd, but this one is better. For once, because it is quite complex and because it draws all different shapes, such as curves, lines,straights, …

Hi, I don't know of any generic drivers, but I'd try the driver for the Typhoon Media Sound Advanced 16 bit. That model contains both an Opti 82C924 and a CS4231A or AD1845JP, so the driver should work fine with it. (Even if your card and the Typhoon card would do contain an EPROM which has stored …

In 1995, I had got a 286 with CD/16-Bit sound running DOS6.2/Win3.1. In 1995, my father had got a 386DX40 w/ 16MiB running Win95 RTM. And a 486 laptop w/ 4MiB, DOS6/Win3.11 and a monochrome LCD. I haven't seen an actual Pentium PC until '98-99 (at the house of a schoolfellow ?).

I think the same. Using an HD drive with an HD floppy is no problem, independent of the formatting (be it 320KB/360/KB/720KB/1.2MB or 1.44MB). Edit: Here'a the datasheet. Track density seems to be the same (135TPI) for all three "modes".

There was Flea86 but it's been discontinued. As far as OP's question, could they? Yes. Would they? No. The demand for vintage hardware rounds to zero on the scale required for it to be profitable. There's a bit of demand in industry and business still. There are x86-based Single Board Computers ( …

I think the same. GM started approximately 1993. Before, there was MT-32 (and compatibles). And generic MIDI, as well. Some Sierra games also supported popular Casio keyboards of their time (MT-540/CT-460/CSM-1/CT-660/..), as well as the IBM Music Feature Card / Yamaha FB-01. Anyway, there was no …

While I don't have got that money to spend on such a kit, I don't think it's so expensive. Sure, it is expensive in comparison to an old 8-Bit Sound Blaster or AdLib clone card you would find on a flea market, or to a plain PCB, but for a complete kit, the price is okay in my opinion.

Regarding the cost of such a chip, I'm curious, as well. On the other hand, official MPU-401 support -along with support for the Gameport- got years ago dropeed with Win Vista. While it might be possible to fix that on 32-Bit Windows, 64-Bit releases would require another solution. Maybe a cheap USB …
