What SB16 with which Wavetable module? The original SB16 doesn’t have any Wavetable features built in.

Also: Yes, Smardrive takes up memory. But if you run Memmaker you can load almost all of DOS into UMBs. Shouldn't really be a problem...

PicoMem might be good for you as it provides both EMS as well as USB for Joystick. Also, the original SoundBlaster used a Microcontroller to realize the sound functionality. This not so dissimilar to what the RP2040 does on the PicoMem and PicoGUS.

Is there any plan to integrate a Joystick port? That's about the only other thing I'd want. I would guess not. The BlasterBoard didn't have one either. There are separate Gameport or Multi I/O cards, which you can find on eBay etc. Would make sense to want it on the card if you are short on free …

I agree, do not blow up the scope of this project. Will there be an option to assemble your own card? I know it will be few people who want to do that, but I like doing SMD soldering by now, and this would be a great piece to practice on. I still have the original BlasterBoard here, even if it's …

Let's Code MS DOS 0x28: Expanded Memory (EMS) The original IBM PC and MS DOS could — for the most part — only access 640KB of memory. The LIM EMS standard was at first a standard for RAM expansion cards to overcome this limit. On later machines like the 286 and 386 there was either support built …

ZoomFloppy+OpenCBM+8050 The main issue with the Commodore 8050 and 8250 drives is: How do you get data onto them? The units use 100tpi floppy drives that are incompatible to the regular 48tpi and 96tpi disk drives used in the 1541 and in PC DD and HD drives. So there is no chance using those. …
