Okay, I’m too excited to keep this hidden any more. I was debating on whether I should announce this before I had working examples, but...

This is an official announcement for my YM2608 cart for MSX. Special thanks to @leo__oliveira for letting me adapt his initial project.

I bought the Minto ass shirt, the Densetsu.EXE happi, and grew my hair out for a year and a half to be this guy.

A single version with both 4256 and 16256 proved too difficult to route on a single board.... it takes up too much space, which then can't be used to recreate the DAC on the board. Therefore, two versions have been created.

Final revision of "SCC Sound Cartridge+" for MSX.

@AlabamaZigga what kind of violations?

uwaaa SCC++ PCB

(Please note that either SOJ or DIP memory can be used at one time, both can not be used as they will occupy the same memory area, this cartridge can not use 1MB, only 512KB).

Completed SCC+ 512k schematic.

Passives added, and organized slightly better.

Based on elec-junker-p2 schematic. PCB layout will begin tomorrow.

New project...
SCC+ 512k DRAM, high memory "Sound Cartridge+"
I love MSX....

Anyway, with all the current Backrooms hype, and theories on the nature of The Complex and its true workings, anyone interested in the "alternate reality built from experiences and reinterpreted memories" should check out this little anime from ten years ago called Flip Flappers.

@nukeykt The date code format would have told you it's a Yamaha part.

I'm an American retro PC enthusiast who loves Showa-era Japanese technology. Sadly, due to my circumstances, I'm afraid I'll never be able to experience things like seeing Win3.1 or DOS/V on shelves in Akihabara. The last sparks of "Electric Akiba" are fading too quickly now.

@nishikazuhiko Mr. Nishi, thank you for your reply.

The community has made both hardware and software targeting OPNA on MSX at I/O #14-17h. Both I with SuperSoniqs and Niga-san have released products described as "Makoto-compatible" using this I/O. There is support!

I fucking love Aviamarch so much, favorite march next to Anchors Aweigh tbh.

A fun little bit about Yamaha's FM history is that the YM2151 OPM, introduced with MSX, also started possibly the only pinout standard in Yamaha's entire IC lineage.

1.
2151 (OPM)
2164 (OPP)
2167 (OPP2)
2414 (OPZ)

2.
2160 (OPCW2)

3.
OPL1/2/3

The difference is only pins 10-12.
