I would like to inform that I've started collecting preorders for NokturnFM2 / NokturnFM3 cartridges. NokturnFM2 and NokturnFM3 are Atari ST (and compatible) sound cartridges equipped with OPL2 (YM3812) and OPL3 (YMF262-M) soundchips enabling FM sound synthesis capabilities with minimal cpu overhead. More details can be found find in official announcement (https://nokturnal.pl/posts/nokturnfm_preorders). #atarist #opl2 #opl3 #NokturnFM #YM3812 #YMF262-M

Spend several days on hooking up and testing my OPL2/3 backend (FMlib) and integrated it with SCUMMVM to allow AdLib emulation via real Yamaha OPL soundchips (like those found in my NokturnFM cartridges) on 16/32 bit Atari's. I've recorded some footage directly from hardware (unfortunately video is a garbage from composite output, couldn't grab it the other way ;(, but on RGB monitor it looks awesome). #atarifalcon030 #OPL2 #scummvm #ct60 #NokturnFM #atari

#atarist #opl2 #opl3 #nokturnfm I've published official webpage containing info related to NokturnFM2 / 3 cartridges, which allow use of Yamaha OPL2 / 3 soundchips with Atari ST and up. Right now is rather short project description, some programming info and NokturnFM.play, which allows music replay with various devices. Not everything is there yet, lot's of work, not much time, so stay tuned. https://nokturnal.pl/home/atari/nokturnfm

I've improved NokturnFM2/3 carts a little, I've added plastic spacers, so they will not hang on rom port (got to drill bigger holes in pcb, due M2,5 spacers) and I've changed old linear potentiometer to logarythmic in NokturnFM2, which was good choice, because on old one in the middle of the range i've got audio distortions (no surprise). I also experiment with alternative opamps on both cart types. #atarist #nokturnfm #opl2 #opl3

I've just ordered parts for small batch of NokturnFM2, NokturnFM3 carts (10pcs each). Ordering parts is exhausting.. Took me like 5h today. Hopefully I had BOM list with links to parts, which halved the amount of work needed to assembly everything. Worst thing is syncing order with existing electronic parts inventory (to not end up with alot of unused parts). #atarist #opl2 #opl3 #nokturnfm I've also decided to give up cartridge case for now.
