I do not know if this is a clone of something but the CS4232 does not have any kind of internal FM synth and there is no dedicated opl on the board which means that FM duties are assumed by the dream/crystal 9233 chip which produces a very weird result - it is using wavetable to emulate FM sounds... …

yeah... the game is something like 15~20fps? I often wished for a patch to bring it at least to 30~35fps , it would be way more enjoyable on capable systems

well on github there is all the ingo you need if you build it you use UNISOUND to initialize the AWE64 and select an irrelevant address for the CQM - leaving $388 for the extra opl3 you will build that's how AWE64 Legacy does things AFAIK

the CT4520 cannot support a yamaha opl3 - the AWE64 LEGACY is designed from the ground up to include all it's extra features you can add an opl3 with wires etc but in the end you would end up building an equivalent to an adlib wired to an existing pcb just get an adlib clone and use it alongside the …

This mod essentially turns a suitable mt32 to a cm32l , I doubt there are compatibility issues different from a real cm32l it is nice to get the extra sfx and screen if you have a new-version mt32 , can't see any drawbacks to it (except the modification work needed)

Turns out the 2nd unit is just a 2nd gen mt32 without the headphone jack. Apparently they exist.

^ apparently it does have a replaced xtal to achieve midi baud so I guess it works as an UART interface (just like the ones on SB cards)

[...] Is this really just a dtk serial port card with a custom board that plugs into the dip sockets? It does seem to be the case, that extra board is probably to add isolation for the midi input I would classify it along the other lpt/serial midi interfaces that were available. It is probably only …

I like it, great work!!! really love the setup utility looks - faux BIOS-like 😀 do not be disheartened, it is normal that a XT-related piece of kit does not get much love quickly since the whole "XT scene" is not that popular with few (but dedicated!) followers...

Be careful to set different address on AWE card, probably 300 If both cards try to use port 330 it won't work Maybe you had AWE also using port330 the whole time? because if that was the case then you would get the "interface found but unable to determine irq" error
