I was told by the initiator and sponsor of this project that the parts were extremely difficult to source and come mainly from China. A significant amount of time and money was invested. He actually had several other daughterboards (including SCC-1 and SCC-1A versions) and several ISA soundcards made. Very impressive stuff, well designed too, with some unique features (notice the SPDIF output pins in the pictures). All in limited numbers, so rather exclusive.

Yeah we need to confirm whether it's a simple rompler, or a full reproduction of LA Synthesis capabilities.

If the former, then with all due respect it won't be worth much. If the latter, then Yes Please.

well we can see it has 32kb of dram (4 x 64kbx1, so 32kb).

original mt32 has 2 banks of 32kb ram.

1 32kb is for the BOSS chip, the other 32kb is for the intel mc96.

its funny to see those old intel embedded mcs-96 / 8095 cpus.

Those are actually as well on the original MT32, the LAPC-I and probably other LA32 based devices.

I don't know how effective or dependable are these so-called LA32 daughterboards. This is the first time hearing of such thing.

I'm not really optimistic about it when it comes to compatibility too. Roland MT-32 ROMs are still copyrighted, and the above boards must be an enthusiast created ones in his spare time.

Anyway, he should played off Sierra adventure games instead, like King's Quest V or something, to show off the capabilities of that card.
If it supports CM-32L roms, Bitmap Brothers' GODS game is one of the few games that require this to sound correctly.

For me, the gold standard to listen to is either the easier to find real LA capable modules - MT-32, CM-32L, CM-64 and CM-500 (of course, problem is getting a MPU-401 intelligent mode compatible ISA MIDI card - or best is the LAPC-I).
(And also, MUNT in Dosbox.)

There is another video in which the owner plays Gods and King's Quest V: https://www.clous.cz/jamicon-spacestation-386-part2/

Works great! Too bad such a project is destined to be for only handful of boards. Especially since the creator invested so much time in it. And even if it won't be possible to source the chips again, perhaps documentation on how it was done would be nice? Just for educational and hobby purposes. Who knows what other interesting projects would come from it?
