Didn’t know that: hard to believe they managed to pull off additive synthesis on an 8096. That’s impressive
I had a later Kawai K5000 which added short PCM samples for attack transients. That thing was crazy, foolishly gave it away more than a decade ago
I received a final software update from Kawai and had to open it to install the EPROMs, which is how I saw it. It was a very cool synth - very high quality feeling.
I also had a K5000 and was so stupid to sell it over a decade ago; no way to find one again now at less than 5 times that money.
Intel 8097 in the Roland W30, and I think also the S50.
The later S550 is the unit I was fixing mentioned in another comment, that one was a 8095
