VIC was not a great display adapter even by 1980's standards VIC-II was much better, but it was already used in the best selling computer of the era. I think other companies would not see any space for competing against that with the same video chip. SID: see VIC-II reasoning. I think it also applies to the Amiga chipsets, imho. > > At some point in time the MOS/CSG products must had stopped being > competitive in the semiconductor market. they were basically only producing very specialized chipsets for their products as soon as the C64 started being a good selling machine. Btw, I have a PCB of some device (it has a midi interface, I can't tell much more about it) that happened to use MOS general purpose TTL clones (like the 7406 equivalent and others that were found on some C64 boards too). So in some cases, those chips were sold to other companies. FrankReceived on 2020-05-30 00:33:05
