There was one version of one of the CBM disk drives (I
think it was the
8252LP) where a 6530 was replaced by a daughtboard containing (I think)
an 6532 + a ROM + TTL glue. I don't know how universal that solution is,
but I guess something could be worked out.
Jep, thats exactly the soulution I was suggesting.
Ans speaking of 6530s, I always wanted to know what
versions have existed/are existing, and where they
have been used.
6530-002 KIM 1 KIM (Keyboard Input Monitor)
6530-003 KIM 1 Autio tape extention for KIM
6530-004 JOLT (I just don't remember the software name)
???
