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)

???

Gruss
