Not sure what you're looking for here, hardware or

Software. I can reconstruct the hardware I think.
Seems to me any S/W not using CB2 would require _some_
kind of special
hardware, however trivial.
Yes. A connector, 8 resistors and a jack.
At least 2 come to mind, the Petunia, and the MTU 4
voice/16 harmonics
systems for
both PETs and KIM/SYM/AIMs; is one of these what you're thinking of?
I don't recall. If I saw a picture of the original for the PET, I'd
recognize it.
The cheap & dirty method was just a resistor
ladder across the parallel
interface as a D/A converter; might still have one of these & some S/W,
but don't hold your breath, haven't looked at the CBM pile in ages.
That is exactly what I was mentioning below.
Hmmm... just ran across an old ad for an accounting
package for a
KIM/SYM; wouldn't you
have enjoyed being the data entry operator for that? Think I'd prefer
even a Windows
package...
Eeeww.

ObClassic: Does anyone have any software for making music on the PET
with *other* than CB2 sound? I had a buddy with a clip-on user port
music card - it was an 8-bit D-to-A like a Disney Sound Source. The
PET shoved bytes out the user port and they appoximated music. I can't
remember what it was called.
