RE: C128D Question

Ah, just saw this, thanks for the reply. Sounds like the plastic case ones were the original designs, I wonder when they were released and for how long.  If they re-laid out the PCB and weren't watching things very closely, especially like sharing ground with the drives, that would explain the complaints I have heard about increased video noise.

> Were there 128D's that were made with the original PCB in the bigger case or was it just released as  the 2nd rev of the PCB board?  (The big holes in the middle of the production 128 board were there to accommodate the D chassis.)

Afaik there were two versions of the C128D released, one in a plastic
case with the standard PCB and 1571 electronics on a seperate board,
and one later model (usually called the C128DCR) with a smaller PCB
which included the 1571 electronics and 64K VDC RAM and the 8580 SID.

The former model is more common in Europe, the latter in the US iirc.

> Are these "real" 128D's thought of any differently than the production ones? Are they curiosities, collectors items or just old trash?

Judging by the money people have paid for C64 and C364 prototypes all
Comodore prototypes are collectors' items.
