Yeah it's a zip chip alright - same packaging as the 4Mhz one I bought
in the mid 80's. Even has some of the same small bumps under the epoxy
on the flip sde as the 4MHz one. The sticker is gold with zip8000 on
it.

Agreed - I was kind of suprised that it would still function fine in
slow mode.

Right .. Fast mode is the default and pressing ESC drops it to slow
mode. It behaves the same way wether or not ESC is pressed. I also
tried the chip in a IIe - same thing.


My 4Mhz chip on the other hand doesn't work at all anymore - it only
lasted a few years or so and that was a replacement for the original
dud they sent me in the first place.
