I've a //c  w/ 1 M Zram Ultra II and purchased an 8 Mhz Zip for it
when I was designated club newsletter co-editor for '92. When I ran
PI! 4 I'd borrowed from the outgoing editor, I found it locked up and
wouldn't run after I'd installed the Zip.
 
TimeWorks claimed it was a fault in the Zip design as PI! v3 worked
fine. Zip claimed TimeWorks screwed up Interrupt programming when
they upgraded v3 to v4, but since the chip was under warranty, they
offered to take it back and send me a newer one that "should" work.
It took a long time for the new chip to return; Zip claimed the chip
manufacturer had production problems.
 
Picked up PI! 4 from a deserting member; it works. I do wonder,
though, if TimeWorks didn't disable the Zip in the programming....
screen redraws _DRIVE_ME_C-R-A-Z-Y!!_ They are still SO S-L-O-W!
Aaack!
