I attempted to use it on my 128.
Without a cartridge plugged into it, the 128 would come up part way -- in 128
mode. It would have the gray backgrouna and green border and a screen largely
full of "_at_"s.
With a cartridge plugged in, the screen stayed black when I turned the power on.
It certainly seemed about the right size for a 64 cartridge, but it doesn't
work that way. Also, the passthru plug is a teeny big too large to easily get
a cartridge to attach to it.
