RE: C-128 and Jeri board

I really do understand. You don't want to lose the
ability to run C-128 software. I would like to keep
that compatibility as well.

Since it is unclear at this time whether and to what
degree Jeri's board will be compatible with the C-128,
there is no answer to that question. We'll have to
wait and see what Jeri comes out of her workshop with.
It's enough for me to know that she is aware of this

As to the User Port, I ASSUME (I suppose, I guess)
Jeri will emulate a 6526 at the Geek-port as well as
whatever else she feels like putting there. That means
that, given the right connector, you can do anything
there that you could do on the User Port.

Other things that might be fun to have at the
Geek-port would be:

all critical system signals
+/- 12v for powering external devices
alternate video signal(s)
analog input for sound/video digitizing
high-speed a/d converter for the analog input
Both NMI and IRQ
IEE signals for connecting PET peripherals
Alternate clock inputs to feed the system hardware
(and generally wreak havok)

Well, just a few ideas. Take 'em fer what they're
worth  ;)
