What is this Pandora project I keep hearing about?

Also, I just realized something. We have said this calculator needs to do math but it also needs to be able to graph too.

With the idea about using a TI product, who knows. Maybe we could show them how to use there technology correctly :P

i extremely doubt TI will have problems with us forking over cash for their profit. a consumer would have to do something pretty bad to be shunned from the business of a corporation..

We should get KermM to help with us maybe.  Since he has an EE major I think.  But I think first things first, decide on the chips to use.

I highly suggest figuring out exactly what the specifications are in terms of processors, chip sets, etc. and get the software written first.

Imo, the case should be last.  Spiff it up when it is done.  In the opening states, it can look like crap :P

For the Z80 project, definitely use an eZ80 :)

I wonder if we could use existing z80 code for the ez80, like no porting over (besides recompiling it... I think *shrug*)

To be perfectly frank, the case basically has to come last. Yes, we can have designs but the building needs to be last because we have to fit the design to the insides. If we build first then we limit what we can use.

Probably not, since a bunch of the equivalents right now only work with the calc, and it's ports.

It is completely backwards compatible, so we can use existing z80 code (but we would still have to port it to not use or reference TI-OS at all, of course)

Well, if it's a real z80, then we should, maybe with really minor changes.

remember though, all of the asm written will be for a monochrome 96x64 (probably wrong :P) resolution and we will want to rewrite most stuff for the better specs.   ;) direct portability would be nice, of course.

I don't think we should make the calc with portability in mind.  It would be much better on the new calc, anyway.
