RE: TI-H: "Bootstraped - Dumb calc"

That is so far beyond illegal I won't even go into it.  Also, why would you want to do it that way?  try piggybacking a header onto the ROM so that you can have both without breaking the laws.  After all, there's very little stopping you from installing an 83 ROM at that point, if you're resourceful enough...

I'm the first person ever to bootstrap their calc over a network.  Using
the internal ROM, I blowtorched it off and soldered a header in.  Then I
made a circut on a breadboard with an AVR...  You turn on the calc.  The
avr says hello and gets hold of the server (mac) downloads the selected rom
on the server, loads it into SRAM, then resets the internal Z80 chip and
then the calc started up!  It crashed after working with it since my
breadboard was shorting out but it worked!  I havn't tried it yet, but if I
can find an 82 I will dump its rom into it.  It won't work, but it would be
interesting...

So this will be a feature on my network.  The hub will hold a rom of each
calc and when the calc asks for the rom it sends it and then the calc runs
the ASM.

This isn't just for making something neat.  Once we have the display
driver, memory, and link port routines down we can make calcs that play
only games, or one program.  This would make games a whole lot faster!

After someone does taht I can incorporate the design into the EIII.  Then
you would get the interface from the EIII and the EIII would ask you which
program to run.  If you decide to run TIROM then it would look like a
normal calc.  When doing this we could make a *patch* that someone would
apply to their calc.  Then we could incorporate "goodies" into the TI
interface...
