Admittedly, my first thought is probably far more realistic than I thought upon thinking it...

But my second thought was something along the lines of "is there an open-source assembler? [Ziggurat29 had issues with sdcc [but for an 8080]... Am I gonna have to use a CP/M-based assembler?"

Heh... Then thoughts went to, "BAH! I can use ZAC!"

Yeah, we're talkin: 

1) Write the new SD70 code on my TI-86.

2) Assemble it, under ZAC, on the TI-86

3) Transfer that to compy

4) Convert it somehow to an EPROM image

5) Burn EPROM

LOL.

It makes a heck of a lot of sense, no? Use the tools I know!

(As crazy as it may sound, I *did* actually think of some code I wrote on the TI-86 which could be handy here... what was it? Oh, the flash-programming code... hmmm)

OK, that's a bit ridiculous, assembling code for this on my calculator... But it really made sense at the time!

Heh, maybe that flash-programming bootloader-ROM I mentioned earlier should use TI-Graphlink instead of Zmodem?

*Sigh* brain...
