If you're interested in writing assembler pgms for these
computers, I have a DOS executable which will turn the
*.lst file produced by ASM7 (available at WHTech) into a
*.b74 file in the format:

100 DATA n,n,n,n,n,n,n,n,n,n
110 DATA ...
...
190 ! 100 bytes (or whatever)

The pgm can then be loaded into memory with a POKE loop
(usually after reserving space with GETMEM) & run with EXEC.

The CC40 User Guide has more info, and there is a detailed
discussion of file formats (& much more) in the CC40 EA Tech-
nical Reference Manual, both available at WHTech. TI-74 &
CC40 file formats are identical; ROM routine addresses are'nt,
unfortunately. There is also a good discussion of low-level I/O
in the TI-95 Programming Guide, which pertains to the three
machines.

If interested I'll email you the file - It's about 40K, and will run on
a DOS machine, and also works on VPC 2007, or at least it does
on mine.

Hard to believe I'm the only one who writes code for these interesting
old computers!

That is interesting. I'm surprised Curtis and MutantCamel haven't chimed in yet. I'm definitely interested in this, as all things TI are interesting to me.

Definitely interested!

Hadn't had a chance to peruse all the recent postings. Do most of my surfing at work and for some reason, the boss wants me to be somewhat productive in order to get a paycheck! Rather cheeky if you ask me, which you didn't.

I'll pm you with my email address.

I definitely need to drag out my EA cartridge and get playing with that again. Just as soon as I get finished with school, Comptia A+ exam, wife's honey-do's, walk the dog...

Ya know, used to be 36 hours in a day was more than sufficient, but not anymore!

Fear not, I'm still mired in computer pathologies. Let me know when
you come up for air. Who knows, maybe I'll have some of this junk
working by then...

Spring break next week! Start off this weekend by making a pilgrimage to DFW and Fry's!!!! Also a couple of vintage electronics/hamfests there also.

Too bad it's not either first or third Saturday, then I'd have a trifecta and catch the under-the-bridge show also! Ah well, can't have everything.
