Well... Seems that there always has to be problems eh.
:\
First no serial number, now dumper may not work. '

MESSAGE: Using the prgm editor and the instructions that Critor gave me on TI-Planet, I have successfully made the calculator print out the rom

Now I just need to record and hopefully the rom reader can somehow read it...

(typing all that in was a pain... )

The dumping starts at the horizontal cursor position, uses the whole scren and scroll line by line.

So the horizontal blank lines shouldn't be a problem.

Vertical lines might be a problem. I can't remember whether or not it makes each line overlap bytes in ROM. I think that it encodes the starting address on each line, so it probably wouldn't be difficult to modify the dumper to give some sort of less-than-one-screen-line offset if it doesn't already, so that each byte would be shown at multiple vertical positions. Unless the lines are close to the left side where the address is encoded; then that could be a problem.

With all my calculators, my missing lines always seem to go away after some use for some reason. Maybe just playing around with the calc for an hour or two might make one or more lines come back long enough to try a ROM dump.

So your emulator can load all 37 programs required to play Illusiat, but what about matrices? There's 2 matrices you have to type out as well and I think there's no file format for them.

critor, how long do you estimate the video length to be?

From how I did it, the lines began appearing at the bottom of the screen.

We could still figure out what would have been a 81M file format.

81P is just the equivalent of 82P/83P/8XP/85P/86P.
In those formats you have a small header with program size and name, and after that the raw data which has to be written to the RAM.

The 81M file format might be the name ([A], [B] or [C]), size (6x6) then the raw data to write in the appropriate section of RAM.

Great you could make that video so fast!


Unfortunately, seems 30mins weren't enough. Seems your TI-81 is running the dumper slower than mine...

The 4 first charaters on the left encode the ROM address.
The dumping is finished when you alphabetically cross LAAA.


So could you make a last attempt and let the dumping program run for something like a hour?
Thanks.
