(as an aside.. an EA#5 loader from TI BASIC. How this would have killed back in the day.... ;) )

 

Oh gawd, yes! Could you imagine being able to go back into time, say 1983, then walking into an anonymous TI-User group in some unknown city... then pulling that little piece of wizardry out of your diskette case and showing it off? I can only imagine the reaction.

STARTBUFFER could be anywhere. So you include the text at the front of the buffer. This way you can look at VDP ram with Classic99's debugger to find out where the buffer actually is. If you do any CALL FILES other than 3 it will be in a different location. But none of that matters - when a program runs under playground it figures out where where the embedded code is. If you created a program with a standard TI disc controller with CALL FILES(3) and then load it with a CF7 it will be in a different location in VDP, but all that gets taken care of by the playground loader.

In light of post #48 and what I think you just said, a program of >800 bytes will be loaded in the topmost part of VRAM to include the highest available VRAM location stored in >8370. If that is the case, there is surely some way to discover that last location so that >8370 can be restored without the convoluted checking we have been implementing in @Gazoo’s “Programing challenge” thread.

Lee provided the insight needed to figure out how to restore the value at >8370.

Below is the first program from post #48 mentioned above:

R0 points to the 1st byte in BUFFER. When we set it up as described in post #48 we wanted to reserve >0772 bytes for the buffer, so if you add >0771 to R0 it will point to the highest available address in VDP ram, which just happens to be the number that was in >8370. You'll see the 2 lines of code needed to restore >8370

 

N.B. The buffer must be an even number of bytes. Either playground or the assembler does some rounding and the address will be off by a byte if your buffer is an odd number of bytes in length.

 

This works with any CALL FILES in BASIC with a ti controller. These all give an odd number in >8370. If the CF7 needs 8 more bytes there should be no problem, however if for some reason it gives an even number in >8370, then it is possible that the value will be off by one byte. (I have no way to test this.)

 

(edit) Just to recap: once embedded, the last byte of BUFFER will be the last byte of the BASIC program. When you load a BASIC program, the last byte of the program is at the highest available address in VDP ram. Since we know the address of the start of BUFFER and the length it is easy to find the highest available address and plug it into >8370.

Bravo! :thumbsup: :thumbsup: :thumbsup:

The CF7 gives an odd number exactly 8 bytes lower than the TI, viz., >37CF for max of 3 files. BwG gives 2 bytes lower than TI: >37D5.

BASGRMLOAD.dsk

 

Can you try this disk, Lee? It apparently works in classic99 with the TI Disk Controller code banked in, so it should work on a real TI.

I finally followed Senior Falcon's directions from his original post coupling it with the newest update and it actually worked! (Imagine that :) )

And if your's and SeniorBirdGuy's assumptions are correct, this should work. The disk contains all the work files and the GROMLOAD program file. You'll have to use another disk with the Ubergrom Grom dump to reload the cart. Thanks Guys!

... and of course the next thing to create is a 90k disk that loads BOOT with no cart and a nice EA5-program-menu configured. Put the disk in any TI with 32k memory and run a TI BASIC program that loads and runs a menu of assembly programs would be cool!

 

BASICLOAD is 10 sectors and BOOT is 50 sectors, so subtract 60 sectors from 358 and you get 298 sectors.

 

So here's the challenge - submit a disk with the BOOT program and a bunch of EA5 programs configured in BOOT. There should be 10 free sectors on the disk to put the BASICLOAD program.

 

Won't that be a cool demo in November! ;)

It works! :-o

 

It still doesn't pass the GROM checker; but, BASICLOAD loads and runs GROMLOAD. I can't get a compressed EA3 file to run from option B (TIW/EA); but, again, without a pass by the GROM checker, I shouldn’t complain.

@Lee and Dragonstomper I am truly amazed by your skills and tenacity towards Gazoo's challenge. I am so glad that he could see his last challenge accomplished thanks to your help. I think that what you 3 did is holywood material. Was software your hobby or did you work as software developers during your life? You seem to be pros,

Yes to both parts of your question—though I am not sure I would put myself in the same league as Harry (@senior_falcon) even though I, quite possibly, have been at the software game longer than he. There are quite a few similarly able folks on this forum, by the way—in hardware as well as software.

@Lee and @Dragonstomper and any developer in these wonderful forums, would you feel like sharing some software dev experiences with us in some new threads that we can read and learn from you. I mean real life experiences of what you did during your lifetime, to be shared and stored digitally for many years to come. I am sure you all made great things in your lifetime and not just a boring 9 to 5 job. Were you part of a team writing games on the TI? or some other popular console ? The challenges, the failures, the long hours and finally the successes. We hear about Wozniac, Jobs and Gates but I am sure the real people behind the great successes are the soldiers like you "The unsung heroes". Thanks for your time, genius and persistence to ensure you leave this world a little better than you found it. I am 48 and wrote a few basic applications for the TI back 30 years ago but nothing compared to the wonder I am seeing here. Keep it up.
