Wow! All this is extremely interesting, but not practical for the more normal BASIC programmer. However, TI BASIC PLUS (TIB+) includes the full 32 sprite capability (thanks to Mark Wills) using CALL's to assembly language routines. It can be implemented using E/A, Mini Memory, or a GRAM device or a disk controller with the Myarc disk controller DSR that includes TI BASIC support. Currently the best solutions are an 80K MG GramKracker or HSGPL card, and hopefully, the FinalGROM99 will provide the ultimate solution. These three versions will allow the user to write TI BASIC programs of up to 40K and more with GROM base switching. Hopefully this is enough to "wet the appetites" of some of the would be BASIC programmers out there.
Bill, could you please start a thread here in the Development forum for TIB+ discussions? I have been intrigued by this project for at least a decade now, and I am eager to hear your progress, how your hardware issues turned out, and if you have plans on implementing TIB+ somehow in conjunction with the FG99 cardridge. It's good to see you contributing here, my friend. I miss our conversations.
