Casio Fx 7000Gb Manual5/24/2023 ![]() ![]() ![]() I bought this calculator in 2004 at Cash Converters, and even then, it was ancient for its time. This is normally difficult to achieve in 422 bytes, but after hacking its memory, I was able to use the variable register space as well. I made some games, learned how the memory space was organised, and wrote a program for displaying the Mandelbrot set. Just for fun, I wrote a program for the delta-y transformation as this is something very easy to remember and it took just a few minutes. It is very easy to program this, as the language would be second nature to any programmer. ![]() For its time, it had a powerful programming language as it could also manage array-type memories, and pointers. The flow of program execution is very important and for that, you have the familiar "GOTO" command, as one would find in the BASIC language. The main program can then call these routines when required. You could have ten independent programs in each storage space, or one main program with nine subroutines. The program area is divided into ten sections P0 through P9. The programming storage space consists of a maximum of 422 steps, where each step occupies a byte of memory. The system architecture is Harvard based. The programming model is formula based with a mix of mnemonics for the conditional jumps and glyph symbols for variable assignment.
