fx-7000G

Boots the Casio fx-7000G to its RUN screen showing 0 on the 96x64 dot-matrix LCD. Type on the on-screen fx-7000G keyboard, or use your physical keyboard: digits, . , + − × ÷, ^ (power), Enter = EXE, Backspace = DEL, Esc = AC, and g = Graph, m = MODE. Do a calculation and press EXE. For a graph, press Graph then a function key (sin, cos, tan, log, ln, √, x², 1/x) to plot Y = f(x) across the screen. Open the debugger to single-step the Casio-fx microprogram, read and write the calculator registers and 1KB RAM (dot-matrix VRAM + numeric registers), set breakpoints and RAM write-watchpoints. This is a functional model: the HD61913 mask ROM is undumped, so there is no vendor ROM.
