Try ticalc.org

accessing the ROM is done with ROM_CALL( or call (see the ti-85.h file
for more info on this) and RAM is accessed by ld a,value \ ld
$memorylocation,a

See the file TI-RAM.TXT

Look for the file compiler.zip on ticalc.org(i think that is the file
name) but the maximum size of the program will be a little more than
1000 characters because compiler uses a LIST varible

don't know that one.

video memory is the memory used by the video card in the TI-85 and i
guess would be the memroy that is normally accessed when you use the
TI-OS but when programming the programmer would normally use text memory
and registers for storing information.
