   A while back I borrowed from a friend of mine the Mini-Mem
cartridge for the TI 99/4A in order to familiarize myself with
the 9900 assembly language. I've run into one particular problem
that I hope someone out there in netland may be able to answer.
  The problem is this. I want to use the KSCAN utility in order
to input keystrokes and display them on the screen. Seems simple
enough, but there is a hitch. The Easy Bug Debugger option on
the Mini-Mem reserves memory locations >8730-8FFF. Any attempt
to modify the contents of those addresses is unsuccessful. Un-
fortunately, the KSCAN utility uses >8375 to store the ASCII code
of the key pressed and >837C to store the status bit which in-
dicates a key was depressed. Well, needless to say the Easy Bug
Debugger has buggered up that whole process. What can I do?????
