retro-computing m100 basic
Notoriously S.L.O.W BASIC
This week, I spent some time writing code for my m100. On my list of things to do with the little machine, was to write a disassembler. In order to disassemble memory, it helps to know what's there, so I decided to write a memory dump utility first.

Programming the PAL-1 Using the Keypad
A video walking the user through the process of programming the PAL-1 using the keypad. It begins with a short overview of the PAL-1, then covers prelims like where the START program resides in ROM, how to set up the IRQ and NMI vectors, how to view the Accumulator contents, how to enter a program, where it should go, and how to run it normally and single step.
Enjoy!
