You can build it yourself using the *`make_po.sh`* Bash script under Linux or OSX. It should be trivial to write an approximate BAT or Powershell for Windows, if that is what you are using. Note - You need to edit the following lines in the *make_bootable* script:

# About the code
## Historical Context:
This grew out of a much simpler memory tester I had thrown together earlier in 2015. At one point, I started working with an Apple II hardware vendor to include their feedback as feature enhancements which eventually caused a large rewrite to support a more robust configuration. There are some hacks and magic sprinkled in, but I tried to keep it pretty sane.
Some of the code paths for the testing engine are a bit generic, at the expense of speed, but to make the code more managable (for me!) Other parts are, perhaps, oddly organize but with a mind on keeping overall test loops relatively tight.
Overall, this program favors configurability and reusable code, over speed. There's also not much thought to stability, but I wanted to allow the user to try to test their RAM as they see fit.
## Technical Context:
Large portions of this program are written in one of the two cpu modes:
**m=1** (short) **x=0** (long)
_or_
**m=0** (long) **x=0** (long)
The 8-bit test modes, in particular, are written with a short accumulator, but long index registers. This way it can easily scan a bank of memory using the X register from 0000 to FFFF. Likewise, when running 16-bit test modes, we write 16 bit values using a long accumulator, and still using long index registers. However, we also increment or decrement by two, since it writes two bytes at a time with a long accumulator.
