HP-41CY re-initialization ROM

[Jurgen Keller]

In the meantime I also created a HP-41CY eraser module which overwrites both RAM banks of the 41CY, including the operating system (if not write protected). I implemented it also as a take-over ROM. The effect is drastic: you usually cannot turn on the 41CY anymore. If you plug in 4 x 8K ROMs into the ports it works again. This is a good test for the HP-41CY initialization module. Fortunately, it passed!



I've also created a document where I described my findings related to the re-initialization process. You'll find it in the GitHub repository.
