Nice work :)
I remember writing a memory test utility for a PET! It replaced one of the ROMs, and injected code into screen RAM so it could test ZP and stack. Was a fun experience, having come from a Beeb background!
Loved that thing, it was awesome.
Happy Memories First machine I learned on. But I hated that keyboard
I remember the PET computer. At the time it seemed miraculous.
Nifty machines. I sure hated that keyboard, and weren't they heavy machines!
