Re: PET diagnostics

I may be able to include those diagnostics (or similar) in my cbm-edit-rom project if someone can extract the code from the original rom set (there is a bit of room if we use a 4K edit rom). It could probably even be called with a check for a key on bootup, rather than grounding a pin.

Hi Rob,
the used ROM set should be basic 1 according to
http://zimmers.net/anonftp/pub/cbm/firmware/computers/pet/README.also
I found a youtube video that claims to show 'A successful pass of the
diagnostic rom': http://www.youtube.com/watch?v=l5E8mpfBbZg
Unfortunately no further information :(
Could you take a look at the documentation and dongles ?
