[Coco] COCO POKE CHEATS & DISK EDIT CHEATS!

Thanks for that warning, Art.

I've always had a question about this, and your reply below reminded me.  Does the warning about a 12V charge destroying the CPU apply ONLY to the Coco1?

Would a Coco2 or 3 be susceptible to this condition?

I'm certain it is a bad idea to remove/plug in a cartridge on any running Coco, but I am interested in the likelihood of destroying a CPU.

Thanks!
John

With regard to your entry for the Canyon Climber cartridge...

It is not a good idea to insert or remove a cartridge with the power on, even if you have disabled the autostart with pokes as you indicate.  (The pokes disable the cartridge FIRQ in the PIA.)  These pokes do nothing to protect against the 12V line (on the CoCo 1 only) from shorting to a line that wants only 5V and probably blowing the 6809 if the cartridge is inserted just a little crooked.  Fortunately, Tandy made one of the cartridge lands a little shorter than the others to make this unlikely with Tandy cartridges, but 3rd party cartridges are generally not so forgiving.  I speak from sad experience in this regard.
