RE: PET 2001 Fix....WAS: Will pay good money for NON working PET 2001 motherboard.

When we included the Monitor program in the TED (Plus4, etc) that allowed disassembly and display of memory the head of Commodore England sent a Telex saying that we had created the perfect machine for software piracy.

MY Telex reply was "Thank you".

Ultimately useless, yes; but for 90% or more of the initial
purchasers, a sufficient roadblock.

If the CPU can read a byte, a determined engineer can read that byte.
Simple protections merely keep out the casually curious.
