A way to freeze a PET

Hallo allemaal,

Maybe I'm telling nothing news at all but I found a way to freeze my 8296D
completely by accident. In order to find a programming error in the past I
let some programs end up with 4 zeros at the end of the PRG instead of the
usual three and changed the transfer routine a bit. After finding the
original error I restored the transfer routine. But yesterday I found out I
made an error there as well. Instead of sending the last byte, I sent the
byte next to it. That was no problem with a PRG which had 4 zeros at the end
but was with new ones ie. those with only three zeros. The byte actually
sent was $01 thus making $00 $00 $01 as the last three bytes. 

What makes things weird is that the CBM displays 'ready.' and then freezes.
I can accept a situation where the screen shows 'loading' and then freezes
or a program that won't start or behaves weird but displaying 'ready.' and
then nothing ????

What I do miss in these kind of occasions is the RUN/STOP-RESTORE
combination of the C64.
