Alan Pratt (@atari) poste one program a while back.

As far as I recall, it made the BUERR vector point to the same place,
the RESET vector points to and then started to write 0L to any RAM
adress from the first longword behind the program code (start of BSS?)
up to 4M+1. Writing to this adress will cause a BUSERR, and BUSERR
points to the coldstart routine (pointed to by RESET)...

Any virus (or ramdisk) will die fromm the NULLs :-)

lethal overdose of brick wall, taken while under the influence of a
Ferrari and a bottle of tequila. (Douglas Adams; the long dark teatime...)
