Heck, I can probably remember most of the PPU overlay names and what they
did. The first time I ever heard the term "virus" in relation to computer
software was when some idiot submitted a job that repeated called RSJ.
For a time, I worked on a transaction system on the Cybers, where system
calls were done exclusively with XJ instructions and not RA+1 stores. Made
much more sense when your system was CMTR based--and on this particular
system (swaps were done to ECS), exactly where RA was for any given job
could change very rapidly. But then, 7000 SCOPE did much the same thing,
didn't it?
