Program development director C. Needham gives us a clue as to the innards of the program. "Actually it is quite simple in concept. There are several BIOS and library routines that return the date when called. This obviates the necessity of resetting the system date. We simply interrupt these software calls and send the dates being scanned to the program undergoing testing. We have a simple AI feature that wraps each program and learns its program methodology thus automating repeated calls to the program over a range of dates. In order to maintain data integrity we interrupt all disk read/write system calls. No permanent data is modified. Once the program being tested is validated (either immune or terminal) the waste virtual data is either flushed to disk for inspection by the user or purged."

E. Gold contributed and interesting insight into the associated device tester. "It was a little tricky automating the EPROM reader. But once we developed the universal EPROM scavenger we were able to emulate any hardware device be it toaster or chemical relay value on-board the computer in simulation without subjecting the hardware to actual date increment. This avoids any awkward moments with our customers that might have occurred if we had smoked their production plants by prematurely sending them into Millennium 2000 crash and burn. Now we can animate a nice graphic on the screen and all have a good laugh rather than run for the phone and our attorney."
