Regarding John Grant's comments on the "How It's Made" TV program.
The somewhat bizarrely attired gentleman demonstrating the marking
piano is Christopher Sierzchula, a remarkably talented young man who
arranged and edited piano rolls and created and edited MIDI files
for the QRS Pianomation System.

Yes, the 5-1/4" floppy disks which programmed the Apple IIe computers
are all still in use today -- "If it's not broke, don't fix it!"

I was able to secure long time insurance in the form of spare parts
back in the 1980s by buying out the old Apple computers from a local
school board when they updated their systems.

John is right about the original program material being out of sync.
QRS was never shown the program before it was aired so when we pointed
out the discrepancy to the Canadian producers they withdrew the
program.
