(1) Convert the machine(s) to virtual images.

(2) Host on Linux boxes/generic hardware

(3) Arrange to boot into the app running in the VM

(4) Backup the images regularly

(5) Buy a spare box

The VM image is effectively immortal if hardware fails just buy whatever is cheap & current install Linux and the VM program.

Visible light ~5000 - 7000 Angstroms (1X10-9 m)

7000 -> f = lambda/c -> 4.28275E+14

5000 -> f = lambda/c -> 5.99585E+14

Difference -> 1.713E+14 Hz -> 1.713E5 GHZ

About 171,000 GHZ not 17
