The question is who is the interface for. Is this like the SCB1620 interface to provide
a hard drive to a small system that may not have any other major storage device,

PS: I was reading the 1966 PDP 8 user handbook, I am finding usefull programing
information since they give real detail in I/O devices.
Any ideas on how impliment POWER on fail IRQ and restore?
