What you have to do is make sure you have one or two backup hardware packages, because when the computer breaks, you won't be able to buy one that works. (Just try to find a motherboard with ISA slots today!) And with custom plugin boards, it is kinda too late to have them fabbed when the system is already down. And fire it up once a year to make sure it still runs. That may not guarantee that you can recover, but it vastly increases your chances. And when you put the reserve system into service, it is time to expedite developing a replacement! For PC systems, the big hurdle is that old 16-bit systems allowed programs to do I/O to ISA bus peripherals without kernel programming, device drivers and OS hooks. When you "modernize" that ability is lost, and you have to rebuild with much more complicated programming. -- Lars Poulsen - an old geek in Santa Barbara, California
