Post:

I had thought about the upgrade options. I think that finding a 1 GHz
system as originally shipped would be the best option. I've had bad
experience with upgrade processors. There's not much you can do to
upgrade a 200MHz system. You're still limited by memory speed, disk
speed, and system bus speed. We have good support on campus for DELL
and IBM computers. There still are motherboards shipping with ISA
slots. None of the big name makes, of course. I would hesitate to
give up the local support we now enjoy.

Ideally, I'd like to find a half dozen DELL Optiplex GX110's (1 GHz)
with the optional ISA configuration. They should be selling for about
$200-$300 each nowadays.

Good new year,

This is one occasion where having Apple Macintosh computers is really
paying off. We have some 15 year old machines for special purposes which
just run and run due to their more robust components. I have a fleet of
first generation Power Macs equipped with expensive HiFi Audio Sampling DMA
NuBus boards. If you are using this type of hardware you want to be sure to
have a long lasting host system instead of being forced to replace some
short living technology every few years with a yet incompatible new hard-
and software combination. If you finally find a new PC arrangement with an
ISA card connector I would be surprised if things work right away on the
software level.

Never touch a running system is a good way to save money.... but the system
has to be built to last more than a few years.

Just a side note for potential 2004 educational equippment investors and
probably not a real solution to your problem.

Computer prices on Ebay are really inflated these days. Not a great
benchmark.
