Spencer Chase (and indeed our Listmeister Robbie) advises :

"If you have an application you want to run, especially a small market
item, you may just have to set up an environment for it.  It is a big
job to get a program to work on one machine.  (snip)  Just buy a cheap
old computer that still works and dedicate it to the application."

I considered doing this to overcome my Encore/XP compatibility problem,
but my ancient little house is already stuffed to capacity with several
thousand piano rolls, sheet music, hundreds of LPs and CDs, piano,
keyboard, computer, printers, scanners, tape recorders, synthesiser,
etc., etc., with all the associated cables snaking everywhere.  Were
I to install another computer to run just one application my
long-suffering but musically unaware wife Mary, who yearns to lead
a more conventional life of domestic bliss, would probably drag me off
to the divorce court.

I purchased my new XP computer because I was attracted to the 19"
monitor, 80 GB hard drive and 512 MB RAM which it offered.  (I work
with music files, some of which can be huge.)  Now that all the program
incompatibility snags have been ironed out there is no need for a
second PC -- I probably chose the most expensive workaround but Mary
and I are still on speaking terms.
