I read this article in Monitoring Times July 1999 ( p. 70) shortly after I upgraded to 333MHz and WIN98 Second Edition:

Beastly upgrades!

As a writer on weather satellite matters I do spend a quite unreasonable amount of time not only monitoring weather satellites but on testing new software. ...............The current total is five [ computers] - ranging from a 386 .... up to my latest Pentium Pro 3.

When I took delivery of a PP3 in late March, this represented a considerable upgrade from my 200 MHz Cyrix clone. The latter had produced image synchronization problems that I suspect resulted from the (non-Intel) processor's architecture.

The new computer, however, proved a disaster, crashing several times a day, even while decoding automatic picture transmission (APT). The supplier replaced it after a week of tests, but the replacement behaved similarly. A further replacement simply would not work, so a full refund was agreed. Another PP3 computer was bought from a different national supplier and has proved faultless.

The same software has therefore performed differently on three separate, "compatible" computers, leading me to the conclusion that one has to be very careful when judging the cause of software "problems".
