I've used the PC 704 machines before - they are 6+ year (probably 7
year) old technology. I understand that you can update them by adding
new processor boards, but I doubt they were even upgradeable to a P2,
let alone a P4.
I worked with several of them - and they all developed problems
recognizing processors, after a couple of years of use.
Oh well - they do make a sturdy table....
