Re my previous post about no special adaptor to get Celeron ( Socket 370 ) CPU's in Socket 7 M/boards - Have just got the Dec 99 issue of PC Answers ( UK mag ).
A company called "Evergreen Technologies" have PCI board which can upgrade you to a Celereon 433Mhz & 64Mb RAM cost is UK 289 pounds! - Pro's : easy upgrade, Con's: dosn't use your existing memory, old CPU must be left in ( your system still actually boots up using it! ), compatibility prob's ( ie: it just might work with your m/board/BIOS )
Their verdict: new m/board, CPU, RAM is cheaper.
