1) Machine with a 'turbo' switch, running in non-turbo mode?

2) Software "slow down" utility? (I remember these, but can't for the life 
of me remember the name of any of them!)

3) Underclock the system board? (I certainly did this on a 486 years ago, 
replacing its 33MHz oscillator with a 3.x MHz, with no apparent ill-effects 
with regards to stability)
