- for you interest, the 75MHz machine uses a clock double DX2-33 running
- at 37.5MHz to get the 75MHz internal speed. The motherboard is a 50Mhz
- motherboard so all that logic is spec-ed at that speed (i.e. its not
- an uprated motherboard as well). to cope with the processor heat
- they have attached a mini fan onto the top of the 486!
