So I'm going to try to bring down the temperature of the cache chips by
adding a fan blowing directly at the CPU module. Hope that helps.

BTW: It seems that the only difference between a DECstation 5000/125 and a
DECstation 5000/120 is the clock speed of the CPU? I have another DS5000
(a 120) which I'm currently cannibalizing for parts since it won't get to
the PROM prompt.

I'm in the process of aquiring another 32 MB for this machine - the auction
on ebay is already won, we just have to arrange for payment and shipping ;-)
So I would end up with 48 MB - this should be enough (my current firewall
machine is a 486DX50 with 32 MB RAM).

       Alex.
