Hi mate, i used a positive fixed 3.3 volt regulator TS1084CM-3.3 with current upto 5 amp. and has a dropout of 1.3volts if needed. It is in a TO-263 style case and is perfect for the job. I bought it from maplin electronics online, around £4.00 delivered

Depending on where you live, postage could be higher for delivery. Or you could google the regulator and maybe find it for delivery closer to you

Website is www.maplin.co.uk

Hi yes i fully desoldered the old 040/40mhz cpu, this was kinda hard since the 040 was soldered on both sides of the board. I then installed and soldered in the 060 socket and fitted a revision 6 MC68060RC50 with mask 7E141J. These are the newest 060s which i have heard can run upto 100mhz with PC sdram with suitable heatsink and fan fitted. On a blizzard 1260 i think if you have 50 or 60ns simm you could probbably get 70mhz with good cooling but i dont know wether this would be stable in workbench
