<\/a><\/figure>\n\n\n\nThis is equipped with a 40MHz 68040.<\/p>\n\n\n\n
So upgrade is easy. you need to find the roms for the Apollo 4040-060 rom and program it to a 27C010 prom. (or I used a 27C1001) I will not include the files here but are not hard to find on the interwebz<\/p>\n\n\n\n
Remove the 68040 cpu, it is in a socket. I have heard SOME boards have a 040 socket only in that case you need to add headers to fit the 060. I will not include instructions for that here.<\/p>\n\n\n\n
Also remove the 2 (sometimes more) jumpers you see close to the cpu, it is marked “DO NOT REMOVE” but here do that. instead you add a voltageregulator similiar to one you need to use for a Apollo 1240 when upgrading to 060. Add a jumper for the “060” location and move the jumper close to the SIMM socket from 040 to 060.<\/p>\n\n\n\n
Flip the board.<\/p>\n\n\n\n Under the “060” socket there is a empty pad marked 060-R0 put a 0 Ohm resistor there.<\/p>\n\n\n\n also make sure “CLKEN” is connected to “GND” and remove the resistor below the CLKEN resistors.<\/p>\n\n\n\n And change the 80MHz oscillator to a 50MHz. and you are DONE!..<\/p>\n\n\n\n (you need to install 68060.library etc etc yadda yadda as usual)<\/p>\n\n\n\n <\/p>\n\n\n\n OVERCLOCKING.<\/p>\n\n\n\n To overclock the board: move the CLKEN resistor to the pad to the right of it.<\/p>\n\n\n\n move the “040\/060” jumper to the 040 mode. put a oscillator like a 80MHz and it will be 80MHz.<\/p>\n\n\n\n REMEMBER this will HALF the memoryspeed!<\/p>\n\n\n\n<\/a><\/figure>\n\n\n\n<\/a><\/figure>\n\n\n\n
