we live as we dream. Alone.
to test my new desolder station ... an Apollo 1240 to 1260 upgrade was started.
original spec:
elbox apollo 68040@33mhz bought in 2000.
mach 131
32mb ram
finished spec
apollo 68060@75mhz
mach131
64mb ram
twin simm sockets
1240 rom removed and upgraded to later version. (fitted in a socket now)
pins added for the voltage reg (jumpered now)
second simm socket added to allow 64mb ram 2x32mb
I'm still waiting for the 68060 socket to arrive so I've had to make do with these upgrades and use the 68040 still.
to do.
remove 68040 cpu
add 68060 cpu socket
fit voltage reg & 68060 cpu
parts used.
68060 75mhz cpu
