Now the sad news :cry: It looks like the CPU has died :cry:

I tried my other booster I made up, that one works, the booster GAL is OK and its getting the clock, but just a white screen.. So looks like 40MHz is a PLCC CPU killer :(

So I will order some likely 32MHz ones on Monday and try again... :roll:

Nope, not at all.

I just unsoldered the CPU and tried in MB direct and it worked.. So big :WTF: There.. unless the heat from the heat gun "fixed it".. Doubt it...

Will plug the other booster in, and will leave that running.. but not here weekends, so likely leave running all day Monday and see if same thing happens...

I even heated this other booster CPU up with heatgun, can't touch it its burning hot and machine still running :shrug:

Just a random suggestion.

Is it possible that the board is warping underneath the cpu after it's been on load and warmed up? thus breaking some of the contacts onto the socket on the MB.?
If it ain't broke, test it to Destruction.

Its possible a solder connection has broke... I mean the CPU ran direct in the MB... but I did check bus activity before I took it out, and CPU did put /AS low several times and DTACK issued also..

I've been heating up my second board a lot.. but nothings died and its almost smoking now :lol: Even so, the CPU hardly gets warm anyway. The GAL actually gets a lot hotter than the CPU.

I did try pushing down on the CPU pretty hard before I removed the CPU from the board...Though if it was a bad connection on the board, its take like 30+ hours to show up.

30 hours and a pig to find, especially how that CPU is mounted to the board i bet.

I work in hot boiler houses and component failure due to heat is a big thing for me.

You'll sort it I'm sure....

(Unlike me and the Mega, having a break, lol)

I left it running overnight, and will leave it running today also as much as possible. Currently its at loop 261... The previous board got to around loop 120.. Though it had been running several hours for the past week before that...

So I am leaning towards its more PCB related than CPU...
