I've never had a IIfx,

However, mcdermd got one not too long ago. he was having issues, forget what the issue was… (maybe he can chime in)

I suggested he pop out the fpu and cpu, and re inserting them and it started working,

The IIfx makes alot of heat, expansion and contraction, FPU/CPU socketed, Ahem appleIII

Its the fastest 030 apple ever sold, that is why I want one.

Also there is some radial caps on there, I do not see any tantalum caps.
