there is absolutly no reason, why the heatsink of any VG systems based on the LM78xx voltage regulator should be modified in its size! don't worry about, those systems runs since almost 20 years now, and nothing ever happen!

hmm - now the pc engine has its casing back on - i`ve been testing the console out and its all working fine - but the plastic over the heatsink gets damned HOT.

Fairenuff the heatsink gets very hot - but the console casing shouldnt?? seems a bit dangerous.
This is after about 20-30mins, it becomes untouchably hot. This cant be normal surely?

White pc engine - original psu.

(my coregrafx casing never gets crazy hot like this)

Yeah, that sounds like a problem.

Wait a second...am I hearing this right? The PCE uses TTL circuitry? Wtf, no wonder it requires such a high amperage adapter...I guess TTL is cheaper than the low-drain CMOS alternatives, especially for the time, but damn...at 3mA per gate...*shudder*

sorry to drag this thread on... but any guesses at what might be the causing the excess heat? dodgy capactitors? wonky regulator?

dont want it to catch fire/melt on me
