 |  Re: Another black screen issue - already has heatsink fitted.
I've read about the heatsink to be applied into the Plus/4 almost everywhere since years, and my opinion is that heatsinking a TED or a 8501 absolutely doesn't help in any way: Plus/4 is one of the coldest computers of the era, insomuch as you can check the broken IC simply by testing all of them with your fingers — the hottest is the broken one.
Plus/4 TED or CPU easily break up due to bad electric charges on the connections, especially the joystick ones, especially if you attach/detach joysticks with low quality 9pin/round cable adaptors, just because those ports are directly connected to the TED itself with no shielding; if TED heroically keeps, next in the cascade is the CPU, and that's the real reason why these machines easily got damaged.
Nonetheless, you can find tons of forum posts in the Plus/4 discussion groups, about this long running lie.
