Subject: Re: TI-99/4A acquisition
A number of early home computers liked to overheat.
More than two or three cards plugged-in the Apple II? Get a fan now, or
it's only a matter of time.. they even ran hot as-shipped.
My original VIC-20 ran frightfully hot, as did its power supply - just as
did the C-64 which replaced it. Both were run with a large muffin fan
positioned close behind the rear panel, which seemed to help a lot - both
machines have large slots in the rear, centred on the top plane of the
motherboard.
I'm not sure why this is, it's as if the manufacturers never actually
tested these machines under real-world operating conditions.
So true...
One of the first things I do w/ any Vic-20/C64 is remove that piece of
cardboard "RF shield". Kills what little airflow there may be. At some
point I should put some heat sinks on the chips that tend to run a bit hot
(VIC, PLA, etc).

That's about all I'm interested in, the 8 and 16 bit computers from late 70s
to mid 80s, so I'm all ears. :)
The TI99/4a is one of my favorites, nice score. Some great games on that
system. Parsec and Hunt the Wumpus are my favorites.
