FUN FACT: for at least the first couple iterations of the A2, the computer would “seize-up,” and then you’d have to lift the top off, likely shut it down (but not everyone did!), then push down gently on each IC (chip), attempting to ascertain which one might be doing “pokies.” (i.e. lifting out of its socket)
I don’t think it was a heat issue (but I might be wrong), but rather that the first couple runs of IC sockets didn’t exactly match up with the actual chips!
TBH, I’ve never really researched this stuff, so I might be wildly incorrect about the actual cause. But just like the Nintendo NES folks who blew their saliva-breath on poorly-functioning cartridge leads, it doggone WORKED. 😀
Because of the way it is, it is indistinguishable from a regular sized one
Cool.
I just noticed this is OC. Is this yours, OP? From a museum? What’s its story?
Yes. Computer museum. Unfortunately taking photos was difficult because many of the displays had reflective glass coverings and lighting setups causing lots of glare.
Here however is an actual Apple 1 board:
That’s a lot of (I guess) memory chips!
Lots of binary decoders, multiplexers and counters so it’s probably something to do with the ALU (arithmetic logic unit, where the computer does all its maths)
