I obtained an A1000 yesterday. It works great!
The machine has a memory expansion at the front trapdoor. It is on
this picture. This hardware has not a single brand or designation on it. Total memory is about 1MB (half chip, half fast).
I was curious what would be inside so I opened it up. Wow, is that complicated! I also saw some rework (
lot of wires) which I suppose has to do with the RAM. But there was also
this modification. What the heck is that for?
