A1000 hack?
« on: September 22, 2005, 09:00:22 AM »
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?

*THAT* is a pal colourburst crystal - I'm guessing the original owner had some sync problems that he created a finetuning circuit for?

Used those crystals alot in psx modifications heh
