I recently bought an Amiga 1000 that also came with a C64 in the uncommon aftermarket case from South Australia. It cleaned up nice, apart from the UV yellowed keycaps. It's an NTSC board and I'm not sure if it's working. I tossed the 'brick of death' power supply that came with it and took it to my friends house so we could use his power supply and 1702 monitor. We got a black and white scrolling screen and stopped testing at that point. There's a good chance we had it hooked up incorrectly, so we'll be trying it again.
Are these cases considered 'rare' or are they just 'uncommon'?
Here it is all cleaned up, although no retrobright was done.
