Hi,
So I've got my hands on this 464, check the pictures. It was so mucky when I got it, I've since taken it apart and given it a good clean and I can now touch it without feeling sick! =) The red light comes on, but I get no output / black screen (I'm using a scart kit from retroshack). Pressing delete does not yield a sound. The tape deck happily rewinds and fast forwards. I have a multimeter, soldering iron and a lot of patience, I've ordered 10 RAM IC that were recommended elsewhere on this forum.
Now, the 464 came with a non standard power supply that was being used with it, it says 6v on it, but when I tested it, it was kicking out 10v - will this have killed my board?
Should I just put this 464 aside and use it for spares, can it be saved? I've learnt so much already, I'm willing to spend a bit of money on new IC and sockets etc and could have access to a decent oscilloscope when I get back to work*.
Thanks guys, I've spend some time on here already and posted a couple of times, this is a great community. My goal is to actually play a few games and have a go typing up some games from basic code in magazines etc and just generally relive a fun part of my youth.
You didn't mention before that it was in THAT state! The RAMs are probably fine, but it has a serious rust problem. It'd consider it fully saveable, but it's a lot of work. If you don't want to go to the bother, send it over and I'll bring it back to life.
I have a soft spot for rusty things... http://www.cpcwiki.eu/forum/amstrad-cpc-hardware/hardcore-floppy-drive-restoration/

So the 10v adapter that was used to test it wont have killed it? I might have to send it to you if I want to play Xanagrams before Christmas!
Even 6V isn't good for a CPC. The PSU probably doesn't output 10V though, you most likely measured the voltage without a load attached. Send it over if you like.

My CPC got killed with 12V. Everthing survived, but RAM was blown completely. Every chip.
