Anatomy of an 8-Bit Over-Voltage

[endangermice]

Hehe this reminds me of those playground arguments I had back in the day (I was a CPC owner). I think overall the Amstrad was the better machine, well for me as a programmer it was - better keyboard, better Basic, fast reliable disc drive nice ROM expansion system and could do colours that weren't just variations of brown and had no colour clash!


Having said that I was always very jealous of that fantastic SID chip on the C64 and of course the fully featured hardware scrolling not to mention hardware sprites! Having said that the CPC had more than a few games that allowed it to truly shine - Ghostbusters 2, Head over Heels, Arkanoid,Barbarian to name but a few!


I pulled the C64 out over the weekend and so far I can confirm that the SID chip is indeed not only dead but shorting out, the VIC II on the other hand has miraculously survived! I powered up the board only to discover that the 6510 is missing and I really cannot remember what I did with it - doh!

Its power was its downfall....

after many discussions with Blurredman regarding his unfortunate over-voltage incidents with several CPC's, it got me wondering exactly how much damage and what gets damaged when this happens.

Thats's easy.

Situation: a litte boy tried use the cpc outsite ctm 644,uses a "universal ac/dc adpatador with the cpc".Uses 3,5v,5v,5v,7,5v,9v,12v selectable 100% china adapter.

Result:Brommmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm!!!

CPC RIp.(a beautiful casacade of colours in the screen is the result).

Go repair service.

You don't have small screens ? 

Today, the best was to use the "+5V (2/3A) / +12V (1.5/2A)" small power supply found with external 3"1/2 HDD cases.
Can input 110/240V, so it's clean and you may use your CPC everywere too.

See the nice tutorial on Amstrad Today.
