I buy and sell old consoles and games and whenever I have a cart that refuses to work I use MAPLIN (www.maplin.co.uk)
( N61AN ) Contact Clean 200ml £2.50 ( N64AN ) PCB Cleaner 200ml . £3 This de-oxidises and generally helps with dry joints etc. More often than not this is enough. The good thing about MAPLIN is that they tend to deliver very quickly, often next working day ! >>> [EMAIL PROTECTED] 18 September 2006 11:16 >>> Tony Firshman wrote: > Ade Vickers wrote: > > > > Possibly - but would a connector give up when the chip had been > > undisturbed for ~10 years? > Indeed it could.

I think so - I will dig the old girl out of her box this afternoon and check. > If it is the original membrane be *very* careful. Tails will > break easily. I bet when (if) it starts up, some keys will not work! Not original - I've used 3 membranes over the last 20 years - I now have one of the new RWAP ones, so I'm hoping for years of trouble-free service from the keyboard from now on.
