8-bit acorn hardware • Re: Who else is building a Beeb from scratch?

Well, I've finally put together one board out of three and I've got serious stability problems and the Econet just returns "Line jammed" I'm wondering if my stash of "new" 6502A ICs is fake. I bought them off eBay a long time ago and tested them on the 3-Chip Plus - but it dawned on me that they are probably 1MHz parts and that's why they are reported by the chip tester and 3-Chip Plus as good, but crap out after a while on the Beeb making it like an electronic box o' frogs...
It looks reasonable, I haven't tried solvent on it apart from the freezer spray - the IC runs hot.
