as in title,looking for two amstrad 40058 asic's for a spectrum 128+2.ic10.
or equivalent.
dont know if these fail alot or not as ive just had a spectrum break down for absolutely no reason while fixing the tape deck
anybody know what parts fail in these machines?
ive got two with exactly the same symptoms but one was working just a while ago...
EDIT:hmm,apparently these are PCF1306P and ZX8401...i have seen the ZX8401's on 48k spectrums on a issue 6 can anyone please confirm these are the same parts?
and if they are they are multiplexers?
or is there a way to make these up on a pcb with 74 logic to replace them and plug them into a socket?
