Sinclair ZX80 / ZX81 / Z88 Forums

these will almost certainly be genuine, very good supplier.. http://www.ebay.co.uk/itm/MPS2369A-MOTO ... 0653829622 the type number 'print' is totally different, seems to be 'etched' ...

and i think that supplier above is where i got some mps2369s from..havent tried them yet..something about the type number printing doesnt look quite right, though..... maybe something else relabelled?!!

oh, what were these eeproms that were bad? and from what supplier? i've bought a fair few but not got round to using them yet...

are you thinking of offering an eprom burning service, or are you after someone to burn some for you?

oh, and 2N2369 plastic version... MPS2369 ...i have at least one zx81 that has these in...

sacré merde..£17.80.. i wish i'd bought a load at 50p each when i had the chance ...d'ohh!!

that fuller with the extension, and, yes, rampack is mine if you'd like the dimensions of the extender board, give me a few days to dig it out (part of my 'round to it' pile) and measure things

hmm, unliklely to be membrane as it sounds like its responding correctly but not 'printing' correct characters, 'could' certainly be duff ula (aarrgghh), but maybe strange rom or ram fault...

never mind dissolve the legend....it'll dissolve the keycap eventually

its usually when saving you dont want to have both leads connected? never known of a cassette recorder to take input on its mic socket when playing, but some certainly feed the mic input back out the ear socket when recording..??
