Hi Everyone new to Forum and Vintage Apple Computing, picked up early revision pal UK Apple IIe, Poor thing is not working and generally sorry state thought it would be an interesting project. IIe has not ran in over 20 years so before i started though i would order new Capacitor PSU and spare set of Ram chips, capacitor no problem, ram chips have me a bit confused, never worked on vintage computer before so probaly a stupid question here goes. ram chips currently in machine all motorola mcm66665ap20 four marked five marked 8301 one marked 8303 and two marked 8241 why three different part numbers ? or are they date codes? i looked on ebay for replacement chips but could not find anything in the UK so looked for new ones. Are these any good ? Does anyone know of any suppliers in uk?
