Hi all, just joined this forum. Have commenced my Mac collecting career with buying (at an extortionate price!) what I hope is an original 1984 128k. However, I did want to cross check the authenticity as it came through ebay and we all know what skullduggery can go on there. It is badged just "Macintosh" on the back but is there a resource somewhere that will enable me to cross check the serial number to ensure I have an original (i.e. to get an approx date of manufacture) and nothing re-badged? (The serial number is F4341QPM0001 - in case anyone can help me directly). Or are there any other ways of confirming this is an early 128k rather than a 256k or a later 128k - either inside or outside the case? All help and comments gratefully received. Have great days.
