My serial number project is going slowly. I only
received two responses (thanks, Charlie and Joe) and so my sample set has a woeful three
date points:13352 (Charlie's), 13513 (mine, sold 1/77) and 14213 (Joe's, sold
9/77). Perhaps a rate of about 1000 units per year in 1977, but too little info to tell.
If this rate is correct, I would suspect the the numbering began around 12000 or so.
C'mon everybody, have a look at the back of your 5100 (the number is engraved into the
back of the case, usually preceeded by a "10-") and keep those numbers coming.
Actually mine is on a metal plate on the bottom of the machine.
