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.
Thanks.
