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.
Mine is a Basic machine and has serial number 15041. The serial number was
on a tag located on the bottom of the machine, and I didn't see any dates.
