HP 12C manual

[rprosperi]

I have no specific and I suspect that it's really hard to answer all these questions as the 12C has been in continuous production since 1980, produced in 6 more countries, with many different manual printings, bindings and formats.

Any booklet containing '71 accessories cannot be before late 1983 so this is certainly not from original 12C production if that's all you're asking.

Also, most brochures have a date printed on the bottom back page; the date of the brochure is almost certainly very close to the manual's date, they did not print huge qtys of manuals to set around in warehouses waiting for the next production run, they were continuously printed and packaged.
