These areearly HP-12C manuals, and the dates make them more interesting than the many later HP-12C manuals on the market.
Your two books are:
HP-12C Owner's Handbook and Problem-Solving Guide— HP No.00012-90001, Rev. E, printed 9/83.
HP-12C Solutions Handbook— HP No.00012-90009, Rev. B, printed 1/82.
The second book is particularly early: the HP-12C itself was introduced in1981, and HP's June 1983 price list confirms that both these publications were contemporary accessories. At that time HP priced the Owner's Handbook at$10and the Solutions Handbook at$20.
These shouldn't be confused with the much more common later Owner's Handbook carrying the same 00012-90001 part number. HP continued revising it for years; for example, the HP Calculator Literature Archive has a January 1992 Edition 2 under the same part number, while collector documentation records Rev. F from May 1984.
