Vintage Hewlett Packard HP-12C Owner's Handbook and Problem-Solving Guide (1984)

This is a copy of the HP-12C owner's handbook and problem-solving guide, from 1984, in paperback, in excellent condition for its age. It's unmarked apart from the title page where the previous owner wrote their name, and the spine is un-creased (as if never opened, which I suspect might be the case). 246 pages of financial programmable loveliness.
