The HP-97

Display: LED, 10digits (+2 in sci. not.)

Power: 4 rechargable Sub-C cells (in proprietary packaging), AC adaptor

Adv. Functions: Trig, logs, stats

Memories: 26

Programming: Steps 224 (merged), goto, conditional branching, subroutines, flags, and labels. Reads/writes programs, memories, and state to magnetic cards

Comments: Made from 1976 to 1982, they retailed for about $750.

Comments: This calculator is the desktop twin to the HP-67 - programs (on magnetic cards) are interchangable between the two. The only functional difference is the 97's printer. I love having this on my desk!
