Antique Calculator Collection


These calculators are all either engineering marvels, or at least have Nixie Tubes :-)


The HP-9100B


Front View of HP-9100 S M L XL This HP-9100B was donated to me by a buddy who got it at a garage sale for $10; this would have been around the mid-1990 timeframe. It is seems to operate properly, but I don't have any magnetic cards for it.


The Tektronix 909


Front View of Tektronix 909 S M L XL This Tektronix 909 calculator was donated to me by the same guy who donated the HP-9100B. He found this one at the Stittsville Flea Market, and paid about $5 for it. This machine is functioning, but some of the Nixies flicker, and a few don't light up at all.


The Monroe 630


Monroe 630 S M L XL This Monroe 630 calculator was donated around April 2003 from California, by a buddy who saved it from the scrap heap at his local high school where he is a teacher. This machine is not functioning -- it displays a "0" but doesn't react to any of the keys. Unfortunately it's a "one chip wonder" so I doubt I'll be able to fix it :-(
