VERY RARE HTF Litton Monroe 650 Nixie Tube Calculator Adding Machine 1970s Canon

Description: Incredibly rare top of the line Monroe model. Please make an offer. Monroe 650 CalculatorThe 650 is Monroe's version of Canon's Canola L163 desktop calculator, sharing the same basic internals, but packaged with Monroe's inimitable 'style' of machines from the era. The 650 is the top-end machine of Monroe's 600-Series, which include the 610, 620, 630, 640 and 650. The 650 works virtually identically to the Canon Canola L163, except for a couple of minor deviations. The 650 does not provide the [%] key (useful for percentage calculations) that is provided on the Canon L163. To make up for this, the Monroe 650 offers more capable memory functionality than the L163. All of this done in the interest of market differentiation, allowing Canon and Monroe to co-exist in the marketplace, yet sell machines that are essentially clones of each other internally. Monroe also marketed the Monroe 640, identical to the 650 with the only change being the omission of the square root function. Internally, the 640 and 650 are identical. The electronics of the 640 are fully capable of calculating square roots, but Monroe simply removed the [√] key to access the function on the 640. The additional cost for the square root key on the 650? $70! Just for a keyboard switch and key cap.
