Twin Red Arrow

The Twin Red Arrow, made by J. H. Keeney and Company Incorporated and announced in September 1960, is a two-player "electronic upright," or "flasher type" device rather than a pinball machine. As with other machines in this family, a credit meter increments instead of paying out cash.

Its most distinctive feature is the Panascope display — one of three projection units used in the game — an "In-Line Readout" device invented in 1956 by Industrial Electronic Engineers of North Hollywood as a competitor to the Nixie tube. Keeney's vice president of sales, Paul Huebsch, publicly credited the company's engineers with months of work perfecting the scoring ratios needed to make the projection system profitable for operators. The cabinet, with tapered legs, was advertised at 59 inches high, 30 inches wide, and 18 inches deep, weighing 155 pounds.

While Keeney did not invent the underlying projection technology, the Twin Red Arrow's use of it reflects the era's push to compete with newer scoring displays, making it a notable example of Keeney's engineering effort in the early 1960s.
