In this Ferengi Friday video we take a look at some special purpose vintage pocket computers. One came with a kit of metrological equipment for helping racers set up their carts, another came with two special purpose HVAC calculation ROM modules. We also have a hard-to-find Sharp EL-5500-T and an accessory for a vintage laptop that weighs 5x what the laptop does. Will the Nagus be pleased?
