I bought this for $5 at the local Goodwill computer store. (They also have a museum in back with an autographed Dell, a Cray, a PDP-8, a Data General Eclipse, an Imsai, a Lisa, a Datapoint terminal, ... but I digress... ) It is a USB device. "Play" is as in toy, not as in Playstation. It does work well enough for what it is. The biggest problem for me is that the illumination is too bright for coins and the controls for brightness do not do much for that. It is 10x, 60x, 200x. Ten power is fine for coins. Most coins are too large. The best field of view was with a couple of hemi-obols, coins that weigh about one-third of a gram, about 5 mm in diameter. The interface is cute. Every control plays a funny sound. The software includes "paint" type commands for editing. You can build an album of nine images and run them as a slide show. Le Petite Prince from the France 50-franc note of 1993 at 10X. HP to right (stern) of ship on UK half pence of 1964 at 60X.
Abdera c. 510 BCE. Uncatalogued. silver half-obol. 0.33 grams; diameter 5 mm ~ one-eighth inch. at 10 X.
