That reminds me of something I’d love to learn a bit more about: the Strong Museum of Play. It appears the Wegmans’ supermarket exhibit where kids are able to work with real point-of-sale equipment has actually gotten equipment refreshes over the years itself, and I was really amused to see how far they went to have a “fully working” setup in the exhibits for kids to play with.

The checkout counters are actual IBM/Toshiba SurePOS lanes, with actual current Datalogic scanner scales, and they’ve got a OS4690/TCxSky install and SurePOS ACE running on every single lane. (Or, at least, one of those registers has to be a controller+terminal, the other 5 lanes have to bootstrap off at least one lane, so they’re all networked, too!) They’ve also maintained enough of the store configuration so receipts look just like a store receipt and all (of course, with the Strong Museum as the “store”). And yes, you’re told to only push certain buttons and only scan stuff that’s inside the environment… ;)
Over the years they’ve swapped out the lanes from the old white to the modern Slate Grey, upgraded the scanner-scales, but the UX is still the same as it always was.
