I'm thinking I don't have all my facts straight with this question, but: A really successful bookstore in my town has been using a networked DOS POS system since as long as they've had POS software. I asked about it once, liking the look of the old monitors and antiquated user interface, and I thought they called it Wordstar. They gave me some more details like how there is still one support company that will actually help them from time to time when they need something looked into. Mostly saying that they've never moved on because it does (almost) exactly what they need. But now I'm thinking I either a) misheard them, or b) I'm just confusing myself right now because the wording was similar. Has Wordstar been used in addition to word processing for custom solutions/software? edit: giving it some more thought, I'm now wondering if they were using Wordstar or otherwise for inventory purposes only, and using ANOTHER piece of software for the actual sales. edit: looks like I am very possibly thinking of http://www.wordstock.com/o_view.html http://www.wordstock.com/o_view.html
