@Humpleupagus @Tony ….
Completely unrelated but i was doing support for the purchase of a owner-manager machine shop a while ago and he took the time to show me his ERP system, that he had built inside of Lotus 1-2-3 v3.3 (the last DOS version). The most amusing thing was that he thought he had a complete system, even though 90% of it existed only inside his head.😑
