Sweet, help desk didn't charge me to update the license, so was able to fix the pc for 40 bucks, might do the other three since they are pushing 10 years old to be on the safe side, or at least order a backup in case of emergency.
Caveat: Hospitality ain't my industry, and haven't touched those devices in well over a decade.
Based on the topology you described, may want to see if your vendor offers a thin client platform like wyse terminals (That's an example, not an endorsement).
Could be a middle ground between your aging gear now and the iPad platform that doesn't do what you need.
Nothing really lives on the terminal itself, which basically runs a shell back to a vm on your management server, and licensing for the terminals is also managed via your server side.
So if something goes wrong with the terminal hardware (intentionally cheap), just remove the license from it's s/n and assign it to a replacement terminal.
Back in the day I worked for a company that did hardware support for all kinds of things, and POS gear was part of it. Even back then chain restaurants were using a platform of that type for everything from the front end terminals, to the kitchen system, and even the back office.
I'd have to imagine that with the prevalence of open source devices like raspberry pi today, things have probably gotten more affordable compared to what I used to swap out.
