This hard-copy terminal features an internal modem, thermal printer, Alps SKFL switches, and doubleshot ABS keycaps.
The yellowing was resolved with a cleaning and sous-vide-retrobright. The rest of the unit got a good cleaning but was otherwise in good shape. A couple of the switches require a firm press to register and could probably use a cleaning however I'm not sure there's any way to non-destructively open the switches.
Actually getting the terminal working was a bit of fun. It requires a phone line, no RS232. That entails phone line simulators and a USB modem. Surprisingly it was nearly plug and play with a modern Linux machine. Getty picks up the modem when an outbound call is initiated and bash works as expected.
