If you tried to execute name of the ROM, that might be why it is saying "nonexistant". Try entering 100 and then XEQ C>F, see if you don't get 212. Otherwise "nonexistant" probably means it needs another pack to be present. You could try to load the programs into main memory and then examine them in Program mode, look for statements labeled "XROM xxyy", you can figure out from these what ROM they are trying to use.
The quartz window Tony is talking about might be under the paper label.
Some of those functions sound like temperature conversion, and then you have "ft>m", feet to meters. Maybe something to do with refrigeration?

Sounds to me like it deals with aviation. Some of the apreviations are familiar to me. Like FLT means Flight, HAT might be Hight above Threshold, f<c Fahrenheit to Celsius conversion, TS True Speed and so on. I think that Ellis is on the right way. The modul it self I unfortunaltely don't know but as I have seen Tony is on the Re:-List that's a good start! He helpt me as well a year ago with very good advices. Greetings from Switzerland Stephan.
