Cellatron R44 SM - A Demonstration

I received this new calculator yesterday and have spent most of yesterday and today translating the manual into English (was German). I have some strange ways of unwinding, but it's been legitimately relaxing. Please let me know in the comments if you have any questions about the machine or similar. I'll be happy to answer them. Sorry about being a little bit spaced out as well. I had an accident with some cleaner fluid earlier in the day. You'd think outdoors would fit the "make sure you are in a well-ventilated area" criteria, but you would be wrong. However I digress.
