Re-live the bygone years of RPN, 16 Kb total RAM, cassette tape storage, and plotted printing!

A friend is a vintage computer junkie and one of his recent purchases was a printer/plotter for his Sharp PC-1500A pocket computer.

Although the printer works, the pens, being almost 30 years old, do not nor are they still available.

This is an attempt to help him re-live the geeky years of his youth!
