The Busicom 1210PD is a decent sized desktop mains powered calculator with a built in printer. This calculator, like the mighty Silver-Reed 1250PD, is intended for heavy duty number work such as working out the wages for the workers on a Friday.
The calculator works well, though required a new ribbon (this has now been fitted). Despite it's age it seems to work electronically pretty well with few if any glitches. Numbers are shown in a nice cyan blue VFD display.
