Hardware Description

The 9805A was a low-cost computer/calculator designed for statistics calculations. It had a much smaller form factor than the 98X0 computers and did not share common parts. Expanded functionality was achieved by plugging in a ROM block which included specialist keys onto the key panel. It came standard with a built-in full-character impact printer. The 9805A could also be connected to a 9862A plotter.
