82162a HP-IL thermal printer success

[hth]

I could never afford a printer back then and only used one briefly when a friend temporarily had a borrowed 82143A, but my feeling was that everyone that could afford to expand their HP41 system went for HP-IL.

You have to remember that in the early days, ports was quickly filled up and people looked for ways to plug in more peripherals, if they could afford.

Memory modules very combined in single shells, modules were wired inside. Port extenders were used. HP introduced first the CV to free up ports from memory modules, then CX to free more ports from Extended functions and Time module.

The 82162A printer was a way to reduce another port and it probably made more sense when using HP-IL.
