HP 7475A

The Hewlett-Packard 7475A is a 6-pen plotter from 1983. It can draw on either A3- or A4-sized paper and speaks HP-GL over an RS232 serial port. These things are really cool to watch while in action and are practically indestructible.

I wrote a tiny Python script, hpglplot, to plot HP-GL files on this plotter using software handshaking (so you can use a simple three-wire serial cable without any problems).
