Auction is for a lightly used vintage HP 7475A Plotter with several packages of pens as shown. Some of the packages are open, and contain at least two pens. I tested this by performing the power on demo which you can see. The pen's are well over 20 years old which is why it is so faint. The paper tracked true through the rollers and the plotting mechanism swapped pens back and forth precisely. I used to use this about 25 years ago to produce an occasional ...custom map for a document. I will include a power cord. You will need to get the correct RS232 cable for your computer to drive it. You can find USB to RS232 adaptors on the internet and then get a gender matched 25 pin cable to make it work. I do not recall whether you need a cross over or not. I will include the cable diagram document as shown. Somewhere around here I have the programming manual and if I find it I will list that separately. It has the codes and protocols to send the plotter through a C program or other language. This worked great when it was packed up. It powers on and performs a demo as it should. Paypal only please. Sold as-is.
