Later plotters used standard interfaces such as serial and high level command sets which let you send the end points for lines and text for the plotter to draw. They could also draw much faster, over 30 inches per second on high end plotters. The pen plotters have pretty much been replaced by plotters which are large inkjet printers. Modern plotters use either sheets of paper or roll paper without sprocket feed holes.

I recently purchased the pressurized ink cartridges and liquid ink nibs from eBay seller plothropa2z. If his current auctions doesn't list any he may still have some available. You should be able to contact him through eBay. He doesn't have all but this lists what pressurized ink cartridges were available. These someone sent me the links. I have not purchased from them. Pen cross reference table and pen sales and another pen source with price.
Jeffrey S. Jonas 1627 page has pictures of the accessories and links to sites with more information on this plotter. My plotter is missing the accessories and the roll paper is no longer made. If anybody has these items I would be interested. Contact info at end of this page. I have recently gotten enough new old stock roll paper to last me for a while. I'm also working on making reproductions of the missing accessories. Pictures of the progress below.
This site has pictures of some of the accessories for the plotter that I don't have.
