Welcoming a new (old) printer (back) into my fleet: a LaserWriter II. It’s a workhorse of a printer from 1988 dressed in Snow White design language. #RetroComputing ImageImageImage I had one just like it for years that I used almost daily but jettisoned it some time ago. This one comes to me thanks to @compu_85! You can see here where he was repairing a series of these a few weeks ago.

Did you know there were typewriters that used ball point pens to draw not just text but also graphics? I’ve collected several of these over the years. Thread: 🧵 #plottertwitter #RetroComputing

Image Panasonic made three models. The top shelf was the RK-P400C Penwriter which included the RS-232 port built in for computer control. They also came with a white pen for error correcting.

Today’s #genuary2021 prompt is Rule 30. Glad to have the time today to participate so here’s a couple of new #plottertwitter variations I created. Random initial states. I used the HP 7550+ for the one Rule 30 plot. I’m still astonished that it’s this fast. #plottertwitter

The newest plotter in my collection is also a.. calculator? The Sharpgraph EL-7050 plotting calculator could produce circle, line, band, and bar charts on 2.25” paper using the micro Alps mechanism. Anyone have a service manual? #plottertwitter Lurking inside is a NiCD 4xAA battery pack that’s typical from 1983. It’s leaking so out it goes. You can also see the Alps DPG-1301 micro plotter mechanism and the power section.
