What a coincidence (re: me referring to it earlier today).
it also came with the RS232 Printer interface
and the following documentation:
4051 Graphic Systems Operation Manual
Plot 50 Introduction to Programming in Basic
4051 Graphic System Reference
Reference Guide to 4051 Basic
4050 Series Basic Reference Guide
amd 4051 Option 10 RS232 Printer Interface guide
Very nice!
What is really wierd is that I wrote some programs in
Basic for this machine
in 1977 using some of the built-in vector graphics routines, when I worked at
the Defense Mapping Agency, now called the National GeoSpatial Intelligence
Agency. I still have the tape cartridge (200K !!) when I loaded the tape...
presto... instant retro memories. I even wrote some notes to myself!! ( Note
to Homeland Security and to anyone else reading this email..It was NOT
classified!!)
If you're wanting/needing a "Plot 50" tape I have an extra. Let me know
(private reply, please).
