Pre-Raster Graphics

David Gesswein is considered to be one of the reigning experts in DEC’s PDP-8. Almost every time I’ve been to a VCF East, David is there with a PDP-8 of some kind, usually an 8/e, and this time was no exception. He took portraits with a modern camera, then converted them to ASCII and printed them out on a large, beautiful, dot-matrix printer – I plan on framing mine!

There was also a Tektronix 4014 showing just how much resolution the 1970s had to offer (if only in monochrome). Brian Stuart, who had the exhibit on Forth, borrowed this terminal to test one of his programs on the authentic piece of kit and it was beautiful. If I understand correctly, unlike other terminals of the era, Tektronix graphical terminals had on-board storage to keep images locally. You’ll note the bank of circuit boards that sat in the cabinet under the CRT to facilitate storage and precision graphical rendering.

Lastly, David had a really cool Calcomp 563 plotter drawing really cool artwork, one line at a time. Makes me want a plotter…

“Multiple graphics technologies will be exhibited that were common before raster graphics won. See 4K graphics on a 1970s Tektronix 4014 vector storage terminal. Have your picture taken by a PDP-8 computer and printed on a 200 line-per-minute chain printer in glorious ASCII art. See a pen plotter operate.”

a lot of terminals of the 70s and into the 80s kept substantial amounts of memory onboard, so as to reduce the amount of data that needed to be sent back and forth between terminal and host constantly - thus allowing the host system to handle more simultaneous users and allowing the remote terminal to operate effectively on lower bandwidth/cheaper/lower quality links

many of these terminals would be just short of capable of operating meaningful programs wholly local, if they’d only had local permanent storage

Most serial dumb terminals stored the screen contents of anywhere from 40 to 80 characters per line, and 20+ lines worth of text. All told, that isn’t all that much information to store in RAM to keep rewriting to the screen.

The Tektronix 4014 is in a whole other league, and works a bit differently (based on my cursory understanding of the technology it employs). Rather than keeping that information in RAM, it’s using the picture tube to store the graphical information for vector mode – phosphor dot by phosphor dot.

As a result, it can store an image that would otherwise take up about 1MB, assuming you were storing it in raster. 1MB in the 1970s would have been a massive amount of secondary storage, certainly nothing would have had that much RAM. Not to mention, storing any useful numbers of coordinates for curves to render would have taken significantly more computing power than any terminal should have had during an era when minicomputers reigned supreme.

**ascii-drawings to pish-machine** — 27-year-old British artist Keira Rathbone does not use a brush or pencil. Their it successfully replaces the typewriter. Kira first began experimenting with a typewriter, even at the university. 30 typewriters that she used to create unique portraits. Such as: Obama, Kate Moss, Marilyn Monroe.
