[GreenKeys] Flexo & TTY pix

[Jones, Douglas W]

Rutherford Labs in Englad has a huge photo archive on line.

Among the goodies here are lots of photos of racks full of electronics (mostly from physics experiments and physics experiment data analysis, but that includes computers, leading to:

- first slide of set:
An ICT code chart for the 5-level and 7-level codes used on the Orion and Atlas computers.  The 7 level codes are definitely not ASCII -- If you number the bits 7654o321 (o is the sprocket), then bit 5 is parity.

- 10th slide of set:
Rear view of a Flexowriter on the classy Friden table (I want one!) that had provisions on the left table leg to mount the feed reel for the punch and a large bin to catch chad and paper tape.  This is, I believe, the same table as is shown from the front on page 2 of this Friden brochure:

- 11th slide of set:
Back view of an TTY Model ASR 35
- 15th slide of set:
Front fiew of TTY Model ASR 35

- 5th to 7th slides of set:
DEC PDP-15 system with back view of KSR 35

- 9th and 11th slide of set
PDP-15 with TTY Model KSR 35 and KSR 33 and DEC graphics display with light pen and digitizer pad.

There's more, but I don't have time to explore it all.  Now that I've found both front and rear views of the Flexowriter table that goes with my Flexowriter, it will be possible to work up reasonably accurate drawings of the table.
