Hot take? Every editable text field should be an Emacs buffer. I don't want your semi-arsed Emacs keybindings, I want the full thing.

  1. I remember CRTs,
  2. I survived contact with CRTs.

@kbob It's not a standard PDP-10 thing for sure. The display is the "color scope" by DEC. The story goes (not confirmed) that two were made as an experiment, and one was given to MIT's AI lab (apparently a popular dumping ground for DEC hardware). This would have been around 1970, give or take a few years. You can think of it as a point-plotting device, similar to the Type 30 used with the PDP-1, except lower resolution and four bits each for RGB. The tube was supposedly a regular NTSC.

@kbob @zxdunny I agree with your assessment of the history. I first saw Mr Dunn's post, and then harassed... gently inquired about its origin until he could dredge up the Twitter post. I'll admit I'm quite pleased the history now includes a PDP-10 twist.

Somehow, writing Forth in 64x16 screens was one of the most enjoyable jobs I had in my entire career. It might seem like the severe constraints of the language and the 1024 byte block size would be limiting, but it felt the opposite.

@philcowans Just curious, why are you interested in CTSS archives? Are they prevalent in use? Many specimens on backup tapes? No one decoded the format yet? I'm interested because in some ways CTSS was a predecessor to ITS, and ITS has archive files too. I made a tool to extract files them, but some archives on backup tapes defy decoding. Even by ITS itself.
