Wow, what a memory rush. I used to color on fanfold line printer paper like this. When I was in kindergarten I'd sometimes go with my dad to work on a weekend when he needed to debug a job. I think those are the exact printer and keypunch models.
I would happily play on the punchcard machines for ages. When you turned one on (with the flip of a heavy switch) they'd start humming, giving a sense of coiled power. I loved the crisp thud of each punch, and the fluffy mass of little squares in the bin that collected waste. Compared with modern computing technology, they have a very industrial feel. I remember being delighted that my last name was all on the top row of the keyboard.
I also remember being absolutely fascinated by insert mode on the terminals. I could make shapes with the symbols and then make them move forward by arrowing back and holding down the spacebar. The slowly fading green glow of the phosphors was magical to me, as was the way each letter was composed of visible dots.
There was a haecceity, a thisness to early tech like this that I miss a little in comparison with the incredibly flexible devices of today. I wouldn't go back, of course, but I definitely get why people spent time maintaining and restoring relics like this.

If you have nostalgia for phosphor, but don't want a huge, hot, CRT in your office, and you have Mac, check out the terminal emulator "Cathode": http://www.secretgeometry.com/apps/cathode/
(No association. I just like the product.) It's extremely configurable, you can simulate a wide variety of tubes in various states of (dis)repair.
Probably the perfect way to play nethack.
