more unsorted vintage computer & electronic stuff

electronic and electrical parts
Growing up in the 60s, I grew up with images of NASA mission control and huge mainframe computer consoles (real and in movies),
so I adore brightly colored illuminated switches and indicators,
particularly military surplus (very rugged, dual lamps, built in self-test and front-replaceable).
A handheld pushbutton THAT LIGHTS UP (so you know when it's ready and armed!)
A lovely assortment of indicators, still waiting for projects worthy to use them.
I was hoping this Belkin Nostromo Speedpad would be adaptable for alternate input methods
similar to a twiddler chording keyboard but I never got that far.
It's already surpassed by a cordless version.
Here's a curiousity I found at a thrift shop: the Datadesk Littlefingers LF2000 keyboard.
A small keyboard for children to learn "keyboarding skills" (it's no longer called "typing class").
The build-in trackball caught my attention because I prefer them to mice or touchpads.
VINTAGE electronic and electrical parts
Until recently, ALL computer printers used tractor feed for continuous forms (particularly large high-speed line printers). Here's something rarely seen: fanfold index cards! I was a computer/terminal operator in high school and we used the computer to print postcards for things like warning parents when students were absent for too long.
Fanfold computer punched cards! You had to separate them for keypunching but this allowed printing all over them (for whatever reason).
Back in the day, checks and bills were printed on punched cards to return with the payment, but they were pre-printed with anti-forgery stuff and somehow pre-punched with the check or account number.
No, not a spool of computer tape but audio recording tape! It's HUGE and over an inch wide! And came in its own plastic carrying case!
Now known as American Science & Surplus, the Jerryco surplus catalogue was chock full of weird and wonderful stuff.
It's still written with wonderfully silly descriptions.
