In case that's a serious question, many Chromebooks use ARM CPUs, both original and AArch64.

Re: Hmm, I've got a (not so?) crazy idea

My WFH desk takes inspiration from these integrated desks. The keyboard is held in place at the sides, so the total thickness is that of the keyboard alone.

Re: RS232 to USB?

On the PCB photo at https://terminals-wiki.org/wiki/index.p ... l_BCRU211G there are many traces running to the connector, so it's more likely parallel.

IBM 5252. When video displays were so expensive that two people had to share one. It had one CRT, facing down, and a pair of mirrors so that each user saw half the screen.

Re: Training Video for the IBM 029 Keypunch

One thing I noticed is the person has to hold the modifier down, including the Alpha modifier, which you have to hold down just to type standard alphas That's only true for typing alphas into a numeric field (and vice versa). Normally these machines were used for fixed-format data entry, and would ...

The serial number doesn't really tell us anything, a sticker on one of the microcontrollers has a handwritten date on it: 25.11.87 From a logistics point of view i can only imagine someone covering the ICs labeling during assembly, not before.

Re: How to figure out a keyboard protocol

Use the Pro Micro (or PC parallel port) to log the state of the data & clock lines when you press keys. If you get nothing, then probably the host needs to supply the clock, so try that (maybe start around 1kHz) and see if you get data.

They were preceded by typewriters. Some keyboards had solenoids to smack something, just to make up for the lack of smacking paper.

Re: Unshifted parentheses

Do you know whether this was an existing board with new keycaps or a from-scratch design? I don't know much about the Explorers. My understanding is that they were based on of the MIT LISP machine design, and that TI did not have any non-LISP workstations at the time. The keyboard of the IBM-PC com...

You can also make a nice puller out of a mini whisk — bend two loops to shape and remove the rest.

That's another area where the ordering of the characters tended to be quite bizarre (to me, at least).

Notice the ^~ key for instance. Seems to have the exact same legends.
That's just bit-paired ASCII. All it tells you is that the keyboard is later than 1967.

Yeah, the data pinout on the large part matches the 27xx EPROMs.

The other part is also on the data bus and only has 4 unaccounted pins. I don't recognize it as a common shift register.
