Re: Help to identify this keyboard

Most likely a terminal. A word processor or typewriter wouldn't have a bit-paired ASCII layout.

side question, any idea what the "Do" button does?
It's effectively F16 (look at the F numbering of the whole row) and sends ESC [ 2 9 ~ (which is what pretty much every modern terminal will send for F16, if you have that many). I gather some VMS software used it to trigger or confirm actions.

Re: Tektronix 4120

Turning on a fourteenth LED by sending the highest possible code (31) actually drives a 555 timer connected to the speaker to play a tone. Even though that's a lot of hardware for this, there does not appear to be any way to change the note. And this keyboard seems to be too late for the craze of b...

Re: How do I figure out a Keyboards Scan Codes?

To be frank, unless you also want to get in to vintage test equipment, you'll probably be better with one of the cheap USB interfaces (example). For one thing, once you figure out the format, you can just export the scan code data rather than reading traces off a screen.

Re: How do I figure out a Keyboards Scan Codes?

What you want is not an oscilloscope but a logic analyzer. For some keyboards, yes, you will have to press every key and record the result. For others, you'll quickly discover a pattern.

Re: Hex numpads?

Many hardware tools (e.g. logic analyzers) and single-board computers had hex keypads, but that's not really the same as a hex keypad on a regular text keyboard (or using the same interface as a regular text keyboard).

Re: Hex numpads?

It looks like that group of codes were oriented to a hex-calculator style keypad. Unfortunately USB hasn't published any rationale for their choices. If they were used, it wasn't on anything in the ‘mainstream’ PC lineage — Windows and Linux both ignore them.

Re: Question about keyboard layouts and scancodes

Since you mentioned ‘2B’, I assume that by ‘scancodes’ you mean Windows codes. Those are based on IBM Set 1 scan codes from the IBM PC , which only had one format so it didn't need a way to distinguish them. Even if you have a keyboard that does distinguish them (e.g. USB or PS/2 Set 3 scan codes), ...
