Re: Trends in keyboard design: Who started what?

I suppose that the number of symbol bits is not a limitation: A paper tape could record data in a serial pattern of single bits, and encode the symbols with Huffman coding. He published the paper in 1952. Huffman coding information theory is contemporary with paper tapes and cards. I went down a rab...

Re: Trends in keyboard design: Who started what?

Oh, hang on, it appears that my naïve assumption about binary character encoding on 80 column punch cards is probably very mistaken:

Re: Carpal tunnel syndrome... what worked for you?

Hi Mike, I agree that posture does help, and not only when typing. The activity that brings on the inflammation the worst is not keyboard typing, mind you. It's excessive DIY, working with hand tools. Gripping screwdrivers and turning hard is probably the biggest cause of pain. I've collected a larg...

It's a good video, thanks Redmaus. The thing is, I have very strong forearm muscles from martial arts and woodworking with traditional hand tools, including Japanese planes which need a very firm and controlled grip. Strength and flexibility of the wrists are good, but it appears that tendons passin...

Re: Trends in keyboard design: Who started what?

Curious. It is likely that the ancient IBM systems used EBCDIC, and not ASCII, and that was specified as having an eight bit character set.

Re: Trends in keyboard design: Who started what?

Unlikely that character-case was restricted: the 80 column punchcards seem to have at least eight bits per character. Some punchcards have twelve bits per column, with four bits presumably for error checking/correcting. Only paper tape with five-bit data characters would conceivably have such a rest...

Rather than spin another thread on carpal tunnel syndrome, I hope no one will mind me resurrecting this relatively mature one.

The IBM 5100 is in remarkably good condition. The CRT display is super crisp and inside seems surprisingly clean for its age. Hope it finds a worthy home.

It's getting to the point that a keyboard production run, with new components made from new injection moulding tools, based on vintage designs, is viable commercial proposition. The spiralling price trend is not abating, yet.
