Ha ha
He also did the TV typewriter:
https://en.wikipedia.org/wiki/TV_Typewriter https://en.wikipedia.org/wiki/TV_Typewriter
which allowed people to have something to hook their bare board micro to.
I had money to buy his green book, but not the computer or the TV. :)
- sehugg 6y agoWhich used the same technique as the Apple 1 video terminal, though Woz claims not to have known about it when designing it. Probably true, because there weren't many inexpensive options for RAM besides shift registers! https://www.willegal.net/appleii/apple1.htm https://www.willegal.net/appleii/apple1.htm
- djmips 6y agoI wouldn't be surprised if he hadn't come across it and perhaps forgotten about it. Nevertheless simultaneous invention happens all the time.
- koalahedron 6y ago> Nevertheless simultaneous invention happens all the time. Try telling that to Isaac Newton. :) Or better yet Edison or the USPTO.
- djmips 6y agoAnd this technique was also used for video output on the Sinclair ZX-80 if I am not mistaken.
- jecel 6y agoHe later had books mentioned in other comments: "The Cheap Video Cookbook" and "Son of Cheap Video". In these he added just a few TTLs to a Kim-1 computer and generated video using mostly software. The Sinclair ZX-80 was much closer to this than to the TV Typewriter (which was 100% hardware). Some other computers that used this technique back in the day: https://en.wikipedia.org/wiki/Aamber_Pegasus https://en.wikipedia.org/wiki/Aamber_Pegasus https://en.wikipedia.org/wiki/Galaksija_(computer) https://en.wikipedia.org/wiki/Galaksija_(computer) And here is a recent project: https://en.wikipedia.org/wiki/Gigatron_TTL https://en.wikipedia.org/wiki/Gigatron_TTL
- vram22 6y agoActually, some microcomputers (apart from bare board micros) had the option to use a TV as a monitor in the early days.
- kwhitefoot 6y agoSome? In my experience it was almost all. At least that's how it was in the UK.
- uxp100 6y agoThe article is from 1973. I think exact eras are getting a little muddled here. Altair, Mark-8, SCELBI, these are the sort of home computer that came out shortly AFTER this project was published.

- kwhitefoot 6y agoAh, serves me right for jumping straight to the comments. I had in mind computers from a few years later like my Nascom 2 from 1979.
- uxp100 6y agoIt really all happened quite quickly.
- vram22 6y agoYou are probably right. I first wrote "many", then edited it to say "some", in the interest of accuracy, since I had only used a few kinds myself, and did not know if all the others supported that feature or not :)
- vram22 6y agoDid all that, before your reply, BTW.
