This is a little off topic, but I was wondering if anyone knows of good sites that have info on building a simple computer from relays? I recently won 17...
I don't know of any sites with plans for a relay computer. There has been a lot of discussion here. You could search the archives for "relay." -Bob S. In a...
You can't do much with 17 relays. Zuse needed over a thousand (http://www.epemag.com/zuse/part4a.htm) Possible you can make simple games with them, like pong ...
... From: "sven" <sven2000@...> ... Radio Shack sold a toy computer which had 10 multi-pole switches and could solve many simple problems. It worked...
... could ... You might ... Yes, you're right, I'm sorry. I also remember the minivac, which had only 6. I'm not sure what it could do, but I agree it can...
Since we are discussing antiquated means of switching, does anyone have any experience with using vacuum tubes as switches, and does anyone know if these sorts...
You're getting into technology that's over half a century old. Constructing logic elements from vacuum tubes was already antiquated when I started learning...
... I believe that microwave-frequency components are still made with tubes --- such high-speed transistors are fairly new --- so you might be able to pick up...
Nearly a year ago Pasodad and I discussed how many clock and logic rods would be needed to generate any 8-to-8 state map. ... I have written such a program....
Hi all. Just a note to mention that I added links on the links page to two pictures on my website. One is a photo of my digicomp arranged in a strange group of...
Oh, yeah, that's the old Polaroid self developing pictures. The fat white strip at the bottom had a chemical capacitor which was charged by the camera's...
I love it! The perfect name for someone to answer that question! And exactly the answer I expected. I took a lot of pictures with my trusty Polaroid SX-70,...
Ouch! yeah, I kind of like the arrogant stupidity of a name like that too. considering how much knowledge is in the world for anyone to claim ownership of a...

Nope, not a Keystone... The Llama story was so good, I'd be willing to mock-up a Llama pic with the mountains of Peru and the tail of a jet fighter so you can...
In that case I have to guess it was a Kodak; either a "Kodak Instant" or a "Kodamatic". I still have my Polaroid Swinger which I got within months of them...
Hmmm.... in a pitiful attempt to recover lost prestige: It could be argued that because the court decided that the only difference between the polaroid and the...
Ok, yeah, let's end this thread and get back to the plastic processor... Yes Peter, "Kodak Instant" is right, but the "Instamatic" was actually a standard film...
Yes, the "Instamatic" was not instant but standard film. I was referring to the "Kodamatic" which was instant and not standard film (confused marketing group...

OK - I won't count the model 15 Teletype that was donated to my H.S. and a few of us dreamed of putting on-the-air as an Amateur Radio TTY device. (BTW - I...
