Well I was just seriously outbid on an eBay Digi-comp 1. The thing sold for $400 and I only went up to $250 8-(. My father bought a Digi- comp 1 when I was...

One possible approach to speeding up the process of bringout out a new version of the Digi-comps is to follow the Open Source development model. Create a group...
I agree. In this case "open source" would be 1) a set of CNC milling machine toolpaths so anyone can make a Digi-Comp I using a Roland engraving machine, plus...
I'm just reading the book "The Tinkertoy Computer", http://www.rci.rutgers.edu/~cfs/472_html/Intro/TinkertoyComputer/TinkerToy.html or http://tinyurl.com/338ap...
Right, this is the famous tinkertoy tic-tac-toe computer that Danny Hillis, inventor of the Connection Machine, and once CTO of Thinking Machines Corp., along...
To answer your second question, yes, someone posted a "circuit diagram" for the Digi-Comp I using standard logic symbols to this very list. It must have been...
From the book's description, the Tinkertoy Computer (version-2) is basically a lookup table. Although Digi-Comp 1 is smaller, I believe it is more complex....
Is anyone else getting these security messages? I've had three since last week. I've replied to them asking for details, but nothing has come of that. I...
It probably isn't you. A lot of viruses steal mail addresses and forge emails that appear to come from legitimate senders. NM ... From: <pasodad@...> Is...
It's not "spoofing" because I got another alert when I sent that last message. If it's something in the content, it may be hyperlinks, HTML text, or something...

Hi, I am an original digi-comp 1 owner (as a child), have retrieved it from my parent's house, and had assembled it again recently. However, the rubber bands...
I cut large (but thin) rubber bands and tied a knots in them to make the right size. You get total control over the spring force this way. Bob S. ... ...
Some models (the earlier?) used rubber bands, others used a spring. The model I have uses springs. If (and I say IF, because I don't know for sure) the...
In the old days, we used to use these tiny rubber bands that some kids used on their braces. They were the perfect size. Maybe an orthodontist can supply some....
I think I'm going to try this out -- thanks. Does anyone know if the digicomp box type is related to the rubber band vs springs?? I have the large, almost...
Hi, it's good to be in the group. I got my Digi-Comp I for Christmas 1970. I still have it, with the original manuals and the Advanced Programming manual...
Hi and Welcome, There's a guy who sells reproduction springs. Scan recent postings for the web address. Feel like scanning the Advanced Programming Manual and...
Does Friends of DigiComp have a moderator or list maintainer? If so, I would like to suggest that you do your best to remove blatant spammers from the list as...
I would like to see the advanced manual if you would scan it. I previously posted the manual that came with it, but never saw the advanced manual (the ...
I collected plastic straws for an unrelated project and noticed that the various fast-food places have different sizes. Perhaps if you carried one of the ...
Digi-Comp I's 3-bit word held 8 possible values. There are 8^8 possible functions from a set of 8 things to itself. Examples include: (a) the function...
The Digi Comp 1 has 54 places where you either install a soda straw - or else you don't install one. The soda straws are used to program the Digi Comp 1 So...
Random tube locations would result in many of the programs trying to force a flip-flop to set and reset at the same time. Forty year old plastic might not be...
