in reading the previous posts, it appears a few people have discussed making a copy of a digicomp 1. someone even posted some .dxf files and said that they...
I'm aware of the emachineshop site. Probably very depandable. But I did a very encouraging test, making a mold and then casting in polyurthane, I think. As a...
Hi, Paul So, how many pieces would the whole DigiComp take? I might be interested in sharing the base cost and a few sets. Keep me in the loop, OK? --Paul...
@paul w note that the dxf files that I've uploaded was to create a model to find out how the DC was suppost to work, i.e. the tubes in my model didn't allign...
can someone measure the nominal thickness of the various pieces (clock/set, reset, flip flop, slider shelf, rod bearing top piece, top, sides, gussets,...
I'm noticing that a large number of people are concerned about exact exact precise meaurements for the Digicomp 1. Someone said the scanned images are not...
I've measured the thickness of various DigiComp I pieces - they do seem to vary from one end to the other, anything in the range of 0.070" to 0.079" would...

The Terak 8510 was the thing that ran the UCSD Pascal P-Machine, right? Wow, I spent many hours waiting for that thing to compile a program, while it swapped...
Not to get too far away from the DigiComp (I REALLY would like to buy one or build a replacement!) but I have an 8510/a with the large chassis/2nd 8² drive...

Although I didn't see any 8" floppies there tonight, it seems like a good place to watch for some. http://marketplace.vintage.org/ -Bob S. In a message dated...
... I have lots, probably several blanks in there, but they're all 20-25 years old and I'm not sure how many of them are any good anymore... I really need to...
... Yeah, that's the one. Complete with a whopping 360x192 bitmap display, of sorts. :) Working on machines like that really taught tight coding, didn't it? ...
Hi all, This is my first post here. I recently bought a Think-a-dot, a Digi-comp 1, and a Dr. Nim on eBay. The Think-a-dot arrived a few days ago. I have a...
Hi folks, I just wanted to say thanks for mailing out the thickness measurements; I tried building a digicomp from acetate sheets a few years ago, and it...
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 ...

... 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....
