Gotek mount for Tandon TM100 replacement
Demonstrating a Gotek drive mount I created to maintain the aesthetics of the original Tandon TM100-1A drive installed in my Kaypro II.

KENBAK 1 Christmas Star
Переглядів 1412 роки тому
Christmas Minimalistic computing challenge (logiker.com/Vintage-Computing-Christmas-Challenge-2022) inspired me to implement with the printing KENBAK-1.
Kenbak-1 prints 1-D cellular automata patterns
Переглядів 9212 роки тому
Kenbak-1 was the first home computer. It was limited to 256 bytes of memory, and LEDs and switches were its only form of input and output. This project gives this uKenbak-1 reproduction (adwaterandstir.com/product/kenbak-1/) a reach into the physical world by interfacing it by light to an electric typewriter. This is printing a new generation of a one-dimensional cellular automata (known as rul...
Cellular Automata on a Kenbak-1. First milestone
Переглядів 2512 роки тому
I have implemented a 1-dimensional cellular automata on a Kenbak-1 (miniaturized reproduction), a very limited computer with 256 bytes of memory and only switches for input and 8 LEDs for output. As a first step I have implemented a 1x8 cell wrapping universe making use of the implementation at elife-asu.github.io/wss-modules/modules/1-1d-cellular-automata/ for verification that my implementati...

Using a nanoKenbak-1 to display "HAPPY HALLOWEEN" using a computer with only 256 bytes of memory and 8 LEDs for output.
Skywriting proof of concept with a nanoKenbak-1
Переглядів 502 роки тому
Kenbak-1 is a computer developed in 1970. It had a total of 256 bytes of memory and is a great tool for learning machine language. This is a proof of concept using the 8 input/output LEDs on a nanoKenbak-1 reproduction from Adwater & Stir, showing that letters can be spelled out in the air despite the limited display of the computer. I'm attempting to spell out "HELLO". The timing of my waving ...

Enigma emulated on a Kenbak-1
Переглядів 1333 роки тому
As a hobby project, I wanted to see if a 3-rotor Enigma could be implemented in the confines of 256 bytes of memory. Program and further description here: vps.wagonfort.ca/enigma.txt Flowcharts of the program here: vps.wagonfort.ca/Kenbak Enigma_Main.JPG vps.wagonfort.ca/Kenbak Enigma_Rotor.JPG This most closely emulates the pre-war commercial ENIGMA C. 256 bytes is not enough memory to impleme...

Truck snags a low-hanging power line

Cropped and shortened version here: ua-cam.com/video/Lpq31bRSzOo/v-deo.html Truck snags a power line was hanging too low. Note that the truck was not excessively tall, just the power line was hanging too low. This is no fault of the truck.
BASIC week 6 challenge on a Kaypro II
Переглядів 1013 роки тому
For absurdity, I'm displaying the BASIC week 6 "Mandelbaum" program on a 386DX, but making a Kaypro II (Z80) do the heavy lifting. The Kaypro II sends coordinates via serial @ 1200bps to the 386, which plots it on a 640x480 display. 13 1/2 hours to complete.

More info on website and program please🤖
Of course! I took down the server where the website was hosted but I'll get them reposted somewhere and update the description. Are there any particular questions you'd like answered about this? I also followed this up with a version that prints these 1-dimensional CAs to paper from a uKenbak-1, if you'd find that interesting: ua-cam.com/video/V-xcI1O2mRc/v-deo.html
Cool use for KENBAK!👍🤖
Awesome! I knew the Kenbak had no i/O ports from other videos on UA-cam. So I expected the μKenbak would have some basic interface. But that solution is just brilliant! I'm still fascinated by the fact that this is a fully serial machine.
Thank you. I agree, the fact that the Kenbak-1 predates microprocessors and had no single-chip CPU is incredible. It would have been an incredible accomplishment to design and build.
Muy buen trabajo, saludos desde España 😊😊
I think it's amazing what you have accomplished here. 👍
Awesome
Very cool. What is the constraint on the speed of processing, the Kenbak or the typewriter?
Definitely the typewriter is the bottleneck. A significant amount of time is spent in a delay loop while pressing keys so a keystroke is simulated, and again for a time between keystrokes. the Kenbak-1 is capable of doing this much faster if it had a faster method of output.
@@captaincryptogram2356 Ahh OK, very interesting. The idea to use the blinkenlights as a means of output is very cool. I think that using the LDRs so that you didn't hack the Kenbak is really clever. Do you have any thoughts on receiving digital inputs in a similar non-invasive way? I wonder whether a serial terminal interface might be possible.
@@decleA non-invasive digital input could be performed by some actuators to push the buttons. But I doubt such small servos were available in 1969 so it would be a "modern tech" solution.
Nice!
hello there captain, u got a sub.
Wonderful thank you. I'll try to get some new interesting things posted in the near future.
Very clever use of photodiodes and enhancing the kenbak-1's with output capability.
Dang clever. That type of electric typewriter would could become paper terminal with some further interfacing!
Thank you. I agree, it could be mapped out further to give it the ability to type a larger set of characters and possibly lead to some interesting new projects.
Interesting!
Thanks for the acknowledgement, I enjoyed making this work.
This is really cool
Thank you. Glad you liked it. I'm working on another one this weekend that I'm eager to share.
Could be a Pine Martin, we have a couple of them around our area.
Looked kinda like a ferret
It does indeed look like that, but bigger. The members of the weasel family that we have in the wilds around here that are of this size are large martens or small fishers. I think it is one of those two but I wanted to hear other opinions before I settled on that.
