Micro-coded controller deep-dive
Log from Custom circuit testing using Intel HEX files
In this project, instead of using a standard embedded processor and programming it to execute 3 tasks at hand (parsing HEX character stream, generating HEX character stream, and writing character stream to video RAM driving VGA), I created 3 independent...

Days 3,4,5: Eureka, sound and images found!
Log from Tsukuyomi
1. Toolchain not found After stepping away few days far from my PC for family reason, I resumed my activities on the Tsykuyomi project.So I started by reading the https://github.com/WHhkwong/SIPI_Bear_playback code and looking for a SNC7001A Toolchain/SDK...

EC or not EC: that is the question
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
For some reason, EC probes are relatively expensive. In most cases they are more expensive than pH probes, which to me seem a lot harder to make. So, I decided to make my own EC probe, as you can see below:The contacts are gold plated Studex ear piercing...

SD Card Assembly Language Code
Log from OSI SD Card Operating System (OSISDOS)
Minimal SD card code in C: /* OSISDOS.c - Minimal Operating System for OSI C1P/SuperBoard ][ */ /* SDHC card based disk operating system */ /* 8KB Microsoft BASIC-In-ROM has I/O support routines */ /* CEGMON has various hooks to the I/O in BASIC */ /*...

Improvement of the EC sensor
Log from UltraTower
It is better to read the EC sensor log before reading this one. I wanted to test the stability and accuracy of the EC sensor! So I replaced the EC probe with a fixed resistor (to mimic the resistance of a solution). The EC probe was replaced...

Production Progress: 88% Yield
Log from GAT Nametag DC27 Addon
As of today, about a week and a half before DEF CON 27, the GAT Nametag project is effectively complete. Today I've built and packaged 113 working nametags. Some failures should be easily reworkable and I will get these operational if I can find time....

Testing Germanium transistors (2nd part)
Log from Clockwork germanium
Before I can proceed with the debouncing circuit, I have to evaluate the characteristics of the transistors and choose the lousiest (debouncing is not a critical circuit). Fortunately I had built a board for manually Testing Germanium transistors. Remark:...

We Have Blinkenlights!
Log from 2:5 Scale KENBAK-1 Personal Computer Reproduction
With the wiring complete I wrote a small program in Python to test the lights, buttons, and switches on the front panel. To be clear this is NOT the KENBAK-2/5 emulator running a program (yet). As it turns out I did have to replace one of the LEDs...

Floppy Controller
Log from HP 4952A turned general purpose CP/M machine
x86 ASM is not a pretty sight. x86 addressing sucks. So I was banging my head on the wall with reverse engineering the main memory board when I figured "Hey, I have the full schematic of the floppy board, why not just use it as the main processor instead?!"...

EC firmware dumped
Log from Reverse engineering Toshiba R100 BIOS
After another long hiatus, I've come back to this project. Let's break this thing!I've etched a new board that lets me access important pins (serial TX, RX, CLK, BUSY ; RST and power lines) without having to fiddle with the previous hacky breakout board.I've...

Understanding how the computer works
Log from Apollo Guidance Computer
Fortunately most of the NASA documents are available. They can be found on-line at https://www.ibiblio.org/apollo/Documents/ The following documents are what I leaned heavily on in gaining an understanding of how this computer...
