Address decoding... and how to get it right
Log from DB6502
But it just works... What I find really amazing is how small, seemingly insignificant experiences can have enormous impact on us, how they can shape our path. For me one of those things was rather not-that-important article written by one of my professors,...

Phase 8: Blow More Things Up (oops)
Log from SWD-40: a 40% scale Special Weapons Dalek
All in all, I did make progress over the weekend! I also destroyed a few things along the way.Starting from where I left off in Phase 7: thinking about controlling the Hoverboard controller directly, I want a 3.3v logic level serial interface, so I was...

We Have Data!
Log from Improbable AVR -> 8088 substitution for PC/XT
If you haven't been following the drama, feel free to scroll down to the pictures.Looking back at previous logs... And making some notes regarding measurements at the motherboard (in that previous log)... It looks like the only signal that *might* need...

Year 5
Log from Novasaur CP/M TTL Retrocomputer
The project is entering its fifth year and plenty has been going on. Here's an update on completed and in-progress tasks for the 1.0 software release, plus some future plans for the platform. Load Averages To finish debugging the kernel, some additional...

The quest for 14MHz - part I
Log from DB6502
Long overdue update...This update is long overdue - and apologies for that - but I have been really busy recently. Between family issues, failed parallel cooperative project, end-of-year workload increase and quite complex project challenge I found myself...

Through the Maze, Down the Rabbit Hole, Into the Labyrinth
Log from Prometheus A.I.
It goes something like this. PASCALCOMPILER::THREAD_ENTRY gets called. That calls PASCALCOMPILER::COMPILER_MAIN, which leads to PASCALCOMPILER::BLOCK, which in turn brings us into PASCALCOMPILER::BODY which gets...

Tl;dr thus far...
Log from Vintage Z80 palmtop compy hackery (TI-86)
The TI-86 is very hacker-friendly... Aside from being designed with users' custom assembly/machine-code/binary-executables in mind, there are also quite a few openings for hardware-hacks. I did some testing and discovered that there are 20 accessible...

Part 5: The ALU
Log from ALUMinimum
The first motivation that predated the early computers was to automate arithmetic calculation algorithms, so it is no wonder if an arithmetic unit is at the heart of the processor and the computer itself. But besides calculation, algorithms can also...

First Axis Encoder
Log from Big Ol' Modular CNC
Yesterday: FINALLY figured out the pinout of this encoder's circuit... Apparently it's just two photodiodes, two photo-transistors, and four resistors. Even most computer-mice I've seen have more sophisticated circuits, usually involving two resistors...

Component research and selection
Log from Home-brew SMT Reflow Oven
The foundational base for this project required some sort of oven. From the design perspective, I needed an oven, preferably one with a good heat-up slope, a temperature sensor, a solid-state relay that was capable of handling “house-hold”...

Research...
Log from ESP32 TNC and Audio Relay for HF/VHF Packet Radio
Where to start? There are other ways to do this. Perhaps the cheapest approach would be to just build custom cables to tap the radio AF-in and PTT pins on the Mic port and AF-out from the SP2 port, wire those directly to my computer's aux-out...

High speed AVR based EEPROM programmer (part 1)
Log from DB6502
How to lose your mind in three really simple steps We have all been there, more than we care to remember. You are in the middle of creative frenzy, writing your code as the Devil himself. Compile, link, grab the programmer. Fish out that ROM chip...

Inside the TI-86
Log from Vintage Z80 palmtop compy hackery (TI-86)
Random notes, randomly updating, for now ... RAM: https://pdf1.alldatasheet.com/datasheet-pdf/view/47125/SONY/CXK581000ATM.html 128KB, has one NC pin, pin 9, so 256K in the same form-factor might be a thing, though not seen amongst the list of related...

SD Card Interface
Log from 65c02 Homebrew Computer on breadboard
Latest Update - Optimising SD Card send and get byte routinesI have been tinkering with the SD card low level routines. It was bugging me that when I wired up the SD card pins, the MISO line was attached to pin 2 Port B of one of my VIAs. MISO stands...

Retrospective - interfacing to FT230XS
Log from DB6502
Serial connection over USB for retro computer? Why not! I was asked by someone in /r/beneater community to describe how to build USB -> UART interface using FT230XS chip, as this exercise might seem a bit intimidating for someone doing it for a first...
