Building a CP/M System Disk
Log from My CP/M Single Board Computer
Building a CP/M System Disk To avoid rewriting the assembler codes for ccp, bdos and cbios so that they can co-exist in the same file. I can append the i8hex files and remove the "end of file markers". To make the hex file more readable I have changed...

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...

[E1][T][M] Tetent with 1440px screen?
Log from Tetent [gd0090]
1440x1440px resolution at 125% scalingWhat the screen would look like on Tetent (but sharper). This already makes me think back to my Windows Vista on PSP days, but I'm mainly imagining the future present of quietly chilling in bed while trimming down...

In The Radio Domain
Log from Reverse-Engineering the milight on-air protocol
The first step in reverse-engineering any radio protocol is to listen to it on the air. The advent of software-defined radio makes this much, much, easier than before. For this project I've used a nuand bladeRF board and the GNURadio software stack,...

Eureka!
Log from Commodore CHESSmate Reproduction
After I convinced myself that the emulator was probably OK, I turned back to the ROM. But after I found yet another ROM image online, and it turned out to be identical to the other three, I have to rule out bad ROM as well. Just as well as I was...

Could this work?
Log from EDIDone - Disable DisplayPort Hotplug
I recovered the project file from my drive and made some changes to it. The question is, which wire goes where? I won't know for sure until the dummy plug arrives, but the AUX line is definitely used for this purpose. I even created an EDID data for...

20230222b A Tale of Two Translations
Log from ROM Disassembly - AlphaSmart Pro
There are several translation routines found during the file sending stuff that translate one character value into another one. Some we understand, like this one:F4DC sub_F4DC: F4DC 84 7F anda #$7F ; reset high bit F4DE 16 tab F4DF 4F clra F4E0...

Solar Water Heating Controller
Details from Solar Water Heating Controller
An unexpected cold shower made it clear that I need a new controller for our solar warm water heating system ("split architecture" which is typical for installation in middle and northern Europe - thanks @Saabman for helping me understand that I had...

Capturing data from the bus
Log from Harley Davidson J1850 Visual Display Interface
The first step in this project was to scope the signal on the data bus, which uses J1850 VPW, to verify I had the right source for the data, verify the voltage, and verify the signal itself. I had a few automotive 3-pin connectors lying around, so I...

V9958 - Beyond Hello World
Log from rosco_m68k
Development on the V9958 board continues apace, and after a false start due to a silly mistake in the first revision things are back on-track with a revision 1 prototype. The design is now validated and working really well. So far it's baby-steps in...

TMD-3: Turing Machine Demonstrator Mark 3
Details from TMD-3: Turing Machine Demonstrator Mark 3
Really Mike, why a TMD-3? Before I talk about what TMD-3 will be, I would like to give a brief overview of Turing machines, the TMD-1 and TMD-2 designs, and what prompted me to want to do a TMD-3. Turing Machines 101 The Turing machine was invented in...

Delta coding and some stats
Log from PEAC Pisano with End-Around Carry algorithm
With the new harvest, I estimate that the perfect and maximal orbits under m=1M is around 100K. This starts to make quite a large .h file to include in the sieve generator. Not that it's such a concern but scalability, you know.... And embedding such...
