20230221a -- File Deleting/Erasing
Log from ROM Disassembly - AlphaSmart Pro
Previously, while rummaging for scan codes, I was correlating known behaviour with key codes. One of those keys was the Clear File key (0x56). I forgot to post about that find, but it's still worthwhile to mention the file clearing operation...

Orchestra 80/85 Support
Log from TRS-80 Model 1 on a PIC32
The PWM has been in-place for quite some time (and is used for the 'cassette sound' feature that many games use), but I had never gotten around to implementing the Orchestra 80 support, even though it should be simple. Part of the reason was that...

September 28th 2023: I can't make the linear actuator move precisely
Log from Automatic Moving Cricket Wicket
It was dumb to use a DC motor for this project. I should have just ponied up the resources for a high speed stepper. My plan was to attach a rotary encoder to the DC motor to accurately measure the number of rotations. This is not easy....First, I tried...

Soldering perfboard
Log from Earth Lander 84
I took a perfboard and soldered up power and the data/address busses of the MCU, SRAM, NVRAM and the address bus latch.I did't really care about the exact order of the bits when wiring them up, I just went for the easiest layout. I'm not really sure...

All boards received
Log from NEDONAND homebrew computer
The rest of the boards just came:I think I will connect them together through wire-wrapped "motherboard" (lets call it "NEDONAND-10" ; )All of these NEDONAND components could be tested one by one using PIC microcontroller (connected to PC through RS-232)...

Different SD card MBR formats
Log from OSI SD Card Operating System (OSISDOS)
I tried a couple of other cards and found that they have different MBR formats with no header. I noted this in a previous log. There's an offset at 0x01BE that points to the MBR. My theory is this is true for "bigger" cards. I think the reason I could...

Paper Model now Steps. Stepping algorithm optimized. 11 bytes saved.
Log from Mystery 6502 program for the Kim Uno #1kBChallenge
I was looking for a way to make the Excel Paper Model for the Z30 calculate the stepping points so it would be a complete model of the machine. The example shown below is for a rotor with a Ring Setting of 4, the 1 mark on the ring is set to the 4 position...

[T] A3 Contact Image Sensor
Log from Tetent UMPC [gd0149]
It's almost certain at this point that Leti will be over 300mm long, so only having a scanner that can do 210mm seems like a bit of a missed opportunity. Unlike A4, a handheld A3 document scanner basically doesn't exist. There are A3 all-in-one printers...

First Attempt at raw 8086/88 assembling...
Log from Improbable AVR -> 8088 substitution for PC/XT
Here we go! First attempt at assembling raw 8088/86 code...The point, here, is to create raw binary machine-code that can be directly loaded into the BIOS/ROM chip... NOT to create an executable that would run under an operating system like linux, or...

The Keyboard
Log from Anatomy of a Philips VideoWRITER
Before I start this log on the keyboard I should mention that I'm in the process of putting all of my writings and software on the Video Writer on a small website. The following is an almost direct copy of what will be the article about the keyboard......

Plasma Effect for TMS9918
Log from Game Boards for RC2014
Plascii Petsma by Cruzer/Camelot has one of the nicest looking plasma effects I've seen for the C64. Since he included the source code, I was able to port it to the Z80 and TMS9918. On top of the features in the original C64 version, I have...

New Boat, New Autopilot - using an old laptop mainboard!
Log from OpenCPN Chart Plotter /w Autopilot and Waypoints
For quite some time I have been thinking about the possibility to using a laptop to run all the heavy OpenPlotter and OpenCPN stuff instead of using a Raspberry Pi. The performance of the RPi is... well it's usable but it's not a pleasant user experience....

[T] Inbuilt A4 Document Scanner
Log from Tetent UMPC [gd0149]
Since I'm unbound by the generic requirements of "the masses" and have complete idea freedom until "the rubber hits the road", as they say, I was wondering about any additional features I could install into Leti. The requirement was that:it had to actually...

nedoPC-85-MK v1.0
Log from nedoPC-85
This one could be a standalone 8085-based computer with Cherry-MX keyboard on board, 12 5x7 LED matrices and 6 7-segment indicators with some additional indication and stereo-audio output (2 channels with 4 bit per channel): Intended to resemble look...
