The Story So Far-- Explodophone 1.0 Part 2
Log from The Explodophone
Now for the other half. For maximum starting flexibility without taking the cost too high, I opted to go two octaves, using notes found on the white piano keys only, i.e., notes with only letter designations and no sharp or flat symbols. This means I...

FAT32 File Format
Log from OSI SD Card Operating System (OSISDOS)
When you search google for FAT file format you get tons of pages on formatting disks. It's harder to pull out the detailed format of the SD card. Wikipedia to the rescue (Design of the FAT file system). A less technical FAT32 Wikipedia page is File...

9/20/23 Update
Log from 1802 MemberChip Card
I added a link to Josh Bensadon's short Youtube video demo of the MemberChip Card. (Thanks, Josh! I've never made a video in my life, and didn't know how I was going to add one to meet the contest rules.) I now have a program to read files from the upper...

20230219a -- File Sending Speed
Log from ROM Disassembly - AlphaSmart Pro
While whizzing through the keyboard stuff, there is some special handling of some keystrokes. This is by scan code, so it's difficult for me to puzzle out what they are. One exception, though, is for setting the 'send speed'. There...

OPS ENUMERATED - Draft
Log from TIS-100 (Geiger)
This represents a complete OPCODE list with 14 Constants (int values) available and 10 Labels (byte values) available for creating subroutines. Constants were favored over Labels, but this is up for evaluation. NOP and HCF were both added to the official...

Control Board FPGA Pinout
Log from BARCO NX-4 GROUP REVERSING ADVENTURE
I might be missing a few connections yet which I'll correct as I come across them, but here is the pinout of the XC3S250E FPGA on the control board. Note that the SRAM and the Flash share an interface bus. Also note that the JTAG interface...

New Print Function
Log from Merlin
The EVE chip has a number of built in fonts. You can access them directly using the "cmd_text" command. I've added a new basic command in addition to the PRINT command - "GDPRINT"You can specify the font (#16-31), cursor position and colour, plus a string...

Running short fragment of program - but needs a lot of fixing!
Log from Let's experiment: NEC V20 + FPGA
I have squeezed some simple instructions into a 16-byte ROM that writes 0x04 into the I/O address 0x00, and repeats (http://www.homebrew8088.com/):A: MOV AL, 04 OUT 00, AL JMP AThis is then converted into machine code (https://defuse.ca/online-x86-assembler.htm),...

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...

It's not the assembler
Log from Z80 Computer
It never fails. If you get to the point where you start to suspect the Assembler/Compiler/Automated-tool-built-by-someone-much-smarter-than-you is what isn't working, then humility is sure to follow.I salvaged a Zilog 8530 SCC (UART) from an old motherboard,...
