spleen
Monospaced bitmap fonts
...Patrick Wildt (patrick@) recently imported ssdfb(4), a driver for small OLED displays in OpenBSD and needed a 5x8 font to be able to squeeze more columns and rows on those devices. As someone spending most of his time in a terminal, I have been thinking about drawing my own font for a while, and this was the perfect opportunity. To be able to test character spacing and alignment, I started to use the font in xterm, then a zoomed version, and one thing leading to another, I started creating a 8x16 version, and then bigger versions based on it. Spleen is now available in 5 sizes: 5x8, 8x16, 12x24, 16x32, and 32x64. ... -

ZAPH
Tools and Z80 engine for creating adventure games. (RUST)
...This originally began as a project to recreate an old BASIC text adventure, on the ZX Spectrum, using Z80. After developing a very simple byte code VM to handle the game interactions, I realised that there was an opportunity to use some more advance techniques, which in turn can lead to some PC based tools. -

VIC-2020 MINIMON Cartridge
Machine Language Monitor for Commodore VIC-20
...MINIMON features all commands usually expected from a debugger/monitor: Memory dump and edit, Register dump and edit, Execute code from monitor, Direct Assembler and Disassembler (all documented opcodes of the NMOS 6502), Transfer/Compare/Fill/Hunt in memory blocks, Use of breakpoints with the BRK instruction, Load/Save/Verify with any storage device.

breadcomp80v1
An 8-bit puter on a breadboard
...This was supposed to be nothing more than a practical joke which quite unexpectedly worked out. It is not optimized (never meant to be), the CP/M3 port working on it is very crude and the bit-banging SPI over AY's I/O ports is terribly slow when it comes to accessing the SD Card adapter (C:). There are several awkwardness in the design, e.g., the first occurence of the ~HALT signal is disconnecting ROM, leaving only the RAM to be accessible by the CPU until RESET (actually, it's this feature that made CP/M bootable on it!). Of the 128kB of available RAM, only 96kB can be used, the upper 32kB is always the same (CP/M's BDOS and BIOS are there), the lower 32kB can be banked on and off by the CP/M BIOS. ... -

CaChars
Graphics mode console I/O for the TRS-80 Color Computer
This is an add-on for the CoCo Extended Color BASIC that implements 51x24 and 64x24 text screens. All operation of the BASIC interpreter works naturally. It is developed in 6809 assembly language. It may be assembled with LWTOOLS (http://lwtools.projects.l-w.ca) under Linux, or with Windows cross-assemblers such as Chet Simpson's CASM which is included in RainbowIDE. In order to build a disk image, you will also need the Toolshed utility suite.... -

QuadRay-engine
Realtime raytracer using SIMD on ARM, MIPS, PPC and x86
QuadRay engine is a realtime raytracing project aimed at full SIMD utilization on ARM, MIPS, POWER and x86 architectures. The efficient use of SIMD is achieved by processing four rays at a time to match SIMD register width (hence the name). The rendering core of the engine is written in a unified SIMD assembler allowing single assembler code to be compatible with different processor architectures, thus reducing the need to maintain multiple parallel versions. At present, Intel... -

spectrograph
The program analyzes sound when you talk into a Headset microphone
...The complete source code is included as an ASM file in 2 copies, one copy is ready for assembly with the Qeditor of free MASM32 package, and the other copy is ready for assembly with the free FASMW assembler. Using the ASM file one can try to make improvements to the sound-analyzing. I have removed from it one word which was triggering a false positive in Avast! -

Ancient Linux on Windows
Building and running ancient Linux on Windows
While I may have started with Linux 0.11, I've expanded this to include several older relases of the Linux kernel that you can cross compile from Windows, and run on Qemu. I've managed to get the older versions of the software tools running on Windows, so that there is no major invasive source changes, outside of either broken drivers, or massaging the makefiles to find things in the new paths, and calling the appropriate tools where needed. -

HelloSilicon
An introduction to ARM64 assembly on Apple Silicon Macs
An introduction to assembly on Apple Silicon Macs. In this repository, I will code along with the book Programming with 64-Bit ARM Assembly Language, adjusting all sample code for Apple's ARM64 line of computers. While Apple's marketing material seems to avoid a name for the platform and talks only about the M1 processor, the developer documentation uses the term "Apple Silicon". You need Xcode 12.2 or later, and to make things easier, the command line tools should be installed. ... -

amiga-label-maker
A label maker program for 3.5" floppy disks for the Amiga written
A label maker program for 3.5" floppy disks for the Amiga written in 1989 using 100% assembly (Profimat Amiga). Back in those days, it was all about floppy disks. Of course, the floppies came with some stickers to write down the content of the disk but I wanted to use my shiny new 24-pin printer so I wrote this little utility. It worked best using some "Zweckform" labels back then. I can't tell if there are still available today. You can add an image from a selection of images shown here to enhance the overall look of your floppies. Apparently, the program works still nicely inside WinUAE and even the printing works if you setup the printer emulation (I recommend the EpsonQ 48 dot printer). -

...The game itself can be found for free on Steam. The graphics of the game are not open source and may not be used in any commercial projects. The music and sound effects are public domain but I would appreciate credit to "Roy Davis" if you use any of the music. He was my father and he passed away in 2011. The music and other stuff is in GOTstuff.zip. Sorry, but I cannot offer any support.

zxmmcfid
A ZXMMC mass storage device FID driver for CP/M
...Although ZXMMC device is available on the market for years and it works well with +3e firmware, partitions created on MMC cards could not be accessed from CP/M world. At some point it became so frustrating, I decided to write FID driver for it. It's not perfect, but it works surprisingly well. For list of limitations, build instructions and more details see the source code file. -

NitrOSX
An alternate repository for NitrOS-9 geared specificly for the Coco 3
An alternate repository for NitrOS-9 geared specifically for the Tandy Color Computer 3 and it's Emulators. This is NOT part of the "Official" NitrOS-9 repository. It is a private fork for my personal builds only. With this project, I hope to eventually bring the build process back to the Color Computer once again without using "Cross Compiler" or modern tools. The initial effort will require the "LWtools" and "ToolShed" cross compilers until I stabilize the code back to a form which will compile entirely on the Color Computer using NitrOS-9 assemblers and compilers. -

WinCMOC (M6809 C Compiler)
A C Compiler/Editor for Retro 6809 Machines (Colour Computer/Dragon)
WinCMOC v0.6 is here! So many new features, I cant remember them all. Please uninstall old versions before installing. This is a port of the CMOC compiler (written by Pierre Sarrazin) to Windows. Currently CMOC does not support linking, so, I've written front end tools which edit CMOC's output so that it can be assembled and linked via LWTOOL's. A simple C editor in included which makes it easy to compile/build and run the xroar emulator. -

AntennaTuner
A remote symetric antenna tuner using switched relays.
I decided me to use I2C-Bus Expanders instead using an ATmega 1284p and direct I/O handling in the expanding capability of this concept. If i need more I/O or and ADC, RTC, Temp-Sensor or ever, i need just 3 Lines to join the hardware extension to the bus. -
