       Platform: 48-volts (probably)
       Project:  
       I'll attempt to reverse engineer and document The Drof Computox, an
       electro-mechanical noughts and crosses machine.  It seems to have been
       built by a hobbyist from telephone exchange parts perhaps at some
       point in the 1960s.

       Platform: Microprofessor MPF-1
       Project:  
       Previously, I built a graphics card for the MPF-1B. So far it has done
       text output and Mandelbrot fractals. For RC2025/10, I want to see a
       rotating 3D cube on it! The code already exists, but needs to be
       ported to the MPF-1B and use the GRAF-X "VDP" instructions instead of
       driving a graphics LCD display. Also, the GRAF-X hardware will need
       double buffering, requiring a larger MCU - the plan is to switch the
       ATmega 644 that's currently used to an ATmega 128 which should have
       enough RAM for that.

       Platform: Midway 8080 hardware
       Project:  
       I'm still a software guy, so the challenge for this year is to make a
       2048 game which will run on the Midway 8080 hardware, a black & white
       arcade system. My plan is to read the documentation, write the 8080
       assembly code, assemble it and run the binary on MAME.

       Project:  
       Determine how good AI is at writing code for languages supported by
       the VAX/VMS operating system.

       Platform: gopher
       Project:  
       I need to finish updating results for RC2024/10, send out prizes, and
       post everything on the web and gopher sites. Shameful penance for
       putting it off so long.

       Platform: Radeon R500 ("X1000 Series")
       Project:  
       Radeon R500 will be 20 years old as of 05 October 2025, so it now
       qualifies for Retro Challenge.
       The primary/minimal project goal is "draw a triangle on a Radeon R500
       via direct memory-mapped hardware register and texture memory
       accesses". This means no Mesa, no `radeon` kernel module, and
       certainly no OpenGL or Direct3D.
       Compared to other graphics units I've worked with in the past (Saturn
       VDP1, Dreamcast Holly, Voodoo 2), the rabbit hole for R500 seems
       significantly deeper, considering this is the first graphics unit I've
       worked with that has programmable vertex and pixel shader engines.

       Platform: RC2014
       Project:  
       This year, I want to interface a classic Nintendo NES / Famicom joypad
       from 1983 to my RC2014 computer. There are 8 buttons on the joypad,
       but only 7 pins on the connector to the console. This means something
       interesting is happening to send data to the console from the joypad.
       This project will involve designing and building both hardware and
       software.

       Platform: Minimalist Europe Card Bus (MECB) / DREAM 6800 (6809)
       Project:  
       Following on from last year’s 2024 RetroChallenge CreatiVision
       re-Creation project, I’ve been planning a re-Creation of the DREAM
       6800 computer from the late 1970’s, using my flexible and configurable
       MECB based 8-bit retro computing platform.
       The DREAM 6800 was published in ‘Electronics Australia’ in 1979, and
       was my first hands-on microprocessor experience, as a young teenager.
       The original DREAM 6800 was inspired by the RCA COSMAC VIP system,
       which also ran a CHIP-8 language interpreter with a chunky graphics
       display.  This combination was ideal for coding early video games.
       For my DREAM 6800 re-Creation, I intend to move on to the 6809, which
       was introduced around the same time.  I also plan to enhance the
       original 64x32 graphics to also provide a higher 128x64 resolution, as
       was also envisaged by the original creator.  In addition, I also plan
       to include other enhancements inspired by recent retrospective
       original design discussions I’ve had with the original DREAM 6800
       developer, Michael.J.Bauer.
       Otherwise, I plan to remain true to the original DREAM 6800 design
       intention and function, to re-Create the original DREAM 6800
       experience.
