I have very fond memories of using and building 8-bit computers during the 1980’s, so I’ve been following Spencer Owen’s RC2014 modular 8-bit computer project with some interest. For those interest the RC2104 is a simple but very modular 8-bit microcomputer based around the Z80 microprocessor.
In its most basic form it uses a number of single row 40-pin headers (or sometimes a 39-pin header) to make a computer backplane and which takes various “computer” and add-on cards to build a system. The add-on cards currently have a choice from various Z80 CPU cards, a 6502 CPU, various sizes of RAM and ROM memory cards, serial I/O and digital I/O cards.
I was fortunate to meet Spencer at Maker Faire UK back in April 2017 and chat with him first hand about the RC2014 project and he was very open and enthusiastic about sharing all aspects of his project. So much so, a small community of fellow builders has popped up and added to the project with their own add-on cards.
I’ve put together a short list of RX2014 related web-sites:

As promised in my post of 15th October, here’s some screen shots of Manic Miner on my Xmos XC-2 based X-One console. So far I’ve only coded level 1 and I need to add code for the SNES controllers and game play and off course the rest of the 20 levels to finish it off.
The graphics were hand coded by extracting the pixel data and colour attributes for the first level from a Manic Miner ZX spectrum binary. A very mandraulic process involving switching between two editors and a couple of editor macros but it got the job done. I used Andrew Broads and Icemans (Chris Wild) excellent web sites for the screen layout information. The video engine is Yvo’s VDP for the XC-2 which provides up to 2 backgrounds and up to 32 sprites (8×8, 16×16, 32×32, 64×64 etc)
Watch this space more to come.
