This second part about the RC2014 acording to Stephen C. Cousins deals with a few extensions. I actually wanted to add a CF module to use CP/M, but I started with a few other additions first. Since the small 3-slot backplane was quite limited, the next step was the modular 6-slot backplane. SC112 – Modular […]
It’s time for an update. This is about the RC2014 system based on the Z80 CPU. This is not really an SBC (single board computer) system, but consists of several, flexibly combinable modules. During the COVID-19 crisis I am constantly working from home, i.e. I have been working from home since March 13th. Not that […]
Stephen C. Cousins designed an extended and re-worked version of the RC2014, available for ordering as kit or as pure PCB at Tindie. Cousins also operates an excellent Website with detailed information, as well as assembly and user guides. The modules from Stephen already incorporate the extended system bus (2×40 pins instead of 1×39 in […]
After last weekend’s creation of the uTerm terminal adapter, it was time for setting up the Z80-MBC2, the main CPU PCB. Creating the Z80-MBC2 As usual, the kit from McJohn was complete, well sorted and of high quality. After sorting the components I started with the usual sequence, i.e. resistors and diodes first, followed by LED, […]
Today I have started a little DIY project to build a Single Board Computer (SBC) on the basis of a Zilog Z80 CPU. SBC Projects You will find various SBC projects, searching the web. Besides Z80 based solutions, various other CPU, e.g. MOS 6502 or Motorola 6809 can be found. All are 8 Bit CPUs. […]
