Retro Computing Projects: Repairs, conversions, extensions, special hardware projects.
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 Z80-MBC2 preparationAs 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 […]
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. […]
Well, it is certainly not new – and it is also not my first Atari. But from today’s retro collectors point of view, it’s my “first”. And since my last one was sold over 20 years ago, this one is my “new one” too. Bought for about EUR 20, – on eBay – complete with […]
In addition to collecting old home computers from the 80s, I am spending a lot of time in different vintage computer projects, ie. I also like to play with the soldering iron 🙂 This is usually very necessary, since most computers of the 80s do not really end up on my desk in a workable […]
