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. […]
The next member of my collection is an Atari Mega ST2, ideal for upgrading to 4MB. The Mega ST series was available in three RAM sizes (1, 2, and 4MB). The common feature was the new housing with separate keyboard. This provided the series with a more professional look. In contrast to the 260/520/1040 series, […]
The SM124 was a sensation around the mid 80s. High-resolution and flicker-free – a true professional monitor. 640×400 pixels in black and white at 72Hz picture refresh rate do not look particularly sensational today, but in the late 80’s it was. With 12 “(approx. 30cm), the monitor is not exactly big. Compared to a standard […]
The third Atari 1040ST of my collection, is (similar to the first one) again an STFM, so the version including the RF modulator.
For reasons that I do not remember anymore today, I bought two more 1040s shortly after the first one. At similar low prices as the first device (EUR 20, – to 30, -), but this time without a monitor.
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 […]
