Projects



I received the classic (full monty) kit in the beginning of February 2018. I had been looking at this and similar kits for a long time, but was not sure if I was able to make it with my poor soldering expertise. But in the end I ordered, received and assembled it. And as I feared, it didn't work (not a surprise). During the next months, I tried everything to get the system up and running. And I also purchased additional modules and kits. In the end, with all the new bits I managed to make a working system but not with the original classic modules. I eventually located the fault in the original modules to the serial module. I decided to revive the classic kit, since I had all the components, designing and making new pcbs was the goal for one of my first projects; making the "neoclassic modules".

The next, project was to house the neoclassic system. This required the design of a backplane (#06) which fitted in the housing. It has been a self contained computer with power internal supply, and keyboard and video connection thanks to the Raspberry Pi Zero Serial Terminal.

The "Basic" project was initiated to reduce the number of modules in the setup, running the Z80 cpu at 20Mhz (why running slower), and the serial interface with its own clock giving maximum performance. In addition, I designed a combined 64k banked ROM and 32k RAM module. This has been a continuous project, going through several iterations, trying to optimise but also simplify the design. I have also developed this further in memory modules containing 64k RAM and switched ROM for running CP/M.

Housing the RC2014 PRO has been another project which I am very proud of. Together with Marco Maccaferri's Video and Keyboard Module, it is a self-contained unit, running CP/M.
