The RC2014 Classic ][ is the evolution of the original RC2014 Classic. It is a modular Z80 based retro computer kit which evokes the spirit of home computers in the late 70s and computer revolution of the early 80s. It is not a clone of anything specific, but there are suggestions of the ZX81, UK101, S100, Superboard II and Apple I in there. #### Specification - Z80 CPU - 8k ROM with Microsoft BASIC and SCM Monitor ROM [1] - 32k RAM - 7.3728 Mhz - 6 pin FTDI compatible header - Connect over TTL serial at 115,200bps - 8 slot backplane with 3 free slots - Standard RC2014 bus for use with many RC2014 compatible modules - Power from FTDI cable or 5v barrel jack - Low profile (half height) module form factor #### Classic vs Classic ][ The original RC2014 Classic was designed in 2014, and having sold over 1000 units, has been the most popular kit in the RC2014 lineup to date. Whilst it is a great kit, there are opportunities for improvement. The RC2014 Classic ][ uses a consistent module form factor for all modules, all oriented the same way around. The PCB layout is electrically and visually better, with a generous smattering of decoupling capacitors. It comes with a better assembly guide, and easier to follow schematics too! #### Kit Level - PCB Only (No backplane) - Just the CPU, ROM, RAM, Serial and Clock/Reset PCB - PCB Only (Inc backplane) - Full set of all 6 PCBs - Full Kit - All PCBs, headers, sockets, passive components, ICs and printed assembly guide #### Optional Extras If ordering a Full Kit, you may wish to add extra modules. These options work out cheaper if ordering from this page, as well as saving you postage! (Of course, more modules are available. Please see my [Other Products](https://www.tindie.com/stores/Semachthemonkey/) for the full list) **Digital I/O Module** Let the RC2014 interact with the real workload through it's 8 switch inputs and 8 LED outputs.

Most USB to Serial adapters will work just fine too, but if you don't already have one, why not add this USB CDC Serial Adapter by [8086 Consultancy](https://lectronz.com/stores/8086net) to your order ![enter image description here](https://rc2014.co.uk/wp-content/uploads/2020/01/IMG_20200103_171307.jpg "5v USB CDC") Or buy direct from the creator [here](https://lectronz.com/products/uusbusb-c-cdc-serial-adaptor-5v) - [1] SCM is [Small Computer Monitor](https://smallcomputercentral.wordpress.com/small-computer-monitor/) written for the RC2014 by Steve Cousins RC2014 is a trademark of RFC2795 Ltd.
