The RC2014 Classic II has been very popular with the homebrew computer crowd, but the modular nature of it does dictate a lot of soldering, an inefficient use of logic chips and a relatively large footprint. The RC2014 Mini Z80 SBC requires only 45% as much soldering, has 3 less ICs and takes up 55% of the RC2014 footprint

- 55% less soldering than modular RC2014!
Which RC2014 Should I buy?
The RC2014 Mini, the Modular RC2014 Classic II and the individual modules will effectively give you the same computer at the end of the day. So, which one is best for you? The advantages of the RC2014 Mini are listed above, however, you should be aware that the Mini is not as flexible as the modular approach.
For example, if you wish to run at a different clock speed, or upgrade the RAM, then this can be done simply by changing a module on the Classic II.
The backplane and individual module approach has worked out better for people that want to design their own computer based loosely around the RC2014 framework, but with a different CPU for example.
If you simply want to build an RC2014 as easily as possible, plug it in and start programming in BASIC, then the RC2014 Mini Z80 SBC would certainly be the way to go.
To get even more power out of your RC2014 Mini, consider the RC2014 Mini CP/M Upgrade Kit. This boosts memory to 64k, adds compact flash storage, and even adds an extra RC2014 Standard Bus expansion slot
