Probably the best retro-kit available
For SC126 RCBus Z180 SBC/Motherboard Kit
I really like this kit. It is a very capable system on a single board. Less overall pins to solder than some other kits and has greater functionality. Other kits too closely follow the MITS 8800 paradigm: You get it together and you have no storage and limited I/O. The SC126 has mini SD Ram storage. Quality is very high, and the CPU provides integrated peripherals. If you are trying to decide which kit to assemble, look closely at this one.
