RC2014 is a simple 8 bit Z80 based modular computer. It is inspired by the home built computers of 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 here. It nominally has 8K ROM, 32K RAM, runs at 7.3728MHz and communicates over serial at 115,200 baud.
As a bare minimum, you will need a CPU, ROM, RAM, Clock and Input/Output module. The RC2014 is designed in such a way that you can build your own modules to expand it. As such, if you have access to similar components, or have specific needs, you might not need all the items I have on offer.
This listing is for a kit of parts to build the Serial I/O module only. For the rest of the modules, see my other products.
Full Kit - TTL Serial - This includes all the components to build up the Serial I/O module with a 5v TTL serial output including a 68B50 or 63B50 ASIA. You can connect this to a FTDI lead, Arduino serial pins or other 5v serial devices.
Full Kit - RS232 - This includes everything in the TTL serial option as well as the driver chip and 9 pin D socket to give you regular +/-12v RS232 communication
PCB Only - Yup, you guessed it. Only the bare PCB!
All other components are new.
Note 2: If you have fitted the full RS232 kit and wish to use the TTL serial output, you will need to remove the MAX232 IC
