What is RC2014?

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.

What do I get?

This listing is for a kit of parts to build the Twin Port Joystick Module only. For the rest of the modules, see my other products. This kit allows you to use 2 9 pin digital joysticks with the RC2014. These can be read from simple BASIC commands or Z80 assembly language from Port 1 or Port 2. A simple test program to read the joysticks would be like this;

• 10 PRINT "PORT 1 - "; INP(1); " ";
• 20 PRINT "PORT 2 - "; INP(2)
• 30 FOR Z = 1 TO 100: NEXT Z
• 40 GOTO 10

The numbers displayed correspond to the joystick position;

• 0 = No movement
• 1 = Up
• 2 = Down
• 4 = Left
• 8 = Right
• 16 = Fire (1)
• 32 = Fire (2)

Other numbers indicate a combination. e.g. 18 is 16 + 2 or Fire (1) and Down together

Choose from 2 options:

1. Full Kit - This includes all the components to build up the Digital Input module including:

• header pins
• chip sockets
• logic chips
• resistor packs
• joystick sockets

2. PCB Only - Yup, you guessed it. Only the bare PCB!

All components are new.
