Bus display kit

Circuit board only: $16.50
Full kit: $24.00

This is the kit for building the system bus display for the original Z80 computer. This display is not part of the computer itself, that is, the computer will operate by itself without this display attached. However, when the bus display is attached, and the computer is run with the slow clock, the activity on the system buses can be followed. It allows you to see how the microcomputer system works. If the activity is a little fast even with the slow clock, you can take a video of the display and go frame-by-frame, and see what happens on the buses with each clock cycle. It is one of the educational features of this computer kit project. The schematic and instructions for building the bus display kit can be found in the computer kit manual.
