Thes pictures below shows how the ButtonBox2 looked when it was built on the "old" PCB. This was before the more general PCB was developed, so this PCB could only be used to build the ButtonBox2 CPU-card, nothing else.

This picture shows the "old" CPU-card PCB with all components mounted (Atmel AT90S8515 CPU, 74HC4066, PC/keyboard connectors, 34-pin IDC connector for the connector-card and the 6-pin IDC connector used for downloading of software to the CPU). |

Here is the same CPU-card shown directly from above. |
