Altairduino
Sometimes you just need to get out the soldering iron and build something. Fortunately I had an Altairduino kit waiting to be built. Nice kit and easy to follow instructions. Couple of small changes to the build instructions. In order to get a nice fitting front panel I chose not to install the top panel first. To do this I held the nuts required to secure the front panel in with tape (see image).

Bus Connector
Yacc1 will be a multi-board system requiring a motherboard, really more of a basic bus-board, for cards to plug into. For my previous 1802 projects single row breakaway headers with a simple bus-board made of either Veroboard or a simple PCB had all the pins, a grand total of 3X, required.
This custom cpu project will require far more interconnects so I ended up selecting DIN 41612 3 x 32 connectors. They physically strong and will withstand the repeated insertions and removals while at the same time quite cost effective
