The display and keyboard have to be connected to the CPU tower or it won't have any purpose other than looking pretty.

So I need to bring over the databus, control signals and power to the latches and the transceiver on the keypad/display unit.  Initially I thought about just soldering cables directly onto the tower and then have a connector at the end that plugs into the display, but that didn't feel right.

Soldering a pinheader onto the databus is easy and fast enough even as the deadline is approaching quickly.

Then it was just a matter of making a short M/F cable...
