I replaced the 1k current limiting resistors with 10k resistors and it's much more bearable to look at now. It may not come across in the photos.

I haven't uploaded a schematic just yet since I'm still making some small changes with components. But here's the LED driver. R1 is now 10k.

Next I need to check the polarity of my DIP switches. I want "up" to be "on" like in the Altair. Which means a short on the switch. I think that means I need to install the switches upside down, but that's ok.
