Oh that blinkenlights panel is excellent! All emulators should have
one! :-) I'm not really into Qbus much but would probably buy a
production example anyway. I'd certainly fork out for several Unibus
devices if you make them!

One tip from someone with same issue in a parallel endeavor (IBM
System/360 panel): they look much better and more authentic with 'warm
white' LEDs. These are the ones I'm using:
