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:


'No greater love hath a man than he lay down his life for his brother.
Not for millions, not for glory, not for fame.
For one person, in the dark, where no one will ever know or see.'
