@tubetime 48 layers! How thick is that board?

@tubetime Allegro (and Cadence? Schematic capture) was my first tool for making professional PCBs. It was what Sun used for hardware design. Eventually learned Eagle so that we could do more in our department "under the radar". Our Allegro "tape out" had to go through a PCB department and generally had long delays whenever hotter projects had priority.

@tubetime I can still remember laying out boards at 2x or 4x scale with semi transparent red and blue tape. Yes, really.

I should get a colonoscopy - oh I forgot I already did.
