How old does the Pi have to be before it is retro?
When it has a 26 pin header?
Hey I have a bunch of those, I'm Pi retro?
I have used Flashrom and OpenOCD on Pi's.
Not sure if they do GALs? And if PAL/?GALs are not retro then that line is drawn real early.
Most CPLDs are big these days or tiny BGA packages, any DIPs still around?
True. I even consider sub-contracting PCB manufacture to be cheating
Yep just like subcontracting PCB track routing to companies who had 386+387 or 486 PC's with the latest Neural routing software.
Or getting PCB artwork made by companies with cameras you can walk inside.
Or making that Artwork with Bishop tape in the latest fancy red and blue tapes.
How about a wire wrap version, manual or fancy motor wrapper?
Wire wrap is great, you can make small PCBs with many layers of wire.
Most of my prototypes had normal IC sockets with soldered wire wrap wire.
8 layer boards no problem, the fast ones only had 4MHz clocks
Only 5 Volts is Retro? 3V3 need not apply?
Microchip still have 22V10 etc.
Ouch, VHDL design and programming them, I had forgotten that part.
Ok, now that is Retro, my first VHDL designs were done on paper.
Perhaps I can used a PSoC 1 in a 28pin dip to emulate a 22V10?
How many gates are needed for a 6845?

Ok, it's official, I'm old, I knew every reference in that conversation.
PiGFX is ANSI serial terminal software developed by Filippo Bergama
Now that's cool.
