//e Fix-Up Vlog.

If anyone cares to join me, I've started working on my contraption, and am making a boring rambling vlog on the subject.

Assembling an A2Pi card on

Assembling an A2Pi card on breadboard, since the factory-made boards are out of stock.  I'll build a real one on perfboard later, once I decide what all I want to add to it.

* Since this is a RPi 3B+ (and I plan to replace it with a Rock64 once everything is working and nothing is blowing up), I didn't connect the //e's bus power to the GPIO header.  The Pi board is being powered separately so that I don't overload the //e's power supply or burn any traces on the motherboard.

Thanks!

Thanks!

 

Nahhhh, it's not too awfully complicated (I'm not too bright after all, haha).  All those wires on that breadboard look a lot worse than they really are.  The biggest mass is just the data and address lines.  ;)

 

The perfboard version ought to be a good bit cleaner!

Nothing much to say. 

Nothing much to say.  Fiddling around trying to figure out the best way to prototype the keyboard interface.  I'm waiting on some parts that won't be here until December, and I came out 1 pin short on the microcontroller.  I guess I'll have to use a 3-8 address decoder to select rows to scan, or something.  That would free up 5 pins.
