I draw my circuit using Kicad

Never let an opportunity to learn go to waste, I say. I installed Kicad 5.0 on my system and started using it to draw the circuit. The learning curve is steep, I have to consult the Internet for puzzling problems, but I get the hang of it. Being a stickler for a neat diagram, I modify it a lot to make it neater. Bus lines in Kicad are great.

I will be using a 2816 EEPROM for testing. This has 24 pins instead of the 28 of the 2764, so on a paper copy of the diagram I write the correct pin numbers in pencil. Even so I make some mistakes that I correct after some testing with a continuity meter.
