I was just doing some tidying up and came across a hand drawn schematic for an 8085 microcomputer that I must have design 30 or 40 years ago. I cannot say exactly when as I do not remember doing it! If it wasn't in my hand writing I would have said it wasn't me.

 

My 8085 Micro Computer Design

 

I don't really remember making this design although it is possible I made this when I first encountered wire-wrap as a method of making prototype boards. I have another diagram showing the chip placements but nothing that shows any PCB layout. I would have remember this PCB layout.

 

How times change, or maybe, how electronics changes.
