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.




PS You might need to expand the picture view if you want to see any of the details.
