Title: Amstrad DDI-1 PCB
Post by: Vyper68 on 08:09, 28 July 18
Hi
Does anyone have or has made a PCB schematic or KiKad or Gerbers zip file for the DDI-1  to possibly enable some more DDI-1's to be made and connect to a HxC/Gotek USB Drive.

Thanks for that schematic. I don't have much experience with KiKad so it's going to be interesting  :D the one thing I have a lot of is time so it's a good project for the old grey cells.

For sure it is! Had the same challenge - but there are great tutorial KiCad videos available. Some of them tell you to not use the auto-router though... which is mostly infeasible for people on a time budget  8) The auto router has its issues, but it works if you take some time to play with the spatial arrangments. For sure it is much faster than doing the PCB routing by hand.

And - don't forget to add ground plane copper, thick GND and VCC, and caps for each IC, otherwise some people go bananas and don't buy it  8) ;D
