Official SEGA 28pin pcb scan
Post Posted: Wed Apr 29, 2020 11:28 am
I did a high resolution scan (1200dpi) of the official 28 pin pcb.
I plan to make a noramboot cart from it to develop stuff with it but before I do that I thought I make a scan of it for you people.
The only blemish is that I had to sand it down to fit it in the 3D printed frame and one of the edges is not strait/square.

The zip file contains the 1200dpi jpegs.

PS. pin 1 is /WE but on 27c256 it is VPP so that need to be changed to +5v (pin 28) to be on the safe side acording to ATMEL

Thanks for this! I love it when people go to the effort for awesome scans and archival stuff. I have some insane high dpi scans of my CDX box I need to upload still :D
