Here are some pictures:
I will publish the diagram with all errors corrected later.
I am still struggling with the 2 MHz. Yesterday I found out that the VIA can be access at 2 MHz, the VDU board works for about 90% (there are appearing random characters during scrolling), the FDC seems to work without any issues and the WiFi board fails. All I/O access is at 1 MHz while the CPU runs at 2 MHz between I/O cycles.
This is still a puzzle to me .... Image may be NSFW.
