Still in development but is taking shape. I have not yet come up with the design of a PCB for the upper part of the I / O ports, as well as a shield for this one also in PCB format for it ... https://www.youtube.com/watch?v=EKXY5dlXFwU

I have made several changes, it is correct, and I think like you about the publication of the scheme but if Texelec does not give me specific public permission (I am sure they read this thread), out of respect for their work I will not publish the sources...

I like this a lot and had similar ideas previously ^^ though my motivation isn't high enough atm to actually go through with it. did you think about making it mini-DTX instead, adding another regular ISA slot below the SBC slot? there is a lot of ITX cases that have 2 card slots so you could mount …

The monochrome module works well. Conversion from PC104 to ISA should be tested with a PC104 SVGA board, coming soon... https://t.co/vs1wcOPCOf https://twitter.com/spark2k06/status/12655967 … 9744855041?s=20
