thanx kludge for the Adapter ! you Awseome!
Thanks, and you're welcome. I really don't think I did much here. Granted I started it, gathered the information and routed the PCB, but all the important information for the (as of now) final solution came from others. TEAM EFFORT!
Regarding the compatibility with the TF cards, it's surely fixable in firmware as the adapter works with other cards and stand alone CPU's. The problem is figuring out where it goes wrong, as I think it could be anything from some IDE collision (doubtful according to Stephen) to timing issues. I don't have access to a good enough LA, so the best I could do is trial and error with custom testing firmwares.
If anyone with a decent LA would like an adapter to help figure out where it goes wrong, just let me know.
But as a concept for taking over from the A600 CPU this seems kind of complete now. I've been looking at possible mounting solutions using the hard drive mounting holes, but if I want to keep the adapter inside 10x10 cm I can only use the two leftmost holes, which means that the screws would be on the same side of the adapter. Might not work well.
I think I'll update the scematics and PCB so that the adapter works like the patched version. Without mounting holes. As a prototype/proof of concept. I think a separate PCB layout for TF on the A600 is a better option long term, but I think it would be wise to wait for a "final" version of the 53x line first to base this on. If that's the 534 or a version with SDRAM only time (and/or Stephen) can tell
