The Retrobrew ECB is a great series -- 160mm x 100mm. Virtually all through-hole construction. Software is great. I have maybe 25-ish different CPU and peripheral cards. For the CPU, I have a 65816, Z80, 80188 and 68008. I've designed a couple of cards for the series.
I have an original, first-run N8VEM ECB SBC. Such a neat little machine. I love in in spite of all that awful through-hole crap. ;)
I'm working with John Monahan on getting this working with his SBC188, which is an 80188-based SBC that runs MSDOS. Right now, we're figuring out the DMA part since the '188 kind of stinks at it.
That will be a neat board; I'll grab one when you folks finish it. Good luck with your DMA issues. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
