Awesome. Thank you. Would you be averse to me putting these and some other files that you've published into github?
Hey did you remove the quad v4 pcb from oshpark? I built a set of quads last night and had a scratched up trace and possible short between a couple of legs on the AC74 and what looks like possibly some ground plane extended in between them. Sure enough in the end, the m100 doesn't start with that unit installed. So I went to look at the pcb drawing to see what the traces are supposed to be, and it's gone from oshpark now. The other 2 units worked, so the alternative flash chip works, at least for the mininal test to switch into all 4 banks and use a ur2 rom to load dos100.co to install 0quad in all 4 banks. That must excercise about 7 or 8k in each bank briefly, since dos100.co is almost 6k. -- bkw On Nov 5, 2017 9:53 AM, "Stephen Adolph" <[email protected]> wrote: > T200 RAM PCB files are in my personal directory at Club 100. > cheers > Steve > > On Sat, Nov 4, 2017 at 7:48 PM, Brian White <[email protected]> wrote: > >> Doesn't matter to me.
