This is excellent, Ian, well done! Really glad to see this project working. (Slightly greedily, I have an Atomwide 8MB board in my A5k, and was figuring out the easiest way to replace its weird mix of 80ns ZIP RAM with faster RAM... quickly gets to the point of being “easier” to RE & rebuild the whole thing with SOJ/TSOP RAM. As well as overclocking for funs, I want to vary the memory clocks to validate Other Addons.) Then, @philpem mentioned building one and I saw the thread.I've not published Gerber/BOM/etc, chiefly as I don't really yet trust designs enough to suggest others build them (I've not actually even tested this on any Alpha myself for example), nor would it be economically sane to do so for just a single build. I did get a batch of the first iteration part-populated at JLCPCB with the intent of selling, so you're best holding on to your hat just now while more testing is done and I might get a batch built to sell before too long.
Hat being held!
If you or others do a batch of populated/unpopulated boards I’m keen.Statistics: Posted by Mattmos — Fri Feb 20, 2026 5:11 pm
