Non-clone “blue pill” modules are becoming increasingly expensive – would you believe that they actually cost *more* than the faster and newer module for F4 BlueSCSI? This chip shortage is weird, some things are crazy expensive and other newer things haven’t changed much in pricing.
Both through-hole styles of BlueSCSI (mainline and F4) have passed testing successfully. They use only a few surface mount components: The microSD slot and capacitors for the active terminator (large capacitors which ought to be easy to hand solder with a set of tweezers). After a mounting bracket is designed, the mainline bluescsi design will be released on GitHub.
The eMate RAM/Flash expansion is proving to be somewhat tricky. The DRAM side of it (system memory as the Memory Info pane calls it) seems to be working. But the Flash (storage) side is not recognized. I’ve ordered another prototype PCB and set of flash chips for testing.
The Mac Portable project has made a little progress. It looks like the connector footprints are correct, so it’s really a matter of trying a production run to see if they work. This is the recreation of the flex cable for the official backlit screen upgrade for the original mac portable. Pretty tiny target audience, but useful nonetheless.
