Since I've had to get rid of my STs, I have no further need for the diagnostic cartridge I've made. The exact version of the test suite is "Mega and ST Field Service Diagnostic Rev. 4.4." Works great. There's some tarnish on the copper traces but it doesn't seem to affect the functionality at all. I haven't had the good sense to snap a picture of the main menu before selling all of my hardware, but you can see one here. I do have a few pics of various test being run, which you can see below.
I do not have any rights to the actual diagnostic software, so this is more of a "parts and labor" type of a deal. I'm thinking $25 shipped First Class (within the US).
