Could I politely ask why you are not able to do so at the moment? There's a tonne of dead Macs out there and while I've gotten somewhat able to probe these things via the diagnostic mode and serial, it'd be far more helpful in repairing these machines and ultimately preserving them with a TechStep recreation. I'd be sure happy to purchase one off you once budgets permit, but I'm thinking for the future, when you're not able to/willing to sell them anymore that these things will still be unobtanium and ultimately leave more boards to being sent to the trashcan. Open-sourcing would ensure that no matter what we'd have a fighting chance of building one if needed, availability of components permitting of course.
