Working on an old WOZ proto-type that had hard-drive issues. I have that settled out now, but there was no way to save the version that was on the drive. It was running a version 1.07 (not sure if that's a special proto version of 1.07 as most images I've seen of prototypes have a P in the version "43P" for example). This machine was made in 2013... The version I put on the new HD image was the current version (7.04). It will boot and run... but it keeps giving me a warning that the coin door is open, but the solenoid numbers in test line up with what's on the PF. Some switches aren't read correctly (the coin door warning, left loop entrance, etc etc), but again... proto vs production. If anyone has a few backed up HD images for the prototypes I'd really appreciate a share.
I've called JJP and they said they didn't save anything from back then.
