Our ancient Zeiss Humphrey field machine (750i Model) decided yesterday to power on, but not to boot up. We're stuck on the blank "startup" prompt with the spinning disc. But it won't move past that. We've tried the basics several times, power cycles, and unplugging for several minutes and trying again as well. The 3.5" floppy is spinning, and the HDD light flashes and flickers as well - but it just won't move past that start up screen. Up until 2 days ago, it worked flawlessly, and didn't have any issues powering up, running tests, or shut down. I realize things don't last forever, but was hoping another here may be familiar with this behavior and help save us a very expensive call to Zeiss tech support...

TIA!
