I wish I could have bought the machine.
I've got a Sun distributor tester that's in need of a cleanup and general overhaul. The item that fails on them pretty regularly is the Xenon flash tube that illuminates the rotating arrow every time the points break. I use a delay-flash Snap-On timing light to locate the arrow instead of the internal flash tube, since the only employee Sun had who could build the flash tubes properly died back in the 1970's!
