This is not the case for any of the Hitachi or Sony chassis that Sun used in the -3 and -4 days; all of these have sync limiting circuits which prevent any damage from out-of-sync conditions. The Hitachi chassis units may make fairly ugly noises when the sync limiter cuts in, depending on the state of several caps in the circuit, but these are relatively harmless. I can't imagine too many people with a -2 vintage monitor wanting to use it, and those that do probably get what they deserve. 8) mike
