No PRAM BATTERY == dead PRAM battery. Do the one thing everyone frowns upon with a working machine: power it on for a few seconds and then toggle it off and on quickly. That should leave enough juice in the board for it to boot :) (it works with my PM 6100 and my performa 536cd)

However, this olde mac has been sitting unused for about a year, and when I fired it up a couple days ago just to see how it was doing, it chimed and seemed to be booting up but has no video. In the old days I would have known the sequence to troubleshoot, but now I can't decide what to do. I seem to recall that a dead PRAM battery can cause the macs to lose video, but having no PRAM battery at all does not - so I removed the PRAM battery, no luck. What are the next few steps? Re-seat the RAM? Remove all the fun stuff (accelerator & combo card)? Then what?
