I have an LC 580 with the following upgrades: - Replaced original motherboard with one from a Power Mac 6500 - Added a Sonnet G3 accelerator to the 6500 board - Also added one of those nifty Orange Micro USB/Firewire combo cards
All this was done years ago and I used this computer for quite a while, so I know there was nothing wrong with any of the way all these were installed. 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?
