Performa 6214CD not outputting video to a VGA screen.
So my Performa 6214 won't output video to my VGA screen. I know this adapter is good and it worked intermittentley on another screen, the screen I am trying to use is a 15" 1024x768 generic screen.
I have some CRTS that are not apple that I can try. But I'd like an LCD. The machine makes the bong sound, and everything powers on A OK

Another thing I just thought of...when old Macs run at 640x480, they traditionally like to run at 67 Hz (the refresh rate used by a lot of Apple displays). This works fine on just about all the VGA CRTs that I've tried, but I'd hazard a guess that some VGA LCDs may not like it, so maybe that could have something to do with it. In the event that that is the problem, your only two choices are to either use a CRT, or get an adaptor with DIP switches that can force the Mac to run at 60 Hz.
that is true, most decent lcd's will let you get away with 60-72 hz but usually in the standard form of VGA, whereas multisync (most after the mid 90's) vga could handle pretty much anything within its range (analog, gotta love it)
I have a "model 1" nec multisync, it handles ttl monochrome to RGB to 800x600 24 bit svga @ 58hz (and it really hates that) but my year 2000 20 inch mitsubushi lcd freaks out at many fullscreen dos modes, and even standard text mode is weird while also being cut off on the left

Just as well the machine is a 6200 series, which is basically a 68040 motherboard with a PPC stuffed in.

A 6100 can be encouraged with a double-tap on the power button.
Not really a myth. Back in the day when these boxes and the 6100 alike was top of the line, several varieties of macs would not boot up with a dead cmos battery installed. Especially if the unit was unplugged from the wall. The power supply on sensing models(no on/off button) will keep the system clock going and the battery is not needed so long as the power from the wall is not interrupted. Once the unit is unplugged for a few minutes thou, it will often fail to show any video. The 6100, and other models that used an on/off switch relied solely on the cmos battery to keep the pram alive and the clock active, so these units would simply not show any video after the chime unless, like was said earlier, a double tap on the power button was used, or a new battery was installed.
Heh, we use to get so many free macs back then because people failed to realize that the unit required a cmos battery. Half the reason I have so many old world units in storage because people would just abandon them, pop in a $15.00 battery and wala! But yes, some units will boot with no cmos battery installed, just how it goes I guess, it's been so long since I worked on these boxes with system 7, the good old days.
