Can it be done? Internally the iMac G3 CRT uses a DB-15 connector (this is the one with the dead HDD), and I don't have a DB-15 display but really want to see my Macintosh Performa 6200CD in action.
 
Yes it's possible. But you must first get the CRT to power on without having the iMac logicboard trigger it on. I think it's the purple wire to ground turns in on. Performa 6200's aren't the most amazing machines to see in action. They're often considered one of the worst Macs ever made.
 
It might be wise to invest in a DB-15 to VGA adapter. The Apple made ones "just work" but are hard to find(the only one I have was packed in the accessory box with my B&W G3). The cheap ones with DIP switches will work, but often require some fiddling to get the adapter to work correctly.
 
I think it's the connector that goes to the logicboard. Don't exactly remember which one. There are so many flaws with the 5200/6200 line. The logicboard's design is hampered by the different 8/16/32/64 bit speeds all being corrected computationally by the CPU, the flaky SCSI controller, poor video capabilities, congestion between the memory and the CPU. They're just a poor performing machine all around.
 
The logic board of the iMac doesn't have to be removed, it just has to be completely disconnected from the CRT and display circuitry.

I have a genuine DB-15 to VGA adapter... It's the transparent yellowish-beigeish whateverish color one. Are these rare?

Not to my knowledge. I have 2 of them. Both of mine have switches to control the Resolution on the screen. Before i even got a beige Mac i recieved 2 of them gave one away and when i bought my Beige G3 it came with one too. NOt that rare..

Switches? Mine doesn't have switches. It just has an apple logo.

I'm talking about this specific model of adapter. Of course in general they are all not rare but I'm talking about this one.
