OK who here has snapped the neck of a CRT during a repair attempt? Raise your hand! lol

My first classic Mac, an SE. I did this a few years ago. SNAP! I was bummed. Well I found an old Mac Plus beat up and yellow at a recycle yard and I used it's screen to fix my beloved SE.

I came very close on my Classic II while refurbing it.

I am rather hesitant now to monkey around inside my Mac now unless I have no other choice...

The only one I ever snapped was totally on purpose, with a hammer, while building the Macminitosh. Kind of fun, though!

But I'm always afraid whenever I have to use some force to disconnect the logic board of a compact…

I just did last month. I got a 20mb SE with a 68020 accelerator installed and was trying to get it apart because the accelerator wasn't seated securely in the slot. I yanked on a connector cable gently at first but it was stuck fast so I pulled it a little harder and it broke free and the momentum slammed my hand into the video board snapping the tip off the tube. Now I have to either get another tube from somewhere or attempt to put the accelerator and hard drive into my 2 floppy SE.

did this only once on purpose with a burnt out crt on a SE 1/20 just to see what happens.

its still sitting there now and waits to take the atom mobo and a 9" VGA screen

I did a couple of years ago or so to an SE/30. And I had years and years and dozens of entries and exits to Plus's and 128/512s behind me with no neck snapping. Sigh.

BTW, I found that some old B&W security monitors use the same CRT and pretty much all the same driver circuitry too. Makes me think that the original Mac team stole the analog circuitry from an old B&W security monitor....

probally, this was still during the time where the computer industry was really just snagging everything off of the shelf (the mac is about the end of that era, after that you start seeing a massive move to integration and propitiatory design to 1up the competition, and screw the customer down the road if your into ranting)

Or the Security monitor stole the Macs!

No, the Sharp 9" B&W that Trag is probably referring to dates from 1975.
