my classic

i am both worried by and for itespecially the se one its flickering and developing lines

That's not a crt symptom. Flickering and lines are caused by the circuitry driving them. The most common cause is poor solder joints. Simply resoldering with fresh solder fixes a huge percentage of display-related faults. Much of my writeup on the Plus applies generally to the SE as well (see http://68kmla.org/files/). It may help you to know that I have disassembled many dozens of compact macs at this point, and I am not dead.

So, give yourself a Christmas present and fix that SE while you're upgrading the Classic. Once you've gotten a couple of successes under your belt, your trepidation will fade away. You'll be an old hand in no time.

I'm sure there was a time when you couldn't ride a bike, but you're well past that now. And so it can be with soldering. It's easy to learn (easier, in fact, than learning how to ride a bike).

If he had no other reason for having the authority to advise you about the relative ease of working inside Compact AIOs, tomlee59's forays inside probably number well into three digits in number and beyond. But he has other reason, as you must have gauged from his posts and his other published writings.

He saith sooth. Only if you wish to talk yourself out of making the minuscule necessary effort should you resile from getting a Torx-15 driver (with at least an 8-in shank), from inspecting and soldering the SE's video-in connection, and from maximizing the RAM in your Classic. Why have such Macs if you cannot/will not come to terms with the finesse that 68000 AIOs can achieve with so technologically little? I've run 7.5 on one of my Classics, but the hybrid '7.1.3' suits it much better. Not even a million Classics in a cluster can do astronomical calculations, but they are close to the roots of personal computing for people who don't relish entering code with eight toggle-switches, and for good reason.

1-MB RAM SIMMs are giveaway material these days, and I, for one, must have a hundred-odd of them. Torx-15 bits are easily come by, and not hard to attach to a conventional flat-bladed screwdriver. Even preparation of Install floppies is not an insuperable challenge for the average determined MLA soldier.
