Monday night?

Old computers come and go in the great circle of life. But there was an LCIII that I had that I let go prematurely. It was making weird squealing noises and the speaker wasn't working and it was acting just a little bit off, so I sold it. Then about a year later I discovered the magical wonders that recapping can work.

That said, it's still a skill with which I have very little confidence or skill.

And we’re in! Time to hack the mainframe.

It's that forest of capacitors by the sound in the top-left that stresses me out the most. So many! So close together! So near to meltable plastic!

First capacitor off, first pad lifted. Oops.

@billgoats 😅it wouldn’t be SMD work if there wasn’t a lifted pad or two!

Not going to win any awards here!

@billgoats if it fits, it ships!

Fewer pads missing this time.

Less terrible, this one.

Okay, this has been a bit more full on than I expected. It’s midnight and we’re part way done. Going to pick it up again tomorrow. Getting there though!

And massive thanks to folk like @mac84tv and @MuseumJoe who will do casual recapping streams for fun. Seeing that it's actually doable and fine and that when things go awry there's often some sort of fix is really helpful for us relative n00bz :D

And it continues…. Maaaan, the LC sound forest is dreadful! And here’s to hoping I haven’t actually destroyed anything :S

billgoats,
@billgoats@bitbang.social avatar

Aaaand... The LC is not starting up.

Fan turns on. Floppy drive makes its little noise. BlueSCSI lights up, but doesn't blink like it's accessing. Video turns the monitor on but doesn't send out any signal. Audio initialises but doesn't play the startup sound.

Weirdest of all, the lights on the keyboard just stay on instead of just quickly blinking.

LC spa treatment day.

@billgoats it's amazing how much (fairly invisible) residue leaks from the caps

billgoats,
@billgoats@bitbang.social avatar

@vga256 I did a bit of brushing and clearing and toothpick-scraping around where I’d been working, too. Some of it was a bit… dodgy. So who knows what the actual fix was 😜

vga256,
@vga256@dialup.cafe avatar

@billgoats that's a good thing either way :) i'm so glad your machine booted eventually. it took me - literally - months to get my CC fully working. i was convinced that i had a bad edge connector because the floppy drive never worked. it turned out to be one spot i had missed cleaning before i installed a new cap, and it bridged the pads beneath it - right beside the floppy controller 😩

billgoats,
@billgoats@bitbang.social avatar

@vga256 Thanks, me too! Such a relief!

And how frustratingly baffling with your CC. That’s very definitely a machine to not give up on though.

vga256,
@vga256@dialup.cafe avatar

@billgoats it's such a special machine. i wish i could show people how stunning the polished glass on the CRT is, with its weird horizontal-only bend

vga256,
@vga256@dialup.cafe avatar

@billgoats try, try again :) took me 3 tries with my SMD soldering job to get my CC to boot. was sure that i got it right every time too.

just finicky solder pads, poor bodge jobs, accidentally bridged traces under caps, etc

billgoats,
@billgoats@bitbang.social avatar

@vga256 Yeurp. The good thing is there are signs of life, so it's not completely b0rked and hopefully fixable. The bad thing is it's not actually working yet 😜

vga256,
@vga256@dialup.cafe avatar

@billgoats :) been there. also, it could be the pic, but there appears to be a blob of solder bridging legs on UD9/34064

billgoats,
@billgoats@bitbang.social avatar

@vga256 dodgy photography, probably.

@billgoats freaky!
