Mac LC575 dis-assembly for donor parts!

I've been looking for a hard drive and floppy drive for my SE/30 restoration, so as luck would have it I found this LC575 on Gumtree.  I offered the owner $20 which was accepted.  I hoped to get the hard drive and floppy out of it as both would make nice era appropriate replacements for the drives in the SE/30.  I'm glad to say both worked out well.  I managed to salvage a 250meg Apple scsi hard drive and floppy super-drive from this machine, both work, but in need of a clean-up, as would be expected.  I also managed to remove the internal cd-rom drive.  I haven't tested that yet but no reason to expect it won't work.  Before tearing this machine apart I did try to get it to boot, but on power up all I could hear was the dong of the screen.  The screen was just blank and no activity from the hard drive or floppy could be heard.  The only attempts I made to get it working was to check the fuse on the power board, that was ok.  I also tried the trick of switching it on and off really quickly, I'd learned this trick when trying to get my LC475 working.  If the clock battery is dead the LC475 won't start up, but switching it on/off quickly will get it to boot.  But no luck with the LC575.  Not wanting to spend too much time trying to get the thing working I just started tearing it apart.  I must admit it's quite good fun to disassemble stuff.

These aren't too hard to take apart, a few torx T15 screws on the back and the back just lifts off.  The floppy and cd-rom drives can be removed through a drop-down cover at the front, no screws required.  The hard drive and logic board come out through a cover on the back which does have a couple of screws but were missing from this one.  The internal drive/board case just un-clips from the front bezel and can be removed.  A fairly interesting case design.  Case parts and monitor will probably go to the re-cycler.  The logic board looks in fairly good shape and has the ram and cpu on it which are most likely good, so I'll hang on to that in case someone wants it.  See pics below.

The roughest part about these is they were pretty much the harbinger of the Spindler plastics. Those front panels and rear IO covers splinter like the dickens.

Yeah, I broke many of the plastic clips just using light pressure.  A combination of brittle plastic and age is pretty terminal on these things.

Re: Mac LC575 dis-assembly for donor parts!

I've always wondered what the original plan was for that little bay in the back next to the HDD. I know that there's no wiring for it, and that there's basically nothing that fits it...but I can't help but wonder just why its there. All I can think of is that Apple had some kind of plan for it and then abandoned it at the last minute.

Save the analog board and see if a person wants to use it in a CC.  They can be tried to fit and allow 640x480.

It's shaped ever so slightly different but I'm pretty sure it holds the remote for the MacTV, at least on that model. The credit card remote.

Re: Mac LC575 dis-assembly for donor parts!

If you're talking about the bay next to the HDD w/rails, looks like the AM/FM/TV Tuner module bay of the Q630 to me. What are the dimensions?

They're more than welcome to it, I'll leave it in my garage for a few weeks.

Yes, I've had a 5xx with the tuner card in that slot before. I think there was an external video port kit for it too.

Made sense to use these machines for tv and/or video.  I used these Macs at university back in the mid 90's, the Sony Trinitron tubes produced a fantastic picture for their time.

A 5xx and not a 5xxx? The only 5xx that had a Video System slot was the 580...I didn't think that the TV slot (if it is indeed a TV slot) was wired up. MacTracker doesn't list the 580 as having a TV slot.

Regardless I always thought it was a shame that the 580 had a Video System slot yet the 575 didn't - even back in its day the 580's shadow mask was a POS compared to the LC575's Trinitron.

the macintosh tv is a 5xx form factor so it must have had space for tv ability wether they used it or not.

Re: Mac LC575 dis-assembly for donor parts!

But the MacTV has the tuner plugged into a PDS-like slot on the logic board, not up in the slot.

I definitely could be wrong but I swear I had a 5xx with a tuner card in that slot.

Re: Mac LC575 dis-assembly for donor parts!

I was thinking it was a precursor to the MacTV's tuner or vestigial remnant of same. What were the relative release dates?

p.48 of Ports and Pinouts shows the Co-Axial RF Input on the backplane cover and the Service Source is equivocal, seeming to be the generic 5XX Exploded Diagram.

Methinks the MacTV got a makeshift Tuner for Co-Ax TV (only?) while the 580 got the 630's more flexible tuner box for the bay and AV Slot/board combo.

Re: Mac LC575 dis-assembly for donor parts!

There are no openings on the back panel for a TV/video slot hardware but with the apple tv out at the same time, they may have just said forget it.

The Mac TV has a coax Sony tuner board as well as composite inputs directly on the board.

(I can post pics if desired)

Re: Mac LC575 dis-assembly for donor parts!

Looks like it's a modded LC 550 board with the Sony TV tuner card added.  Has anyone seen if a Sony TV remote will control the TV part of the Mac TV, out of curiousity?

I believe I've heard they do work, I can't test this one yet until I recap it.

Yep, its a well known fact that Sony TV/VCR remotes will work on them, as will (in my experience), Sony stereo/CD player remotes. I used to use one from my Dad's HiFi system on my LC630, the CD function selector button would open and close Apple Video Player, and I could adjust the volume and use the CD controls to control audio CDs. They'll work on any Mac TV, LC580, LC630 or PowerPC Performa. I believe that Apple remotes will also work on Sony gear, though never tried it myself.

Re: Mac LC575 dis-assembly for donor parts!

mcdermd do me a favor but that 575 chassis I offloaded off you I think it had rca jack holes on the backplane, if its still there a 575 board may have had them.  might have been an education add on also.  That would be neat if it had been.

Unfortunately, I don't see the back flap anywhere back there.
