Performa 580 - TV Video system compatible ?

[KnobsNSwitches]

Does any one know if the 580 is compatible with the 600-series TV/video system? 

It seems it's based on the 600 series board, but I can't find out definitively either way if it works with the TV.

You can put the video input board in, but the 580 doesn't have the physical space needed to house the TV/FM tuner card, which I believe was in an area above the motherboard where in the 580 the hard disk probably is, if that system is arranged like the 520-575 are.

This is exactly what i'm trying to find out, thank you. Places like everymac mention it's compatible, but I haven't discovered from any one who knows for sure.

I couldn't find the dev note, but the repair manual, here http://tim.id.au/laptops/apple/legacy/lc_580.performa_580cd.pdf says that you can put the video card in, and a video out board, which is mainly to mirror to a projector, but does not mention tuners. I think the tuner connected to the video board but in the 630, 5200+ and 6200+ the tuner (TV or TV+FM) sits in another bay elsewhere in the machine that the 580 doesn't have.

One thing you may do if you're interested in having NTSC or PAL tuning is look for an ATi XClaim TV tuner. On the beige G3 it was originally "for", that board plugs into Apple's special 7-pin S-Video connector, and then into a regular audio-in jack on the computer. The s-video connector provides power to the tuner. I don't know if there's a break-out cable available.

The other-other option, of course, is to use a VCR. or other tuner-having device to tune.

Looks lik it might need a cover plate that would hold the tuner itself. Is there enough length to the ribbon cable to unplug it during a drawer removal. That might be one reason besides economies of scale for the late 630 series to have had the PCI cutout of the 6360?

 

[Cory5412]

On the 6360, the need for the "external video connector" was removed by the chassis providing a monitor port. That is probably enough space for a PCI card in teh space where the external video connector port is.

On the 5200+, the external video connector is another space on the back of the machine, the same way the TV tuner is on all of these machines.

So, if you don't need the external video connector, and the tuner itself fits, then you may be able to just put it in the External Video Connector area.

Officially though, the External Video Connector is for a second monitor or a projector for presentation purposes, and the LC580 can support the video input but not the TV/FM tuners. (I think there may also have been an analog NTSC output option for the External Video Connector.)

If the medusa mess of the 580 has an IDC-10F connector on a ribbon cable long enough to extend 3-4 inches out the back of the case you could be in business. Installing the Tuner Board behind that cover plate on the drawer or jury rigging it otherwise it will most likely work fine. It'd be one additional step to unplug/plug in the connector when removing/installing the drawer.

Ports and Pinouts has some whackiness about the drawings and some are just wrong. The 630/640/6200/6300 diagram has the the lower, extended section of the 5200/5300 with F-Connector opening below the sound ports labeled and the top bar of the 6360 with the Tuner Bay unlabeled next to the Video port in the same drawing. They all show the drawer handle upside down too, but they're port guides/illustrations, not mechanical drawings.

My 6290 had the PCI sheet metal/coverplate of the 6360, including clips and an RFI plate that looks like an ISA coverplate without the RA bent screw mount section.



They've got the PCI slot section of the 6360 labeled EVCC! If you've got the cable/connector, you can give it a try and rig up if it works.

I'd love to see pics of the front and backsides of the 580 drawer face. []

edit: if the cable's not on the wiring harness, it'd be fun to hack the connection to the mobo. It almost has to work one way or another.

Interesting they show the external video connector at all, given that the 6360 (and all the 6200-6500 machines) include a display port. The traditional solution there was that most projectors had pass-through ports. I guess you might still want the analog video out option for all those totally sweet multimedia projects you're creating.

Worth noting here is that in this 6360 drawing the only part that actually comes out is the same dimensions as the 580 board. The 580 should accept at least up to the 6200/6300 board with no trouble. I believe a relatively minimal power addition (3.3v?) was needed and perhaps then only if you wanted to use the PCI slots, but that's the same as putting a 6360/6400/6500 board in a 6200/630/5200 case.

It's the 575 and prior that use a totally different wiring harness.

Yep, I'm wondering if the 580 harness differs at all from the 630/6360 etc. harness. I've always figured the little video output board duplicates whatever interface crap that might be on the analog boards of the 580/5xxx series as there's next to nothing to it. Could be there just to have a place to hang the power button switch?

Very interested to hear if the ten pin IDC connection for the tuner is on the 580 harness?

I wouldn't put much stock in the diagrams in P&P. That External Video Connector Cover label is probably a holdover from an Illustrator file they'd done previously. For a general guide it's a very handy .PDF to have available offline.

I had to look up the 630 repair manual and I see what you mean now. I had originally, incorrectly, thought the cabling went from the video card up into the chassis to the tuner. It makes more sense it would go through the wiring harness though.

The harness is likely identical, since the 580 and 630 boards are known to be interchangeable, and the cable either goes nowhere or got tucked somewhere, or is simply deleted from the actual finalized assembly.

You were probably just mixing up the Tuner interface with the MPEG Media System's direct cable connection to the TV/Video Card.

Yep, tucked away or trimmed in the harness punchdown process would be the options, probably the former to avoid costs of tooling and separate production runs. I may just check my 6400/6500 harnesses against the 630/6360. I'm wondering now about the SCSI cable for the Cyclops-Eye-Zip. I suspect it's an untrimmed extension of the CD cable, I wonder how they handled the termination issue?

About the 580: I'm also very curious to see if the same IDC connector cable in the 630 etc. just plugs into the AB?

It would be interesting to see if the Trinitron/AB from a busted up 575 case could be installed in the 580 and what that might entail? I was halfway through TAKKYfication of one of my pair of 575s when I had to move. I got disgusted and angry mid-move I just chucked the appearance challenged 575s into the recycling dumpster. In my defense I wasn't very stable/rational at the time, badly enough that I never thought to pull the motherboards. [:I]
