I got this 6100 from a friend for free. Lovely little box with OS7.5.3.
Found Steve Kan's site. Got me an AAUI to ethernet adapter and hey
we're surfin'! Promptly stuck in two troublesome 64mb sticks that
wouldn't work in any of a dozen other PC's. Bam! Now she's ticking
along with 132mb. Got an AV card off Ebay tres cheap and installed it.
Bah! NO image with the monitor plugged into the AV card.

The monitor is a Viewsonic that has its own little adapter (embossed
with 1280X1024 MAX). It looks like a 13W3 to DB15 adapter that plugs
into the outlet on the 6100's main board. The machine boots properly
with a beautiful image when the Viewsonic is plugged into the mainboard
video connector. The AV card has this same "Sun-like" 13W3 video socket.
When I plug the Viewsonic adapter into the AV card, the power light on
the monitor goes from green to yellow at the point in the boot sequence
when the image should come up.

Is this an OS issue?
Is this possibly a dead AV card?
Have I provided enough information?
What is this 45 pin video plug I keep reading about on 6100's? Why
don't I have one?
Will this AV card ONLY work with an Apple monitor? If so, any
recommendations?

Any and all opinions happily read.
Cheers

The 6100 shipped with what Apple call a HDI45 video outlet on the main
board which can support up to 832 x 624. You don't say, but I assume
that's what you're seeing on the Viewsonic. They also shipped with a
HDI45 - db15 adaptor on a thick 3 inch cable stub, which is normally
used to connect most Apple monitors.

A genuine Apple AV card for this model should support 1152 x 870 at 16
bit color from a "normal" db15 socket, plus s-video in/out for TV.

Where many people come unstuck with non-Apple monitors on Macs is the
"sense pins" These detect the presence of a monitor at boot time, and
its resolution. If there is no monitor connected, or its resolution is
unsupported, no video sync is output, hence your monitor light going
yellow.

There is an arcane code table relating the 3 sense pins plus ground, to
the various resolutions. Griffin & others sell adapters containing dip
switches to set "any" monitor to a Mac. If you're interested in the
details Google "Brian's Mac Monitor Summary" - the page had expired last
time I looked but an archive may have it.

I'm a little puzzled that the Viewsonic worked on the mobo socket, but
not the card. Tends to point a finger towards the card :-(
FWIW I have an Apple 1705 running at 1024 x 768 on a genuine Apple AV
card in a 6100 with nothing plugged in the mobo video out.

No it doesn't look like that, neither on the Viewsonic adapter nor the
mobo! I'd attach an image but that's not cool. The connector on the
mobo is a 13W3 like you see on a Sun box. It's not the rectangular
HDI-45 and neither is the connector on the Apple branded AV card I've
gotten off Ebay. This is very weird.
