I have a few Turbo Mono slabs with the v74 ROMs in them. They boot and work fine with the VGA adapter cables I had made... but only for non-ADB. When I connect the cable to an ADB sound card and ADB keyboard/mouse, the devices aren't seen. Has anyone experimented with this kind of setup? I'm wondering if there is some difference in the DB19 wiring for ADB... I don't remember there being any though.
I remembered an old posting that I found again via Google:
"For the mono slabs, there are monitor cables that support only non-ADB (1352.XX), and cables that support both ADB and non-ADB (4535.XX)"
So there seems to be a difference.
Pin 7 is needed for ADB and is not present on gen1 cables. Full pinout here:

Barcher,
Out of curiosity could you run the driver performance benchmark on your system once you get it running with SCSI2SD V6?
The tool can be found in the files archive:

A related question - I have a color ADB slab, but only a mono ADB monitor. Can I use that without any issue? I haven't tried it yet; I would assume it would be OK, but figured it was good to ask!

That won't work without modification. The monitor will expect power and a different refresh. Additionally the connector is different.

I have not yet found my v6 after my move. I can post if it turns up.

Should the 1352.XX be 1532.XX?
Ahhh. Thanks for that. I didn't remember there being a difference, but I guess there is! When I had my Y cables made up I must have missed it (it was like 7 years ago now).

I just checked a 1532.02 cable and it seems pin 7 is connected.
