I tried the mbd in a different chassis (so a different MAC/cable/etc.), it made no difference. I'm not quite ready yet btw to do that level of board testing (need to setup the microscope, cam, etc.) and a bench PSU is the final item of kit I've yet to buy. :} Diode mode testing and relevant pin/track profiles is the main thing I want to do in the long term for this and a great many other boards. I won't be able to get stuck into this though until probably next summer as atm I'm away much of the time dealing with the estate of my late step-Dad.

However, the original mbd (the one I replaced the SCSI socket on) in the borrowed chassis is now detecting SCSI devices ok, last night I was able to reach the PROM. Turned out aswell that the disk I'd been using was faulty, which is annoying (I've just finished a 4.0.5 reinstall on another disk - thank grud I spent the time way back creating a 4.0.5 installation disk, ie. no need to bother with network installs, CDs or tape). With my own chassis though, given how it behaved with the original mbd after the repair, I think it may have a problem with its long SCSI ribbon cable (perhaps damaged somewhere after soooo many mbd/gfx assembly removals and insertions). This suggests my original mbd repair did actually work ok, I just was horribly unlucky with both a SCSI ribbon cable that became faulty and a disk that developed a fault without my being able to tell.

So, I have a working IP6 again (hurrah!!), now I just need to sort out the gfx which isn't actually fully ok, I can see some speckly artefacts when I run things, or even just move the mouse over an icon. I probably need a replacement GR1.5.

I do need at some point to resolve the loopback issue on the other mbd so that I can still have a working system, but of course I need to sort out the bad SCSI ribbon cable too. The cable inside the chassis looks pretty firmly fixed in, bit tricky to replace. I have an IRIS File chassis stored away though, maybe that will have the same cable.
