@mg.man …….. instead of adding an extra connector.
Use one 50pin connector for both.
Just cutout the two slot with an exacto knife….and glue one piece back in to block the space slot on the other side.
How about that?

Hey @-SE40-, will the pinouts match correctly from the board to the video, floppy disk drive, etc.? That 50-pin connector attaches to the end of the logic board, right?

I am confused. That is why I am asking.

No confusion,…😇
……. there are two 50 pin connectors now.
One is split for two connectors.
FDD and CD sound.(i believe)
Video is on the other side of the board.
All go to up the logic board connector.
Just trying to get these cables organized decently….😇

Was that the last to be identified or had you found it already?

Haven't got one handy, but there's an offset edge card (harness end on CD-ROM bar) to CD pins adapter I couldn't find in the exploded diagrams. Have you removed the CD Adapter from the harness or did you plug SCSI and power cables into it?

@Trash80toG4 100% correct, slightly different CD-rom connector/harness mount …I suspect.
In the end its just an extension cable for the CD rom.
This should work, maybe obsolete also. IDE and the blue SCSI may replace fdd and CD-rom in the end.
Thought it may come in handy some day.

Yes, because of that option……perhaps
Blue SCSI can do that also - in time-?
using diskjockey? from onegeekarmy
I have to kidnap my wifes imac for that to try out…..

iMac has not used SCSI as the older iMacs used IDE/PATA, whereas the newer iMacs used SATA then mSATA SSD. Nowadays, iMacs use the latest SSD interface.

I just checked with Blue SCSI,
and indeed the Quadra/LC 630 board is not on the list.
Next to IDE it does have SCSI 25-50 pins.
This is not an iMac.
So I may give it a try 😇

Yesterday evening I finished the final version for the cableshield layout! Next reprinted to fit…….
and I am satisfied now 🛠
48CD9A2E-8F93-47C5-9089-8264CECE88D6.jpeg

With the previous version, the left two holes on the bottomshield where only off by 0,2 mm,
and pushing it in did cause it to get stuck/bend a little.
Moved also the switch and connector
down a bit and its centered now.
This part of the rebuilding process
was a drag to get it right🙈

Ive put the AV control in the backside for now.
If all works well and its usefull,
it may be moved to the front.

@Trash80toG4 …. now the exact position is known for each connector…..how to move forward?
Where can I find these extension cables to fit?
Or must these be soldered up from loose components/old cables?

Anyone?
Sources?
Any input is welcome!

I wouldn't expect to find extension cables that short.

An old PSX or XBOX A/V cable should cover several of those connectors.

Drawing above is for a custom PCB setup. The tentacles dangling represent the wires from lopped off full length cables. Wires to be soldered into their respective thruholes on the adapter board sitting in place of the Compact Logic Board.

edit: doubtful, but you might be able to source panel mount solder cup terminated connectors?
