I don't know how far away from the main PCB I can move the rom PCB without problems, but can anyone tell me the part number for the cable, which is at present about 4 inches long, so I can try to find out how long I can get them?

www.Digikey.com sell connectors & made up cables that look correct - have a look at the connector specs pdf doco on catalogue page
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=CPC40S-ND for the rom board connector.
I measured up the rom board connector on my Defender ROM board (Presumeably the same connector is used on the Robotron ROM board too.) and compared it to the CPC40S-ND connector. I used my Micrometer the check the pin spacing and sizes and the specs match.
There are also made up cables using those connectors - go to the home page
http://www.digikey.com/ and search for "C3APS-4006G-ND" for a 6" cable, and "C3APS-4036G-ND" for a 36" cable (there are other sizes listed in the table
http://dkc3.digikey.com/PDF/B092/P0036.pdf )
Can anyone confirm that the aforementioned Digikey "C3APS-4006G-ND" or similar cables are suitable for the Defender/Stargate/Robotron Rom to CPU board connections ?
Cheers.
Ok. The last post in this thread was a few days before my injury, surgery, complications, hospital stay, and all the other garbage that happened afterwards.
So I'm back to trying to figure out what I need and where to get it.
The following 40 pin cable should work between the main and rom PCBs:
http://www.digikey.com/product-detail/en/C3APS-4006G-ND/C3APS-4006G-ND/1123437
Then there is the 20 pin ribbon cable that should work between the main PCB and interface PCB:
http://www.digikey.com/product-detail/en/C3APS-2006G-ND/C3APS-2006G-ND/1123419
Now Bob Roberts sells the following:
Wms Ribbon Cable Main PCB to Rom PCB $9.50
Wms Ribbon Cable Main PCB to Interface PCB $8.50
Wms Ribbon Cable Main PCB to Speech PCB $9.50
Can anyone explain the need for a ribbon cable between the main and speech PCBs? (My boardsets do not have this).
Lastly, since I also need to crimp my own 40 pin IDE (and 20pin-whatever it is called) can someone tell me the search terms needed to find the connectors on Ebay and the tool needed to do this?
Thanks.
