Quantar Extender Cables

 

Are there extender cards or cables to aid in Quantar module troubleshooting and tuning?? Other than some content on the W9CR website, which was very useful, I have not been able to find a thing.? ?It seems like I may end up having to use a stripped down Quantar Chassis for this purpose.
?
Thanks!

This is what I came up with, needs a little bit of refinement though on the width of the board to be supported in the chassis correctly.

I can't find any information on the socket the power supply and power amp use.

If anyone has a picture of the official Motorola set that would help a lot.

Actually, that's pretty f@#$ing clever. What I would REALLY like to find, is the heavy nylon pry-tool that M made to pull the modules out of the chassis.
What I currently use is a square wooden dowel and tap w/a hammer from the rear.
 

Also, soap the rails w/dry Ivory bar soap to lubricate.
 

Uh, what? You've got a bent up chassis then. I've never had issues like that and I've worked on hundreds of the things. The SCM and WL cards can be a bit of a pain but still don't require that level of force...

The cover plate is a board puller, FYI.
?
There's a metal tab on the backside of the board cover faceplate (the one with the Speaker).? If you turn it around, you can slip it in to a groove at the bottom front underside of the SCM and WL PCBs.? By firmly grasping the hooked faceplate, you can get enough grip to pull the board straight out from it's socket.? Don't try to lever or bend it, just pull straight out.
?
Captive metal levers like the old minicomputers had would have been better, but this is a decent have-it-in-hand solution.? You can almost get enough grip on the board to pull it with your fingers as-is, but there is really no good spot to grip it from.? This hook solves the grip issue.

I like to use the curved or straight pick from the Harbor Freight pick set, depending on which one I grab.

If the SCM card is being stubborn I've had it bend the tool on the back of the front panel.
