[Coco] Y cable construction

[Glen VanDenBiggelaar]

Try to find a copy of Marty Goodman's book "A full Turn of the Screw" . PDF is available all over the 'net. It has complete instructions for this and many other "hardware hacks".

>Hi everyone. I'm attempting a simple Y cable. At the moment, I have a single 40 pin connector at the end of a 5.5" ribbon cable. The contacts check out good when I do a continuity test. I do not >find any shorts. 

>I plugged it into my CoCo 3 with a ROM pack connected via the ribbon cable and that works fine. When I switch to a Floppy controller, it generates a screen of garbage. The disk controller >works fine when connected directly. I attached some alligator leads from the ground tabs on the controller cart to the CoCo 3 ground tabs, knowing better ground was required. 

>Any suggestions to create a working Y cable (other than a multiple-pak!)? 

>Thanks,
