Sb: #Multipak trouble

To: all

My son was using my Coco 3 with a multipak and didn't realize that the rubber
feet of the coco came off. The multipak still had the feet. Aparently the
multipak must have got a bad connection between it and the coco and  the
multipak got zapped. The Coco boots normally with the disk controller plugged
into the rom port but refuses to boot with the multipak plugged in. All I get
is a dark screen, no vdg screen or anything. I cleaned and checked the 34 pin
connectors and especially checked the multipak edge connector for damage and
found nothing Do you have an idea what chip might have gotten zapped? I can
replace chips with a solder iron and Ic sockets, I have done them before. I
used to do that kind of work at a shop once. Could the pal chip have gotten
zapped? With the new pal chip, will the multipak work with a Coco 2? As a
double check, I tried hooking the pak to a Coco 2 to make sure the trouble was
in the pak. Seems like I remember that when the new style pal chip is put in a
"pak" it won't work for a Coco 2 unless you have a switcher socket and the old
chip. I really need the pak working because I use the Coco 3 with a Midi card
to play a Synthisizer. Thanks, Denise Ps: If I get the pak working again, I'll
replace the rubber feet on the Coco, and mount the whole unit on a piece of
plywood so this won't happen again.
