ICM7216D IC - arrived

[Alex [Temple-Heath List]]

Hi John,

I'm attaching the partial schematic (in JPG format) of the GP300/P110 
portable radio that depicts the connections to the power module. 
Found the schematic right here in my home computer as I suspected.

Hope that helps. Still, I will look again into the service manual, 
see if there are any more detailed spec sheets for the module, and if 
my current manual agrees with the layout of your specific module, as 
Motorola changed them I think 3 times during the production run of 
the radio. I've seen modules with fewer leads, maybe just 5, and the 
actual position and spacing of the leads is somewhat different from 
one version to the next. Model numbers of the module where also 
changed I think at least 3 times. Can't recall right now what the 
first ones came with, but then they switched to the MHW-xxx notation 
for a good while, then the very last production runs came with the 
103R notation on the module.

BTW, found this link, if you're able to contact this person maybe you 
can trade him the schematic I've sent you for the spec sheets.

Please let me know if I can be of any further help.
