I need help identifying some Motorola chips.  They all have the
Motorola M insignia, but I can't find them in the usual places.  I
have looked in IC Master, the Motorola Master Selection Guide,
various Motorola Databooks, and Motorola Specs in Secs (data on disk).

Are they special chips made just for spcific companies?  Are they
regular chips with special part numbers (like HP chips)?

Found in a Radio Shack Color Computer 2:

SC77527P	16 pin	8423 date code		seems to be a voltage regulator
SC77526P	20 pin	8329 date code
SJ5812		3 pin	8326 date code		seems to be a transistor

Found in a General Telecomputer Telephone Extension device:

SC94023P	28 pin	8531 date code
PCS9002		(other lines found on same chip)
A61A8531
