Steve,
It's a slightly reworked 6821 that better matches the electrical
characteristics of the keyboard interface.
They used to use 6822 chips for that same reason back in the CoCo 1 days
If you blow up the XC80652P a 6821 or 6822 is a drop-in replacement. (well,
a desolder and drop-in, most likely!)

All-
I have a coco2 wih 64K that is built on a PCB with number 20261058.
There is a large 40 pin IC that I cannot identify-- it is labelled XC80652P.
Can anyone help identify this?
Thanks, Steve
Brought to you by the 6809, the 6803 and their cousins!
