I never knew anything about the COM2502, but I have a wad of information
(and spares) of the COM5025 - a sync serial chip from a (ISTR) DEC DUP-11
and later, the Software Results COMBOARD-I and COMBOARD-II (later models
use the Zilog Z8530).
If anyone needs COM5025 chips, please contact me. Given my rate of
consumption, I have several lifetimes worth.
