I talked to my local Zilog rep.  Of the Zilog distributors he gave me,
I tried Newark and Lex (800-833-3557).  Newark didn't have the Z84C13
IPC chips, and would require a large order for them to get them,
plus a long delay. Newark can do VISA, and carries the "standard"
Zilog chips (but so does Jameco/JDR, probably at a lower price!!).

Lex has the chips in stock.  I have placed a order.  They can do COD,
but no VISA.  They do have a $250 minimum order.  I paid about $18 for
my Z84C1310VEC (I think that is the proper number) chips.  They are
being shipped from San Jose.  There is also a 6Mhz version of this
chip.

As for Zilog SIO/SCC autobaud code, I'm still looking.............
