Well I need a mail order supplier to CANADA thus that rules out ALTERA.
I may even NOT use Xlinix CPLD's because I like the idea that with TTL I
don't need any programing DONE. The price of PCB's and low cost TTL is
about
the same as using higher cost chips. I might use 2901's from B.G.Micro
as they
are cheap ($1.50) but does anybody know of the original data sheets of
the web
in pdf form?
