Hello again all,
This is really a repost of the thread "Adding Serial I/O on a vintage Z80
system", but thought being specific in the title might get me an answer. I
didn't realize that finding a schematic with parts for a serial port would
be so problematic.
What I need:
I have an old schematic of a complete serial port using an 8251, but the
only piece missing is the baud rate generator clocks. I have received
general information on how to make one, but I need some actual schematics
and parts list (my electronics training hasn't got to crystals and such
yet).
My baud rate requirement is modest as it will just be driving a terminal on
a 1.78 MHz Z80 type system. 9600 baud would be plenty.
I have posted the schematic that I have for the serial port to
alt.binaries.schematics.electronic, so if you would like to see what I want
to build, just check out that posting. It will be the same title as this
post.
Thank you all for your help,
-Commander Dave
