Great! Thanks, Ben.
Had not found this one. "coco" is a good term to include in
the search :-) Will continue looking, but if no cheaper source
turns up, I think I will spend the $31 out of curiousity to see
the actual performance it claims.
The page says that the 63C09 runs cooler than the 6809.
I can confirm that the 68B09 at 1 MHz is warm, but I heard from
Vince that the 6809 at 1 MHz gets quite warm!
tnx,
- Henk.

I am looking for a 63C09E or 63B09E. Anybody
knows where I
can buy it??
I found a source in Australia, but that is the
63B09. The
suffix "E"
is important, it is the *external* clock version,
as used
in the Core
Board of the Blinkenlight project (40 pin DIL
case).
I have a PDP-8/e simulation running on th Core board, but could use
a performance increase. Upgrading to the Motorola "B" parts
will allow
to double the clock frequency, but the Hitachi
63B09 is even faster,
as it does many 6809 instructions in less cycles.
Interested in the sim? Check my 'Homebrew PDP-11' page,
the link there
is "spin off" ...
You really don't want to know the price!

Oh Sorry. :-) Here is the link.

The price is about $32 US each.
- Henk,
PS. If you ever get a good single board 63C09 computer design
thats runs OS/9 level two let me know. I have always wanted a
real computer and the COCO never quite made it.
