Hi
From the N8VEM home brew computing project wiki front page:
The three 6809 standalone computer boards available in the
Eurocard (160 x 100 mm) format; the 6809/6802/6502 host
processor, its 6809/6802/6502 IO?mezzanine, and the
6809/6802/6502 bus bridge.? A redesign of the 6809 host
processor board has been completed and the new version
supports 6502 and 6802 CPUs in addition to the 6809.?
?
All Eurocard ECB?format PCBs are $20 plus shipping which is
$2 per board in the US and typically $5 per board overseas.
?

?
There are PCBs for the 6x0x host processor and associated
boards still available.? There was quite a bit of active
development on this system a few months ago.
?
Thanks!

But elsewhere it says:-
"The Z80 in the SBC serves IO for the 6809 host processor as it does not
control the ECB directly. However the 6809 host processor can get the
attention of the Z80 CPU through the ECB interrupt system."
which to me implies you need the z80 card..
.. or have I missed something

Well we have had all the fun with 68K
designs, but I would really like
to build a 6809 system. Any one know of a source for boards
for a
simple system with say Serial Port and Parallel Port and
memory?
