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?

I got one from the net, very interesting:
http://searle.hostei.com/grant/6809/Simple6809.html
But I wasn't able to make it work, because
- I got a 6809E, and the pinout is different
- I burnt a 256 eprom when it should use a 128
- I got a pair of 6850 which one of them is not functional
- I got a pair of MC6809 (not e) which one of them is not functional
- I tried everything, after correcting my errors, and nothing worked
I gave up on this, probably is my fault, but I'll build everything AGAIN
with new parts and try to use it. I'm curious to see it working :o)
(I just love SBC computers :oD)

The Blinkenlight board has an 6809, EPROM, RAM, PIA and ACIA.
An additional (small) board gives you 64 input and 64 output (all TTL),
but you loose the PIA interface in that case.
Have a look at my website (www.pdp-11.nl [My projects]).
I do NOT have the boards nor a kit, but ask Vince!

I haven't seen blinkenlight board in your links :oO...Ah, the Home Made
PDP-11? :oD I'll give it a try..would you have a spare core/io boards? :)

Man, I LOVE this call sign :oD

Nope Alexandre, I do not have those boards. Ask (pdp8 specialist) Vince.
I think he still has some bare Core and I/O boards, and maybe also some
of the major parts (like CPU, ACI and PIA). You can download a PDF from
my website which describes the (simple) hardware.
I could choose my call when I passed the morse code exam. It was the
last morse code exam taken by the government. But since then, I moved
away from PDP8 stuff, because I simply can not afford nor have the space
to start another line of machines. Having pretty much all QBUS and
UNIBUS PDP-11's and several peripherals eats a lot of space!

I do indeed have several sets of boards and parts. (Last I remember was
ordering the parts to populate the remaining boards.) I'll have to look up
what we were charging for them.
