Re: N8VEM 6809 host processor running CUBIX

Yes indeed - I do have a couple of CUBIX systems running :-)
I don't think there's much of a user base now, but I have been
contacted by a few people fairly recently who have built up systems.
CUBIX is a small and fairly portable OS for the 6809 that I designed
back in the 80's - It used to be a DDS product, but now is available

BTW, who else is running CUBIX on their m6809 CPU? I'll take Dave as
a given.
Thanks and have a nice day!

N8VEM 6809 host processor running CUBIX

Hi All! I just wanted to share that one of the N8VEM builders has
CUBIX running on the N8VEM 6809 host processor. It is pretty neat to
see and dramatically improves the usability of the system.
I am still working on the IO mezzanine board and it is finishing in
the trace router. I don't know when it will finally complete as the

Hi! I am working on the 6809 host processor and developing an IO
mezzanine board. The IO mezzanine board has a 6551 ACIA, a 6840 PTM,
and two 6522 VIAs. In addition, it includes a bus interface for
future expansion.
I would like some advice on the external bus design. If there are
some experienced 6809 designers who would review my design and

Wanted manual, doc or schémas

M6809 Debug II module
these charts were installed in other apparatuses and which would carry an
other name?.
ces cartes ont-elles été installées dans d' autres appareils et qui
porteraient une autres appellation ?.

Hi! Thanks! Are the schematics for the 6809 EXORcisor boards
available?
That Motorola All-In-One 6809 SBC sounds pretty nice!
You can say that again! Yes, the 6840 specifies separate read and
write instructions for access. That's OK since the program I am
working with (ASSIST09) also assumes this restriction.

The ASSIST09 did not have much to do with the Exorset or the
Exorsiser.
I had it runnning on my first 6809 board in the early 80-s for a short
while, before I wrote an Exbug/disk ROM equivalent so MDOS09 would
boot
(MDOS09 on the Exorsiser, XDOS - pretty much the same thing - on the
Exorset).
I know a guy who made a clone of the Exorset back then (!) - but I am

Hi James! I am building an IO mezzanine for the N8VEM 6809 host
processor board. It will contain an ACIA, PTM, and two VIAs. The
hardware prototype is working on my bench. One of my goals for the
system is to fully support the ASSIST09 debug monitor. Motorola
released the 6809 programming manual with the ASSIST09 source code.

Hi! Does anyone have access to the Motorola EXORset schematics? If
so, would you be willing to either make a scan or look something up
for me?

The UK ebay seller has "more than 10" at $32 each shipped.
If there are enough interested, perhaps a group buy would come
in cheaper? It the price came down a bit, I'd take a few.

The HD6303 is Hitachi's CMOS clone of the MC6801/3. The MC6803 is the
romless version of the MC6801. Both are the progenetor of the
MC68HC11. The MC6801 and the Hitachi 6301/3 use a MC6800 core
instruction set. Hitachi did add instructions like they did with the
