All;
I have completed layout of the PCB based on the new schematics
uploaded to the files area. There are relatively few changes between
the previous version and the final version. The biggest change is
that the serial lines to the PIC for flash programming now share a
MAX 232 buffer with one of the serial ports via jumpers.
A PDF version of the Gerber files is in "Interface_Gerbers.PDF."
About 50% of the board was hand routed with the remainder
autorouted. As a result some of the routing may look a little
strange - autorouters are notorious for doing strange and stupd
things. In addition, the Protel autorouter will willy-nilly rip up
hand routed traces or route them again (redundant traces) or mess
with the power plane connections even if you lock traces. I have
done a first pass to find this stuff but there may be more so
consider these Gerbers to be preliminary. Again, any comments or
help looking at them would be helpful.
I will wait a bit (about two weeks) for comments or suggestions
before I send the Gerbers out for fab. After that, it's stuffing the
first protos (oh, joy) and releasing the magic smoke. I plan to only
order 5 of these boards for starters because I am sure something will
be changing and I can't see much sense in having a bunch of obsolete
PCBs laying around.
I know this has taken longer than expected, but I've been feeling
rather punk lately and so haven't been working on this as much as I
should. I hope to have at least one board assembled by the end of
October.

How do you see possibility of connecting YABUS modules?

Jerek;
I've been giving that a lot of thought and will include a YABUS connector for the interface board. I've been monitoring your emails and you seem to have several interesting peripherals available.
BTW - where are you getting your AY chips? I haven't found a source (although I haven't looked too hard either).

Sorry about being unresponsive -- I've been otherwise occupied for
the past few weeks. I will have time this weekend and would like
to comment before too much magic smoke is consumed :-)

Alvin;
I very much understand. I have been slow on this project because
of various other priorities lately. Thanks
