[Coco] Motorola Parts Missing in ExpressPCB

Picking up on that topic (PCB vendors and stuff), can I ask the list some
quick questions?

I have been playing around with the idea of designing HW stuff as hobby for
quite some time now.  It's been ages since I left the HW arena for the SW,
but I do miss the thrill of building new stuff from scratch, specially if I
can attach them to our beloved CoCo...

I still have an original design of a logic tester for the CoCo I built in
the 1980's... The "inteligence" was SW (an IC database and their testing
routines), but packing together flip-flops and buffers to transmit and
collect info from the IC being tested was fun...!

That said, can the list point in the right track again?

1) I use a Mac as computing platform.  Which software would you recommend
for circuit design?  Linux is also available to me, but I dropped the
"Windows habit" many years ago! ;)
2) Do these PCB vendors take up a circuit schematic and work out PCB layout
and the works or do you have to do the layout yourself?  If the latter,
which routing software (if any) do you guys use/recommend?

Thanks a lot!
Paulo.
