gEDA-user: My first design and multipart symbols

[msokolov@xxxxxxxxxxxxxxx (Michael Sokolov)]

Hello fellow gEDA users,

I'm about to embark on my first gEDA project, which is also my first
hardware design project in general.  (I've played with hardware, hacked
it, stuck my nose where I shouldn't have, etc., but this is my first
time actually designing my own board.)  I won't get into details because
I really need to start drawing schematics, not write more essays, but
it's related to this project:

http://ifctfvax.Harhan.ORG/OpenSDSL/

I'm announcing my embarkment on this project here so that people can
wish me luck, etc., but also to list what gEDA symbols I will need to
create, so that if anyone else happens to need the same symbols, effort
duplication can be avoided.  I will need (and create unless they
miraculously turn out to exist already) symbols for the following:

* MC68302 microprocessor
* RS8973 HDSL/SDSL transceiver
* 29x040 style flash chips
* some RAM
* Altera EPF10K30 FPGA
* PCB-mount connectors: DB25, 6- and 8-position modular jacks
* Lots of other little components I can't think of until I actually get
  to drawing that part of the schematic.

I have a question about proper convention for multipart symbols.  I want
to make the MC68302 symbol multipart, i.e., have several symbols
covering different interfaces of this big chip, all corresponding to the
same physical component.  (This is the standard practice for
representing mega-big SOCs on schematics.)  From what I've been able to
glean from gEDA documentation, one would achieve this effect by drawing
several essentially independent symbols and assigning the same refdes
when putting them on the schematic.  But what naming convention should I
use for this family of symbols, i.e., how should I name the *.sym files?

Expect more questions/comments/observations to follow as I work on my
life's first board design. :-)

MS
