File sharing+Printer sharing+MIDI

I have a 6300 (System 7.6.1, internal modem), LCIII (System 7.1), LaserWriter Select 310 and a Roland D5 Synthesizer.  What I would like to do is to share files and my printer between the 2 Macs. Also at the same time, if possible, have a MIDI connection between the 6300 and the Synthesizer.  (And if I buy another printer down the road, probably a
color inkjet, can this also be added in?)

It depends on whether the internal modem takes up a serial port which im assuming does. if it does you only have one port available for both a connection to the other mac and a connection for midi. A workaround that will cost you some bux: Set up a network with ethernet. ethernet doesnt take up a serial port. connect the two macs with ethernet. connect the synth to the available port on the 6300. then get appletalk/ethernet bridge and put it on your remote mac. then connect the printer to the remote mac via localtalk. that will let both computers see the printer (appletalk version of the driver) AND let your 6300 have an available port for midi. that will cost you some bux of course. Other than that youre stuck with only one available serial port for both midi and localtalk/appletalk. I have almost the exact same setup as described above except im using two modems instead of one midi and one modem. now the second senario is that if by chance that modem isnt taking up a serial port (which i doubt). You simply substitute the ethernet with serial cable or localtalk phonenet cable and dont bother with the ethernet bridge. hope that answers your questions.

The internal modem takes up a serial port leaving me just one port, as you say.  However setting up an ethernet network will, I think, take up a serial port (Apple got cheap on the 6300 - no ethernet support).  It seems I would have to use the comm slot for the ethernet card (?).   If so, then how to I maintain my modem connection?

Also, according to the Apple Tech Info Lib article #11517 LaserWriter Select 310: Connectivity (2/93),  "The LaserWriter (LaserWriter Select 310) contains two communications ports:
* A serial port for Macintosh connectivity
* A Centronics parallel port for connection to MS/DOS and Windows computers
The printer has no LocalTalk port, and there is no support for AppleTalk."

Crappy hardware for networking, eh?  Any other ideas?  Or any partial solutions if I can't do it all?
hmmm.....Yes you're right about the ethernet taking up the comm slot. I had forgotten about that in the performas. So your choice is either to ditch the modem in favor of the network or ditch the whole thing. Probably not the answers you were looking for eh? Heres another option but were talkin more $ again. Put a modem on the LCIII with a gateway on it..That way your performa will be able to access the modem thru the ethernet network and enable you to have 2 serial ports open on your performa for the printer and the MIDI. You can share files over the ethernet as well as have both computers access the modem. The printer can be bridged into either computer and the midi can go on your performa. Of course youre talkin some bucks. New modem, ethernet, ethernet bridge. Almost not worth the money. You COULD always just connect things when ya need em but that becomes a hassle. Other than that youre stuck.

Oh yeah forgot to add that ethernet doesnt take up a serial goes where your modem goes in case that wasnt clear.

You're right, an ethernet solution is not worth it.  Would a software controlled serial port switch do the job?  I found a product called "MultiPort" at, manufactured by Silicon Valley Bus Company.  What do you think?
Yeah that will do it. Just checked their page. Looks pretty cool. Now i want one..;) Its probably not cheap but it will do the job and leave you with a few ports left over to play with. If its too expensive a regular old data switch will cover ya.
