Re: AppleTalk to Ethernet bridge software for Mac?
David,
Thanks for that full on explanation.
I found out that installing the Apple LocalTalk Bridge software was trying
to use the printer port but that AppleTalk was still on the modem port. That
must be the default and I couldn't see how to change it anywhere. This is
why I lost my printer from the printer port and AppleTalk stopped working on
the modem port. Anyway I disabled it and reconfigured AppleTalk to use the
printer port, and the printer on the modem port, swapped the cables over and
now both are working. I assume LocalTalk Bridge is OK now, but I don't think
I have anything that I can test it with, until I get some kind of Appleshare
software on the PC like PCMACLAN or DAVE ?
Just to put you in the picture this is my setup, not as good as Bart's but
I'm new at networking :)
ASCII art begin...
abbreviations:
=== 10Base2
--- AppleTalk
~~~ Parallel
... Serial
(P) printer port
(M) modem port
(S) serial port
(E) ethernet port
(AT) AppleTalk
PC2 PC1 Quadra ClassicII IIGS IWII(AT)
etc===(E)========(E)===========(E)(P)--------(M)--------(M)--------(P)---etc
(P)~~~Epson...(M) (P)...14.4 Modem
33.6 Modem...(S)
What I can do now...
1. PC1 can connect to internet through modem directly on serial port & print
to Epson directly on parallel port & use PC2 shared devices.
2. PC2 can connect to internet via PC1 IP sharing program & use PC1 shared
devices like Epson printer or HDD vols.
3. Quadra can connect to internet via PC1 IP sharing program on PC1 & print
to Epson directly on modem port. Also can print to AppleTalk IWII & use
ClassicII shared vols.
4. Classic II can print to AppleTalk IWII & use Quadra shared vols.
5. Apple IIGS can print to AppleTalk IWII & use Quadra and ClassicII shared
vols.
What I would like to do...
1. Use the Epson printer from the ClassicII or IIGS on the AppleTalk side.
The Epson is not AppleTalk compatable, I can't use it via the modem port on
the Quadra, so can I use it via the LocalTalk Bridge and the PC1's printer
port (sneaky hey ?)
The Epson is a Postscript printer, but I don't think it supports the
AppleTalk PAP protocol you mentioned. Is this what the AppleTalked IWII
uses. If so the the Epson can't do it.
2. Connect to the internet from the Classic II or IIGS via PC1's IP sharing
program.
3. Access the PC shared vols from the Quadra, Classic II or IIGS.
4. Access the Quadra or Classic II vols from PC1 or PC2 via the LocalTalk
Bridge.
5. Print on the IWII from the PC1 or PC2 via the LoalTalk Bridge on the
Quadra.
6. lotsa other things, but that'll do to start :)
I don't have the Quadra configured to use the ethernet for AppleTalk, I have
it set to use the printer port. Otherwise, wouldn't that stop my AppleTalk
stuff from working on the AppleTalk side ?
That PCMacLan sounds like the G O to get some of this working.
