ok, me respondo yo mismo. He tenido una respuesta en un foro de yahoo dedicado a powerbook, así que la publico aqui por si alguien tiene el mismo problema.
To make a resume (if anyone else have the same problem, or would improve
this document), how to connect a powerbook 1400cs (i suppose it could
function to any 1xxx 2xxxx or 3xxxx series) within ethernet card (RJ-45
The first to check is the powerbook 1400cs has (or hasn't) the AUI port, and
has (or hasn't) a PCMCIA Ethernet card or a built-in ethernet card. If there
isn't any card, then there are two possibility:
[a]. buy one of them (PCMCIA or internal card) and install it.
[b]. conect the powerbook via serial (localtalk/appletalk) to a proxy server
(a computer with a proxy server installed and with internet connection; in
my case, powermac 7300 G3 300 with 300+RAM and 2Gb HD), that means a router
machine and, suppose, mac machine.
Whe have a discussion to how to access to internet via (in my case
DSL(ADSL), but it can be modem via) through another computer.
b.1. With Mac OS 9.x (or from MacOS 7.5.3 and Open Transport 1.1.1,
Macintosh PowerPC or 68030 or higher) installed in the server:
Jeanine Cowen have the soft utility called IPNetRouter
(www.sustworks.com/site/prod_ipr_overview.html) and it works ok to
share a modem connection (suppose ok to DSL connection)
I have find another utility web for internet mac utilities:
b.2. Install Mac OS X on the server machine.
Kevin Faulhaber suggest me for it, because X has the necessary soft
build-in. An initial problem is the kind of machine, because i have a PM
7300 with 300+RAM and upgraded CarrierZIF G3 300, but is a unsupported-mac
for X. Remember I tryed with the beta X and it doesn't work. There the
utility of XPostFacto (eshop.macsales.com/OSXCenter/) to install X on
unssuported macs, suppose i try in the future.
b.3. Modification of b.2. Try to install MKlinux, that supposed to have the
same build-in soft to do a 7300 machine a router.
Thanks for Kevin Faulhaber, Jeanine Cowen and Em to the informations. When I
receive the powerbook 1400cs -...usps ground shipping from usa to spain, a
week waiting and they said 2 or 3 more....ufff...-, i will try (if i could)
every option. Then i will report it. I think it could be useful for most
***if someone would improve this, only have to do it***
