Title: possible to build an adapter for using g4 serial port in a g3?
Post by: supernova777 on September 25, 2014, 01:36:56 PM: here i have taken a photo of the difference in size of the serial modem connector on the g3
vs the one on the g4 agp

(http://macos9lives.com/smforum/index.php?action=dlattach;topic=1841.0;attach=1042;image)

the larger one is a ribbon from the modem connector on my b&W g3 450mhz

the other is the modem from the quicksilver 867mhz , disconnected and overturned to show it next to the actual connector

note the difference in length

are these standards of some sort?
is there a way to bridge one to the other?

i have heard from someone at some point who told me they somehow modified a g4 stealth port to work in a g3.. or the otehr way around
and that it did work

heres another shot of the g3 powermac modem connectors in better res

and the power mac g4s with significantly less 'pins' or perhaps they 'folded it in half' somehow
it appears to be half the size

Post by: supernova777 on September 25, 2014, 05:55:49 PM: my thinking was this:

/maybe it would be possible to "harvest" the g4 connector off the g4's modem..
(which is garbage almost anyway)
and some do a modification to connect this to a g3 modem ribbon connector cable (Easily found for 1$)
which can then attach to the g3!!!!!

it would be tedious work tho;(

close up shot of the modem port on the g3 B&W
seems to be 35 pins.. x 2 = 70pins?

Post by: chokobo on May 27, 2015, 05:08:37 AM: You know I could have sworn that I had my Opcode midi boxes talking to the G4, but I guess it must have been on the G3. I'm going to have to let this one percolate in the gray cells for a while. hmm...

Post by: supernova777 on May 27, 2015, 09:10:26 AM: yes the modem ports are of different size but i think they have the same number of connections .. its just that in the g4 they changed the connector (literally bending tghe same connection in half-length and doubling it over..

i have spoken tosomeone who said they didd this but it was very painful work and took thenm like 2 days to wire it up by hand!!!! and it workd! but forget doing that...
some people are nuts;)
