powerbook duo 2300c PowerPC 51 posts Mar 5, 2008 — Dec 16, 2008
hi all,

this is a replica of my post at ppcmla.com, sorry for making such duplicates.

i recently obtained a last series powerbook duo (100 mhz powerpc, 800 mb hd etc.). it has os 8.1 installed and runs decently. what i really like about it is the size, but alas when i looked at its ports it was plain horror.
it only has a modem and an i-don't-know-what port which has a pictogram of a telephone and a printer on it and is called (by the os) modem/printer port.

now i understand that it used to be inserted into a 'duo dock' but i do not know where to get one and even if i could i wouldn't want to only for the sake of ports.

can anybody help me how to get stuff (like a nice 7.6.1 and ram doubler) onto it? it has no floppy, no cd, no nothing..

thanks,

bamdad
This is one of the big problems with the Duo line as a whole (and not just the 2300). While it doesn't have much in the way of ports it does have an ADB socket and a serial socket (the telephone/printer). If you're not willing to get a docking station (the Duo Dock is big but maybe post a want ad for a mini-dock) then you can hook the serial connection up to another Mac and communicate via good old AppleTalk (just need a common or garden Apple serial/printer cable). It'll run dog slow but it'll work (I know as I transferred all 20 disk images for OS 7.5 onto my first Duo using just the serial cable)

ahh.. so i have no other choice. i tried to use the modem but the previous owner did not install the appropriate control panels for it (modem, tcp/ip etc.).

alright, should i then go for the micro dock according to this article, for it has (or may have) ethernet? i'm guessing there are several types of micro docks. it doesn't state anything about the mini dock and ethernet. could you enlighten me a bit?

Take the HD out and stick it in an enclosure...

it won't work. one thing is i have no scsi compatible stuff (and i am more willing to buy something that i can easily network with) and the other is that i tried to take it apart but only managed to remove the keyboard and saw frightening stuff underneath. compared to this my powerbook g4's guts are visually appealing and straightforward. :)

Without the appropriate controls panels then you are kind of stuck.

I've only ever used the micro-docks and can't say that I've come across one that has ethernet (definitely seen them with HDI-20 (floppy) and maybe with HDI-30 (SCSI) and might even have a spare HDI-20 one if I remember correctly - I'll have a check and see if I can dig one out). Unless you have the correct control panels though, getting a micro-dock with ethernet won't do you any good as...no way to install what you need.

EveryMac doesn't list ethernet with the mini-dock but I'm sure that I've seen a pic somewhere that shows what looks like an ethernet socket.

[Edit]Came across a site that mentions that while the official Apple mini-dock didn't have ethernet, docks produced by third party suppliers did come with an ethernet socket[/edit]

thanks a lot, but don't bother looking for an HDI-20 because i have no floppy drive (only an IDE one for my old pc).

ethernet would be the best option since i have loads of classic apps and games, and some don't really like classic and os 9.2.2 on my pbg4. not to mention being able to use almost anybody's internet connection - including my own - would be insanely great.

i am thinking of creating a portable word processing and retro gaming machine to carry around in stead of my pbg4.

and, if i'm not mistaken, chooser and the appletalk control panel are loaded, so i should be able to use ethernet once it's installed. then i can refresh the system and onwards into the winderness.. :) sorry, i got a little carries away there.

hm.. and i'm guessing those are exremely rare..

I'd never even heard of them so I'd have to agree with you ;)

BTW If you have AppleTalk and Chooser installed then you should be able to hook up via the printer/modem socket. Just plug the other end into another Mac, setup an AppleTalk connection and you're away

i have thought of that earlier, but i have no cables (know any haxie to attach an ethernet cable to say.. a PS/2 mouse plug? :D ) and my oldest mac is a quicksilver g4. quite a sorrowful situation..

btw only in theory - since i haven't any modem or ppp control panel - am i right to assume that PPP connection via directly connecting two modems is impossible? (it would make sense if it's called peer to peer protocol but who knows..)

Duo / does have an ADB socket
Bzzt nope. Just a serial port marked modem/printer, and a modem if installed (a panel blank if not). For ADB you need a Minidock or Dock of some kind, or an internal hack which involves soldering.

There are some very good documents on the Powerbook Duo series and their docks online, which a little Google should reveal to you. The word "FAQ" can be helpful.

If you have a Dock with SCSI (ie nearly all of them I think) and a SCSI cable with the "Dock" switch on it, and another Mac with SCSI, you can boot the Duo up in "SCSI Disk mode" ie the drive inside it mounts itself as an external drive on the other machine. Drag, drop, install, format to your heart's content.

Yes, indeed you can connect two modem-equipped computers together this way. All you need is a "phone line simulator." In its simplest form, a battery, capacitor and resistor will do the job. Many versions of this basic circuit can be found on the web. An example is http://www.jagshouse.com/modem.html

In some rare cases, a modem may not function with 9V. I've never had one not work with 18V, however, so in the worst case, two 9V batteries should suffice. If you plan to transfer many bytes this way, a non-battery implementation is probably a better choice, but requires just a bit more labor to construct.

thanks, i'll look into it. as for the SCSI disk mode, i'm going to try it as soon as i get another vintage mac and a scsi cable. anyway, interesting info, i didn't know pre-firewire macs can do this.

for now ethernet would be best.

now this is weird. never though it's so simple. if only the previous owner didn't have deleted such essential control panels maybe i could have used ppp's or remote access's (don't know which one) terminal to issue direct commands to the modem.

until i find some way to get ethernet or to use Bunsen's method i'm stuck hard. and i guess even if i were to buy a serial to ethernet adapter it wouldn't do the job.

It's been too long since I dragged a Duo off the shelf and had a look (and I always have mine hooked up to a microdock so there was always one available). Alas, stuck in an office, I had to rely on my obviously shaky memory :I

Apologies for giving out misleading info. :(

The Floppy MicroDock had an ADB port, as well as the HDI-20 floppy port. Don't know about any of the other MicroDocks though.

wow. you beat me in googling. ::) thanks again, links highly appreciated.

it seems whai i really need is a newer technologies microdock. hope it does not require software to be installed.

btw i just noticed that the system profiler reported a weird thing: internal hd - ATA. this means that it's not SCSI, and if i can figure out how to get it out (it should be documented somewhere) i might be able to put it into my quicksilver and do some installing there. going to try this afternoon.

Yep, the 2300 is the only Duo to have an ATA HDD.

Don't attempt a Duo disassembly and reassembly without a pictorial guide. The ones at ifixit.com are pretty good, but I don't know if they go as far back as the Duos. Someone here might be able to send you the appropriate guide, or at least prompt you with the file name to search for.

Even when you do get it out, you'll need a 2.5" to 3.5" ATA adapter. I reckon you're better off in the long run getting a dock of some kind and a SCSI docking (ie switchable) cable.

don't worry, i won't after have seen what's inside that bastard. maybe only if it's my last chance. :)

still waiting for that dock.. but if it needs third-party software to work then maybe i'll try to trade the whole powerbook for another - my old dream - a 68k one. preferably a 68LC40 one.

hi all,

i recently bought a 5300c with a farallon en card. now the card does everything but work, despite that it has its own working driver install floppy. under 7.5.3 it is shown in the TCP/IP control panel, but on activating it, it just freezes. under 7.6.1 it doesn't even show up although it's on the desktop.

i even downloaded a newer verion of the driver, installed it, but alas, no effect.

so if anybody else has had this problem, please help me out. if there will be no solution, i'll try to trade it in for a pb serial cable to connect the two 'books and finally get some software installed on the duo via the 5300's floppy drive.

thanks and all the best,

bamdad

One problem I have run into with 5300s is that if you use an older PCMCIA card, it might only have 68k 'Classic Networking' drivers that don't work with on PowerPC; and no PowerPC/OT drivers. (I ran into that issue with WaveLAN, until I found the PPC OpenTransport drivers.)

thanks, but these are all fat binaries. ;)

I loved the Duo series. It may look scary to disassemble but it's actually quite easy. Nevertheless, docks are an easy way to go.

As for all the Etherdocks, yes you do need drivers. I haven't looked in a while but the Ethernet Micodock was one of the most prized of all the docks and it was quite expensive and extremely rare. If you do find one, I have a driver for you.

In the interim, you should definitely get a SCSI microdock, which has an HDI-30 SCSI connector and an ADB connector (like all microdocks).

You will also need either a switchable SCSI adapter or a special 30 pin HDI-SCSI to DB-25 SCSI cable and a DB-25 female-to-female coupler as well as a DB-25 to HDI-30 (29-pin) SCSI peripheral cable. I have never put two powerbooks together where one was in SCSI disk mode. It may not be possible if one of the PowerBooks does not supply termination Power and may require a powered terminator as well. Did they even make HDI-30 to HDI-29 pin cables? The whole process is MUCH simpler with a vintage desktop, then you need just the one cable. I brought my PowerBook 100 back to life through SCSI disk mode via my compact Classic. FYI, The very first PowerBook had SCSI disk mode, but not the early 100 series. Most others have it.

In any event you can install software this way but you have to exercise caution as you must tell your installers what kind of Mac to install for. Or use something like "Wish I Were" to fool the installers into thinking the 5300 is the 2300.

The HDI-20 external floppy & microdock is a nice thing to have, but nowhere near as fast as SCSI disk mode.

The 2300 is a fantastic machine. Given its size and power I would definitely try to get it going again. Like anything worth having it takes a little bit of effort to set it up, but once you do it really pays back. I used my 2300 from 1996 to 2000 when I upgraded to a PowerBook G3 Firewire and continued to use it until about 2003 on a regular basis. In my opinion it is the best looking of all the 90s PowerBooks.

you must tell your installers what kind of Mac to install for. Or use something like "Wish I Were" to fool the installers into thinking the 5300 is the 2300.
Or at least with the system software, you can tell it to install a system for any Mac, IIRC

scsi microdock.. got it. :) hope there will be some on ebay. hope somebody will be willing to ship it to this godforsaken country. :p

Try dlchief58 on ebay US. He's got a 16sce dock at the moment, which has SCSI, Ethernet and video out.

This one's got it.
No, that's a 16sc. He did have a 16sce last time I looked. Maybe if you ask him he'll have another.
