Well the thrust of that link has to do with some obscure [or he's wrong because this make little sense to me] issue with a dead HD preventing any booting and the flashing disk.  Th…

Link you've posted to refers to resetting the SMC (system management controller), which is analogous with Intel Macs - kind of like resetting the PRAM/CUDA on pre-Intel Macs.  Not …

I know this is a totally different ROM, and I know nothing about Macbooks so I don't even know if this info is correct, but there's no way, right... ?  https://www.ifixit.com/Answe…

Also the HD spins before the screen powers on.  I get no impression the floppy module does anything - but that may just mean it's not getting to a disk check - which should probabl…

The same cable used on the Mac II to 13 inch color, LC to 12 inch color or b/w is the same cable for the IIgs. Make sure its the thick cable with all 15 pins on the heads. The thin…

Hello guys, I found a very nice IIgs with monitor and drives. I works great, but I can't connect it to the RGB screen as I don't have the proper cable. Does anyone have a spare t…

With or without the PRAM battery, actually, it chimes infrequently and only through the speaker panel; but it comes on most of the time - not always.  It's worth noting that my 530…

Thanks for the response.  I didn't fire it up right away but I didn't let it thoroughly dry per se (I really went at it with the hairdryer - very thoroughly - including opening tha…

raoulduke said: I promptly disassembled it, removed the PRAM battery (which was not dead).  There was a little bit of very confined corrosion but in general the board is in f…

That was a slightly inaccurate description.  It would chime, and I could soft reset, but it would shut down within 5 seconds of chime.  The first time it might have actually restar…

I got the second PB 3400c today.  The battery was still in (both, actually).  When plugged in, it'd make the popping (probably speaker) sound and sometimes the screen's charging-li…

Super! Thanks very much for the power information. I will try to get an ATX power unit.

[Obviously that was partly off-topic but the same holds to the Restore CD.  Does the license with that software pass through the individual buyer or through the machine - can that …

Apparently the editing just expired.  [i actually missed your eBay suggestion - that's also part of my fascination - buying an almost certainly used copy... would that convey the l…

I understand why you'd think that this is piracy.  However, though the copyright office doesn't seem to have anything filed on System 7... (http://cocatalog.loc.gov/cgi-bin/Pwebrec…

Under the forum rules, links to pirated software are disallowed. If you were to search online for the installation media, you may find a way to buy it (on eBay or whatever) or a w…

<snip> On how to remove the PRAM battery - the connector to the power board is under the box/chassis the hard drive is in. The battery is glued under the speaker pan…

any docs on how to do so?

Also remove pram battery fast. Quick! Quick! If it leaks it's toast!!!!

I'd try and get my hands on the PowerBook 3400c 7.6 CD.

Hi. Now that I have started to use my 3400 on a more regular basis, I have been noticing many software problems; probably due to whatever the previous owner had installed/hacked w…

Durr, I totally never uploaded the pinout anywhere. Anyways, yeah. Even in a Lisa 2/5 all the voltage pins you need are present on the power supply. You just need to break them out…

You've actually made me think of a caveat to my 3400 source.  The original PRAM battery has a three-pronged connector, but the replacement suggestion has a 2-pronged connector.  (I…

Hmmm.... to be ugly, you could cut the wire in 1/2 and then splice a longer piece to it. Now, this may not work because the connectors wont probably match but you could try for a …

Related: how would one look for the extension wire (like for the 3400) - either three or preferably two pinned? I don't even know what it'd be called.
