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…

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…

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…

I should have put a question mark on superseding. It's a proposal-topic. It just seems like there's next to nothing on 3400 repairs.

I'm hoping this can be a repository for specific repair help/information for the Powerbook 3400c.  Macdrone has been doing sort of research/experimentation on repairing some of his…

I started another thread in the hack section, Since its more of a project than a "Feeler"  now. 

Guys, I have a discrepancy here.  Designing cards and drivers for macintosh, and the original portable developer notes list the slot like this:  but...  Guide to the macintosh…

Technight... we are all chomping at the bit!!! Can't wait!!!

my CPLD development board came in today. Cool little thing. Now just waiting on the JTAG.  better start working on the PCB layout, but I need to come up with a footprint/pin for t…

I'd be in for two also, it sounds like it's coming along well.

I am sure you do Techknight.. I am sure you do!!! Sign me up to purchase your product!!! I know others that will buy too.. And of course I bet a ton of people on here.. Uni prob…

the only way to expand it past 5MB is to use the PDS slot.  Well, I got other ideas.... 

Hey TechKnight… So I've got a Kingston 4MB card for a 5126 and three.. yes that is three weird RAM upgrades that bring my 5120's and 5126's up to 7MB.. I haven't figured out how to…

I have a velcro strap rack designed for shipping TSOPs.  it has 26 I think AM29LV320 FLASH TSOPs in it.  Those TSOPs I cant use, maybe I can ship the carton to you and you can fi…

I didn't have any luck finding them on his page either... I went to an locally owned Ace Hardware here in Boise to get some keys cut for work and found some brown 3M replacements …

I found the designing cards and drivers for macintosh family online.  It appears BOTH the portable and backlit portable GLU will only decode and DTACK 5MB of address space. So for…
