Very happy now with TFF on my Powerbook G4. Makes it actually practical to use for browsing! Rick

re AM interference - Yesterday I was booting up my IIsi with a SVGA LCD monitor. Another PC nearby was attached to an external audio amplifier. During the IIsi boot period, I was getting a clear signal from a local AM station showing up on the PC-attached audio. When the IIsi display...

Curious that Jobs (famously litigious and security-minded) and Apple Inc (more lawyers than the whole of DC) would somehow allow potentially valuable and/or damaging items and documents to be tossed in a dumpster for a passing high-school kid to find. Well I guess Indiana Jones pulled off...

Hmmm - yes, dumb as in "non-standard". The general SMB standard is that the server offering the share determines whether a password is required or not. Seems Tiger, uniquely, doesn't recognize a null password. I wonder if that was certain developers being hyper-cautious about security, or just...

Not sure if this is the right forum area, but.... I have 10.4.11 set up on a Powerbook G4 and am connecting to a mixed SMB network (Windows, Linux, Mac...) The Powerbook shows up in network directories on other computers and can be accessed by others. However, the SMB workgroup does not show...

Well I did desolder the Bourns filter behind the floppy connector, but it hasn't solved the problem. In fact it seems to have added another problem, because the disk no longer spins up. On power-up, the drive does its self-alignment by seeking Track 0. The floppy request icon comes up, but with...

Fantastic rarity! If it is going to discolor, it will probably be susceptible to ultraviolet light, so this might be worth keeping in mind when you place it for display - maybe not too close to windows or fluorescent tubes. Rick

This ol' thing has 10.3.9 loaded. It has 768Mb RAM. Is it worth upgrading OS X to 10.4.11? One side issue is the browser. I downloaded the current TenFourFox but it won't run - is 10.3.9 the problem? Rick

I'll try it, but I'll desolder the chip in case I can find or make a replacement later. Thanks. Rick

Yes, I think we may be seeing a situation where an electrolytic is more tolerant than a tantalum. Still waiting for any report of this reversed electrolytic actually failing in normal use. If there are cases of it failing before the others on the positive rails, we could infer that it had been...

Exactly this worked for me just yesterday on a Powerbook G4 15". If the PRAM battery is flat, the PMU will not allow booting or charging of the main battery. With the main battery out, leave on charger for about an hour. The power adapter input should go to green. Check the thing will boot...

I accidentally acquired a Powerbook G4 today and found what many threads here have led to - if the PRAM battery is flat, the main battery will not charge either, and the thing appears to be dead. Simple solution is to leave on charger for an hour or so with the main battery out of the case -...

@Technight read correctly. Sounds promising! 'Scuse my ignorance, but where do I locate the bourns filter you refer to? Is it swappable? I don't yet have the schematics to hand. Rick

I've been thinking about that. This rail serves the RS422 ports, driving the negative half of the TX and RX differential circuits. The positive sides of each signal are correctly filtered. So I'm guessing that the filter isn't essential but is there as standard design practice to protect the...

Thinking about cooling - the Mac stock approach to cooling would be to ensure a good thermal bond to some heat-sinking structural element. In Uni's Quadra, that unit is sitting on a pretty substantial metal case element. Maybe as well as his beloved "goop" the drive could sit on some of that...

If the problem is mechanical, I will be relieved - so I'll putz around with the head pressure for a while and see if I get a resolution. Remember this drive reads and writes to one logic board, but not to two others. I suppose its possible the MacII series SWIM chips run to a slightly more...

I have an 800k Sony drive that has stopped booting on a 512k or a Plus, but still reads\writes OK when attached to my IIsi. The IIsi has SWIM chip, the Compacts have the IWM chip. But I understand that the SWIM is just a combination of the IWM with another set of logic to drive the 1.4mb...

Animal pee: Cats don't usually urinate on top of things - they like to do it on the ground or floor. A visiting Tom cat might spray on the side of a box - and that is pretty pungent. Urine on the top of a box is more likely dribbled down from a nest of rats or maybe a possum if they are in...

That looks like an interesting catch, but surprising that failures have not been noticed over all these years. It could be a problem of semiotics. The + sign seems to identify polarity correctly in relation to common GND, but incorrectly in relation to potential across the specific capacitor...

Just a query for consideration - if this is on a negative voltage rail, then would it not be correct to have the positive side of the cap connected to ground? The potential on a negative rail is supposed to be inverted, isn't it? Rick
