Jury/jerry rigging.

2013-02-15 Thread Dan Stobbs
Here's the Wikipaedia definition of both
terms.   Jury rigging refers to makeshift
repairs or temporary contrivances, made with only the tools and materials
that happen to be on hand. Originally a nautical term, on sailing ships a
jury rig is a replacement mast and yards improvised in case of damage or
loss of the original mast. When more permanence is meant by the term, such
a build may be referred to as jerry rigged.

  I don't like this new Google groups interface BTW!   Dan

Firewire 400 not working in G5 PowerMac

2011-08-19 Thread Dan Stobbs
Greetings all :+)

I've just acquired my first G5: a 1.8GHz with 1GB of memory.  It came with
10.4 installed on an 80GB drive, and I put in a 500GB drive, and installed
10.5 on to it (my first SATA experience - went very smoothly) via Firewire
800 from one of my MirrorDoors, which came with a Time machine drive with
Leopard on it.
Both OS'es are fully updated.

Lovely machine apart from a bent back leg, so it has had a fall in its
history (probably why only two of us bid on it, and I got it for a
reasonable price!)
Gorgeous design statement although not as upgradeable, hardware-wise as the
MirrorDoors. But I digress.

All went well, but when I tried running my Firewire speakers, they lit up
but when I looked at System profiler, it showed only the Firewire 800 bus as
being present.
I tried resetting PRAM and then NVRAM with no change.

But wait,  I have Firewire cards,  I thought. The first one wouldn't fit:
seems I now have a Mac with PCI-x slots!  However I had a brand new 800/400
card that went in nicely, and now when I look in System Profiler I have two
firewire 800 channels listed, but still no Firewire 400!

My firmware seems to be up to date.

On the positive side, I now have 2 more FW800 ports, and I can connect my
external DVD drives via 400/800 adapter leads.

Is the FW400 on the motherboard FUBAR'ed and would this mean it would not
recognise the FW400 'bits' of the card?
 From memory,  disk utility knew my 1st gen iPod was connected, even though
it wasn't showing on the desktop, .

Hoping y'all can cast a little inSight on this
Dan.

1.25 eMac running in safe mode.

2010-03-03 Thread Dan Stobbs
I recently bought one of these with the failing caps problem.

described thusly

 ... as spares and repairs because I dont have the time to reinstall Mac
OSX
 boots up to statup then sits on mac loading screen may just need
reinstalling .
[image: 
Photobucket]http://i459.photobucket.com/albums/qq312/rubblemania/1-1-2-9.jpgthis
was how it arrived (seller's photo).


basically for spares for my other eMacs and because I like a challenge,
and it *may just* have needed a re-install (another one I bought for spares
came without a System folder that had been trashed somehow so nice kernel
panic when I turned it on - an OSX install sorted that one although since it
is clogged with sawdust I need to strip and clean it before I dare use it
for anything!)

While I can wield a soldering iron I'm not intending to repair it but I've
been playing with it as a result of email conversations with an ebayer who
had one up for sale.  She said that hers will surf in safe mode, so I dug
mine out with a view to trying this out.
When I turned it on I found that I was in the middle of re-installing OSX on
it when I got fed up some weeks ago.
I started it in Safe Mode and was able to complete the installation
satisfactorily, then started it in Target Disc Mode and moved a few files
across, including the combined update.
So now I have an eMac running 10.4.11, and in safe mode it seems quite
happy.  Trying to boot it normally, it sometimes freezes at 'Starting OSX',
sometimes gets as far as  a desktop, but then the mouse freezes - basically,
as expected, no functionality.
So a couple of questions.

I usually share my internet connection between my Macs using a firewire
cable (why - because it just works beautifully!)
In safe mode I do not seem to be able to invoke this functionality - system
prefs only shows ethernet as an option. Am I missing something obvious or
can I only do this in full bells and whistles mode?

Everything *seems* to work fine in Safe Mode - I've installed a couple of
small apps  - Onyx, Neo Office, my printer - and they seem to work OK. (not
actually tried printing yet though!)
 VLC 0.9.9a doesn't seem to output video and sound - having just checked
System Prefs, it shows no input or output devices found, so do I lose sound
and video options in safe mode?
The eMac seems stable enough in Safe Mode, no video artifacts, random
freezes, mouse hanging - what kind of voodoo is going on here - I would have
thought that dodgy caps would cause problems in safe mode as well?

Looking forward to the group's erudition on this1

Dan.

Yes.


 Does it pass AHT?
 Didn't occur to me to try that - good one  -I've got several AHT disks in a
 box somewhere - almost certainly got a couple of eMac ones as I have 6 or
 seven eMacs (don't ask! -  two of them were bought spares/repair so I could
 learn how to take them apart - one has defective IVAD cable - planning to
 use cable from the totally dead one to fix that when I get space on bench

 Safe Mode is a restricted/limited environment.  Many drivers are not
 loaded.  Many services are not running.  It is meant as a debug/repair type
 mode, not for regular use.

 Running as you suggest is the equivalent of driving your car on the rims,
 with the top down, in a thunderstorm.  It will get you home, in a pinch, but
 you will get wet and perhaps fried on the way.
 Fair comment, although IMHO it seems a lot more functional than I remember
 'Safe Mode' in Windoze being. Obviously (?) sound and video drivers not
 being loaded - no VLC functionality but Neo Office seems to work OK. My
 correspondent is using hers to surf and apparently findin it satisfactory
 although without UTube functionality. .

  *So now I have an eMac running 10.4.11, and in safe mode it seems quite

 Look in the system log to see what's failing.

 OK. System log looked at and saved. But that system log is from Safe boot.
So I thought I'd reboot, allowing normal boot until it hung, and then
restart in TDM so I could access log via my G4 lampshade. Did this and I
found references to my Wacom Bamboo tablet, which I've recently installed on
the G4!  So I disconnected FW lead and rebooted the eMac. It got as far as
the desktop this time and I moved the mouse onto the Apple menu which
opened, and then froze with a spinning pinball.Turned off eMac, restarted in
TDM and then connected FW lead and went drilling for logs in
1.25eMac/users/myfolder/library/logs. This got me to disk utility log.
Clicking further got me to system log which I attempted to copy to the
clipboard for study in textedit - I got nearly to the bottom and then it
vanished.  Before I try again am I looking in the right place?


 Try booting in Verbose Mode, to see how far the boot process is getting.
 Tried that already before I posted. Unfortunately it doesn't stay on screen
 long enough to read it before it goes to colour screen!. Is there a way of
 pausing the boot process to allow me to read it?

Heavy duty, feels-good keyboard for typist with a vengeance

2010-02-25 Thread Dan Stobbs
I can certainly recommend Lindy USB Mac specific keyboards.  They use
switches rather than a membrane, so they're very positive action (although
not the quietest in the world!) and also have two USB sockets so rodents can
be plugged in.  Don't know if they still make them to this standard: I've
bought all 4 of mine off ebay and they date back to G3 days, and come in
various Mac colours. They work well, and are relatively easy to dismantle
for cleaning purposes.  They have a similar  feel to the classic IBM AT
keyboards that everyone used to love in XT/ 286 days!

Regards, Dan.
