Bah.  When I wrote Initio in my original message, I meant Atto.   Leaky 
brain.

The Atto cards are great, from what I've read, but ones like the UL3D and 
UL4D are dual ported cards.  I had a UL2D and it had to be installed in a 
non-Bridge slot in the Umax S900 in order to work.  

They will work fine in one of your MDD's slots, but *might* have problems 
if you get an expansion chassis.   As I wrote, I don't know if Apple fixed 
that bug after the x500/x600 PCI PowerMacs.

I think that the UL4D does not have support for OS9.  You'll want to check 
that.   So the UL3D may be your best choice amongst the Atto cards.

If you want a single ported card, consider the Adaptec PowerDomain 29160, 
but check if OS support goes late enough for you.  I have this vague 
feeling that Adaptec stopped providing updates at some point.

 Thanks everyone for you help so far. Are there any suggestions for a
 suitable G4 with more PCI slots?

Forgot a couple of questions.   Yes, as far as I know all the SCSI
controllers will drop back to earlier protocols if an older device is
present on the bus.  Some of the newer U320 SCSI drives won't, but
that's probably not an issue for you in this case.

The MDD has the most PCI slots you can get in a G4 PowerMac.  It has
four PCI slots, plus the AGP slot for the graphics card.   It was a
very nice machine in that way.   The only way to get more PCI slots in
one box would be to get a PowerMac 9500 (or 9600, or Daystar Genesis,
or PowerComputing PowerTower Pro) and install a G4 upgrade.   The
9500/9600 has six PCI slots.

However, the 9500/9600 would have a much slower memory bus.  The
fastest G4 upgrade available is 800 MHz (was there a 1 GHz?).  There's
no AGP slot so your effective PCI slots drop to 5, because you spend
one on a graphics card.   There's no USB nor Firewire, so if you need
those, that's another slot and you're back down to the four that the
MDD has.  It does have SCSI built-in, so potentially, that saves you a
slot, but the faster of the two SCSI busses is only Fast SCSI (10 MB/s
theoretical).   The slow built-in SCSI also means that your hard drive
access is slow unless you add a fast SCSI card and drives, or an ATA
or SATA card, which would cost another PCI slot.   Finally the built-
in ethernet is 10 Mbps.

So, unless you could live with all those limitations, I think the MDD
has the most available PCI slots you can get.

Re: G4 MDD SCSI (pref non PCI)

2012-08-29 Thread Oliver Fairhall
The audio output of the samplers is feeding an interface on my main 
studio PC. The MDD is not being used as the audio workstation host, or 
the main sequencer. It's mainly a DSP farm (again feeding my main 
interface on a PC). MDD will also be used to control the samplers more 
detailed functions (easier than the small hardware interfaces), off line 
sample editing, import/export/conversion of other audio into/out of the 
samplers, and some file storage.


I did consider an older G3 just for sampler SCSI interfacing, but my 
home studio is getting too complicated/crowded already. A single legacy 
Mac would be preferable to me. A PCI expansion chassis is a reasonable 
solution for me. I'm already running 4 computers (including the MDD); my 
main PC as DAW, a laptop to edit my Nord modulars + daily computing, a 
legacy PC (rarely used for music, mostly just AXS 
http://www.resolutionaudio.nl/), but is there more for legacy RS-232 
EPROM programming, and for some older music gear that requires true DOS 
environment for the occasional floppy based operation. One sampler also 
has it's own LCD monitor, so five monitors all up. Plus rack hardware, 
desktop controllers, and keyboard synths. Of course, this all comes with 
an ample serving of cable soup.


Cheers,

Oli

Might be a lot easier to manage.

Just thinking about your ‘cable soup’ and the number of monitors you have 
running - hot, easy to trip over and large electricity bill.

Might it be worth running some form of VNC on your macs. (VNC, rebadged as 
‘screen-sharing’ has been part of Mac OS since 10·3, IIRC.) 
- For OS9 macs, there’s ‘OS9vnc Server PPC’. I’m using it to observe and 
control my Pismo from my mac Pro just now. 
- For logging into and attempting to help with my parents’ PCs, I’ve used 
TightVNC and ChickenOfTheVNC, IIRC. (Bit slow over the interweb but OK over 
LAN.)

(Before using screen-sharing so much, I used to use a 4-port KVM switch to swap 
my monitor between Pismo, XServe, main mac and work-provided mac but cables 
took over my desk and shelves, then eventually the KVM unit became flaky.)

I guess VNC might slow your pooters slightly but it might be better than 
tripping over a cable and dragging loads of kit onto the deck with you.

cheers

VLC vs Leopard

2012-08-29 Thread Dan

Hi,

I finally updated my QuickSilver (2002) from Tiger to Leopard, yesterday.

For the most part it went well.  Clean install of 10.5.4 then applied 
the combo to get to 10.5.8.  SU hit me with a bunch of stuff, like a 
Security Update and Java.  But then I had to fetch the latest iTunes 
and QuickTime from Apple manually - they weren't showing up in 
Software Update at all!


Performance seems good, except for VLC...

I've got a bunch of mpeg-2 videos (direct DVD rips and such) that 
played quite well in VLC 0.9.10 on Tiger.  But in VLC 2.0.2 they 
stutter badly, then VLC crashes!  I reverted to 0.9.10, and they're 
playing smoothly again.


Anyone else having problems with VLC 2?  Is there a build between 0.9 
and 2 that's worth trying, or should I just stick with 0.9.10?


Thanks,
- Dan.

I noticed this behavior also.

Think think Software Update has been limited to system software and  
everything else goes thru the AppStore now? The fact that Leopard  
doesn't have an AppStore app doesn't matter too much because Apple  
doesn't support Leopard or PPC any longer.
