Stock/default information: this post doesn't take efforts to make OS 9 bootable on other hardware into account.
date-wise, the 2003 revision of the Mirrored Drive Door Power Macintosh G4 (usually called MDD) is the last.
You got me, Cory! I'm so used to typing QS'02 I got the year wrong for the
MDD 2003 release when I posted that in a hurry before work. My three G4s are '01, '02 and '03.
.
When someone asks about a Mac, iMacs, iBooks and PowerBooks don't come to mind for me, so your added info on those is great to see. I've got a lot of experience with the DA and QS, but haven't set up the MDD 2003/OS9 quite yet. It's the backup machine for the Dual 1GHz Quicksilver I'm using now that was the backup machine for the DA/466. It's really nice when your backup machine can be a significant upgrade over the daily driver. :grin:
My take: though I'm in love with that Graphite Beauty, I'd pass on the DA. If you're looking for the last OS9 machine you probably want the best/fastest platform available. I did a three column comparison of my G4 Macs on everymac at work tonight. Out the starting gate the QS is ahead of the MDD because while its CPU has the same 64k of L1 cache, QS adds 256k "on chip" L2 and another 2MB of L3 (one per processor? dunno, the dual processor thing means next to nothing under OS9) running at full CPU clock. The MDD has 1 MB of backside L2 cache on a 233 MHz bus. (that's my DA/466, didn't check the others, they're probably on a bus that's half the CPU clock as well) You get those benefits without worrying over upgrades, they're bone stock on the Quicksilver
133MHz System Bus, PC133 SDRAM and Ultra ATA/66 are a wash between QS and DA, but for those the MDD gets very interesting.
MDD 2003:
1.25GHz CPU of MDD 2003 vs the 1GHz CPU(s?) top end of the stock QS is very sweet.
System Bus bumps from the 133MHz of both above to 166MHz
RAM bumps to PC2700 DDR SDRAM running on that faster system bus.
Disk Controller bumps to UltraATA/100
RAM hits the same 1.5GB ceiling of both DA and QS under OS9, but 2GB can be installed and is supported when running under OSX.
L3 Cache drops to 1MB on the MDD 2003, but it's running at 1.25GHz where the QS' 2GB runs at 1GHz (still not sure if the extra 1MB is dedicated to the (invisible to OS9) second CPU, so L3
size might be a wash)
The DA case is hands down the winner though. All the buttons and holes are there on the front bezel where they belong for doing anything that might need to be done. Stuff began disappearing from the fancier front panels as the designs "progressed" that should not have been sacrificed on the altar of fashion over function.
That's about as clear as I can put it, I don't mess with CPU upgrades for my OS9 Graphics Workstations, so I can't help there. If anyone wants to hot rod the G4 under OS9, check out
macos9lives, that gang is crazy. :approve:
Cory, thanks for that info about MDD fan speed control under OS9. Anybody got linkage to that info?
edit: forgot to mention the Universal Installer for 9.2.2 the MacOS9Lives gang put together with updated drivers and whatnot. You need to sign up to download it or anything else and maybe even to learn that the installer's there.
