Mac Forum / General / Hardware / September 2007scsi internal drive in g4?
Hello, I've an old powercomputing mac clone which I've been using for close to 10 years (the machine crawls at 180 mhz). I took the machine apart and recovered a 6 gig scsi hd that I plan on installing on a G4 (digital-audio). Can this model (the g4) handle scsi?

I would need one that'd be ok for os 8.6 (yeah, I still use 8.6 -actually the disk shall host 8.6) thru X.2 >>> I've an old powercomputing mac clone which I've been using for close to >>> 10 years (the machine crawls at 180 mhz).

Adaptec cards that are specified as Mac compatible will do. ATTO cards as well but these are expensive.

It worked perfectly until OSX Panther, so I took it out and bought a firewire scanner. I still have the card. If you want it, and if it doesn't cost a lot to send it to France, email me privately with your address, and I'll mail it to you. I might not still have the driver CD that came with it, but that version has been superseded (you can probably find the latest version online somewhere). >> >>> I've an old powercomputing mac clone which I've been using for >> >>> close to 10 years (the machine crawls at 180 mhz).

Magdalena, That was just the card I was thinking about (currently browsing the adapted website), and yeah, that would be very kind of you. Perhaps I could pay for the shipping? Anyway you may reach me at: henri dot baeyens at free dot fr and we'll discuss the matter.

Absoloutly true! but if he wants a card that would be cool for both Wide and narrow Scsi and can boot both. he should look on ebay for a powerdomain (its the Adaptec Mac line) aha-2940UW-mac which can also boot scsi CD/DVD drives as well. If he wants the fastest, meanest card that I know of, he can look for a powerdomain aha2940U2-MAC I am sure one can find those on Ebay relativly cheaply.

Or even the AHA-29160 / 39160, both can be used with blue & white G3 onwards, with OS8.x to 10.4, they support wide and narrow SCSI and are the fastest Mac cards Adaptec produced. They are bootable and very quick if used with 15000 RPM Ultra-160 drives. The only problem is that the Pre-Release versions of 10.5 will not install with one fitted (I think 10.5 has problems with any bootable SCSI card), However I don't think Henri has a machine that will ever run 10.5 so this should not be a problem.

That SCSI drive is very small and very slow by current standards. Your G4 will run much faster when booted from a recent ATA drive. (You can't boot that machine from Mac OS 8.6, by the way.) SCSI is dying at the enterprise level and essentially dead at the consumer level. Don't invest any more in it than you need to. If you can't get the network method to work, find the cheapest SCSI adapter (probably an Adaptec 2906) that will work in your G4, transfer the data from the SCSI drive to one of the G4's ATA drives, delete your personal data from the SCSI drive, then pull it and the adapter card out the G4. If you have no further use for the Power Computing clone, put the SCSI drive back in it and give the thing away. Then sell the adapter card and forget about SCSI. >> so, the 2906 won't let me boot from the scsi drive? mmh... bummer > [quoted text clipped - 4 lines] > drive back in it and give the thing away. Then sell the adapter card and > forget about SCSI. I don't quite agree! First of all I have TWO scsi cards in my B&w. a AHA-2930CU-mac and a AHA-2940UW-MAC. (the 2930 is for my scsi scanner) the 2940UW is for two SCSI Hard drives I had laying around. Thanks to both I can have approximatly 20 hard drives ;) (the 2940UW is a WIDE/Narrow card, thus allowing 14 devices). Having a scsi card in a boxen is good for testing hardware as well. But... yes, if you want current.... Go Firewire for external. I can get loads of SCSI Hds for pennies and I have to save my green stuff. So, if you can get inexpensive SCSI hardware... its not a bad way to go.

Then sell the adapter card and > forget about SCSI. ohh... more bad news! I have old scsi devices, a zip drive, a scanner, the hard drive; the zip drive was first replaced by a usb one which I don't use anymore since usb keys came around; bought a new usb scanner (the old scsi one gathers dust on a shelf). I know scsi's almost dead but the whole point was to be able to reuse the scsi drive (even though I suspect it might be slower than the newer drives but in 1998 it was amongst the fastest drives). I'm in no need of disk space but that appears to be a case of me trying to salvage devices before finally come to the inevitable conclusion that their time is up. I'm a romantic. Anyway... And you say a g4 can't boot os 8.6? Why the hell not? Is it strictly software? or are there hardware incompatibilities? It appears that the only thing I might be able to reuse is the adb keyboard (gotta get an adapter); I never quite liked the new mac kbrds anyway. > And you say a g4 can't boot os 8.6? Why the hell not? Is it strictly > software? or are there hardware incompatibilities? Well, the bottom line reason is that that's the way Apple does it. A new Mac will usually only run the OS version it came with and the new retail versions released over the next four years or so. Apple doesn't do this just to be annoying. Software has to be compatible with the hardware. In particular, bits of software called "drivers" are required to mediate between specific hardware components and the other elements or layers of a specific operating system. With each new OS version, Apple bundles drivers to allow some of their older hardware to be used with it; but they generally don't provide drivers for new hardware to make it compatible with old versions of the OS. This allows for regular improvements in hardware design while keeping the OS installation process simple. For an (admittedly extreme) example of the alternative to Apple's way, see <http://stevenf.com/2007/09/macs_really_do_run_windows_better.php>. Your particular PowerMac G4 (Digital Audio) cannot boot from anything earlier than 9.1. (I _think_ it can boot from a retail 9.1 installer CD in addition to the installer disc that came with it, but I'm not sure.) > It appears that the only thing I might be able to reuse is the adb > keyboard (gotta get an adapter); I never quite liked the new mac kbrds > anyway. You don't have to use an Apple keyboard. There are several other brands of USB keyboards that will work with Macs. > Hello, > I've an old powercomputing mac clone which I've been using [quoted text clipped - 3 lines] > > Thank you I have an Adaptec 2930 in my Quicksilver (G4) and it always worked well until I retired my (still working) SCSI drives. I just can't imagine that the PCI card expense and hassle is worth 6GB, however. >> Hello, >> I've an old powercomputing mac clone which I've been using for close to [quoted text clipped - 7 lines] > until I retired my (still working) SCSI drives. I just can't imagine > that the PCI card expense and hassle is worth 6GB, however. it's small sure, but it remains a good disk (a seagate sheetah 10000rpm). I'll always find some use for it. |
