    System 7.1.1 Pro

    To the best of my fading memory, System 7.1 Update 3 is not synonymous with a System 7.1.3, wot of there never was one. However, there was/is a Finder 7.1.3. Some reference to the matter can be found at http://68kmla.org/forums/viewtopic.php?f=7&t=8770&p=89204. I have used such a retrofitted System 7.1 in a RAM-throttled Colour Classic (recte a Performa 250), as well as in a IIci (with umphed-up RAM), but the IIci Macs have now all passed-on to OS 7.6.1 in keeping with their DayStar 030 and 040 cards.

    What Richard needs to absorb while he is yet new to privation (groan ...) in this Army, and well before he can be eligible for PFC status, is the difference in use and outcome between winklage and wigglage as investigative or restorative methods. Winkling cables away from snags and out of tight places is wise. Wiggling pins and connectors is, conversely, as both tomlee59 and Osgeld have more than hinted, a case of if it isn't broken before you start, it has a good chance of being so when you finish. de

    HELP! Lost and Not Happy :-(

    The last retail OS 9.2.1 CD that I have is ©2001, and we were invited to download the update to 9.2.2 when that became available. I'm not aware of any retail CD of 9.2.2 at the turn-of-Century, although I have not looked assiduously since then. OS 9 was included in ex-factory installations and system-specific CDs and DVDs for years after 2001, at least until Jan 2004. The retail OS 9.2.1 contains Mac OS ROM v8.4 at best. The update to 9.2.2 had advanced to Mac OS ROM v8.7. eMac system-specific CDs provided v9.2.2 of Mac OS ROM. The MDDs that could boot into OS 9 had Mac OS ROM 10.2.1 (with 48-bit LBA support. Don't nobody search these forums no more?). Side-by-side with Mac OS ROM's maturation were changes to the three elements of Classic Environment (2) and Classic Compatibility ROM, which in the MDDs' case, had progressed to v2.2.1 and 9.5.0 respectively. What else these little critters enabled/disabled has to be discovered by suck-it-and-see methodology, but I can say that the version of 9.2.2 from the MDD era is as stable as a rock on Macs as far back as my two Beige G4/500MHz and 9600 G4/800MHz, and on my G4/733MHz DA. What is a necessary fiddle is to replace Apple's versions of Radeon (OS 9) software with the (later) versions from ATi. In either case, however, if you are using a Radeon 7000 (PCI or AGP), kill Graphics Accelerator. Kill. Kill. de
  4. Perhaps as a result of my ineptitude with the search engine, I have seen/found no current/prior reference in these forums to this sale on eBay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330360490902#ht_720wt_1055 EveryMac makes reference to the marque, of course: http://www.everymac.com/systems/powertools/infinity/infinity3240.html I was curious as to why the eBay offering might have needed to be held—almost as if just the isolated rear and front panels were available for display—while it was having its picture taken, and bemused (as well as amused) at the left-right inversion in the pictures of its rear panel. Making the mental back-transposition, I was struck by the similarity of its style of fabrication (and architecture of the MLB) to Power Computing's PowerTower Pro, the only PT machine that I know in the flesh, as it were. An ambitious asking-price, too. de

    Lead on some older hardware

    That seller's pricing policy has attracted comment before. In the new-look comments-allowable regimen the comment cannot be repeated. The pic doesn't allow much confidence that anything has changed in the seller's emporium, however. de

    Power Mac 9500 startup woes

    As both trag and Charlieman have written, reset the MLB. Not a desultory random poke at the CUDA. The CUDA is the last thing to touch before putting the metal cover back on, with good battery (3.3V or more in circuit rather than in the hand). Its job is to provide a clean-slate inventory of the hardware to the system. Pulling the Mac completely apart will have gone most of the way towards reseting the MLB, but there is more to attend than that, in that your daughter card must be properly bottomed (which may take considerable force beyond the first stage) in its slot, as must a video card in its PCI slot. Every breakable/makeable connection along the top of the MLB must be attended carefully. SCSI power, data connection and termination must be scrupulously ensured. Your original RAM was almost certainly FPM if it worked, even if unpaired, and you must take care not to use EDO alone or mix EDO into an FPM installation, despite that EDO is FPM with pretensions (such as pipelining). Then, having cleaned, polished, blown out, plugged, installed and rechecked everything in sight, and avoided snapping off as many of the snapdoodles as is humanly possible, install the PRAM battery. Wait 10-20sec, and then hold down the CUDA switch for 40-60sec. as your last act before recladding the box, plugging in externals and reconnecting to the mains. Use the soft-power switch on your Apple Design or whatever keyboard for startup. Note down the sequence of events (or non-events): chime, raster, Happy Mac, pointer, splash screen, march of the extensions, desktop. Record your success or the poop-out point so you can post whichever. Rots o' ruck. de

    Quadra 950 (+ WGS95 card)

    What I take to be the on-board cache of 128kB of SRAM (which Chipmunk doesn't go into in any detail) is all surface-mount chips: 16244CTPV by Integrated Device Technology. What is on the TAG and cache card(s?) is all DIP (through-hole) chips without legible markings. Given the discussion in the referenced thread, these latter, especially as made-up 68-pin cards, may be every bit as scarce as they seem to be, yet it is difficult to believe that the cards were made only to populate Apple's output of WGS cards. Perhaps Unknown_K, who may have gone more deeply into the matter, can finger both the maker of the SRAM chips and of the cards? de

    Quadra 950 (+ WGS95 card)

    Kindly rub your throat along the edge of my outstretched index finger. The only reason that you got it at all, let alone so cheaply, was that the seller did not deign to respond to my request for a pic. of the WGS card. I was, of course, interested in its cache and TAG cards. Grrrr! Do enjoy your acquisition, but don't pass any dark alleys at night while you are alone ... viewtopic.php?f=20&t=8044 de

    Mac II ROM Interchangeability?

    As LCGuy relates, in addition to insertion of the replacememt ROM chips: HI (342-0639) at C13 MED HI (342-0640) at C12 MED LO (342-0641) at E13 LO (342-0642) at E12 the IWM chip must be replaced with a SWIM, but you also need System 6.0.2 or higher lest the Macintosh II still mistake the high-density drive as an 800kB mechanism. de

    Appleshare crashing on 6.0.8

    Some of the posts above indicate sources of Mac OS ROM 10.2.1 that I was unaware of, and wouldn't have been accessible when I was trying to get a useful installation of OS 9.2.2 going on an MDD. My subsequent experience is that: Large drive support under OS 9 can be checked by looking in System Folder for the version numbers of Mac OS ROM (10.2.1) and the three Classic support modules Classic (9.5.0), Classic Support (2.2.1) and Classic Support UI (2.2.1). Without that ROM-in-RAM version the System knows nowt about 48-bit LBA and drives of more than 128GB (real), regardless of a PCI card. I've never used 10.1.x on my MDDs—only 10.4.x and 10.5.x—so I have no idea how it behaves with large ATA drives mediated by the on-board controllers. However, a drive of 190GB remains the limit for OS 9 to address (by other than FireWire), as also is 1.5GB of RAM a limit. Mac OS ROM 10.2.1 (and the other bits of the Classic Compatibility Environment) also came on the G4 MDD (machine-specific, grey) Install CD, but it was otherwise hard to find. Nay, it was impossible to find it. Things may be different now, but I could never find 10.2.1 in the Apple basket when I was looking, so you may need to chum up with someone to get it. It may also be that the change from BootROM 4.4.8f in the earlier MDDs to 4.6.x in the FW800 and later MDDs torpedoed booting into OS 9.2.2. de
  11. I have a soft spot for towers, but the 6500's case has never enthralled me. Since the DE is peculiar to Australia, it is the pick of the two, I suggest. My DE comports itself very well with a G3/400MHz L2 card and max. RAM. TV viewing is adequate, but more 'how clever that Mac is' than enjoyable. It's a middling-accomplished Mac, but it is a DE. de

    SE/30 schematics?

    Bomarc Services, of PO Box 1113, Caspar, WY 82602 produce(d) some, and may be able to help you with MLB and PAB schematics, at a price. There are no internals shown for the SIMMs, but memory control is addressed (pun intended). de

  14. Before you worry overmuch about the third NuBus slot, why not fill the RAM slots with 16MB 80ns cards, and the cache slot with a DayStar 50MHz PowerCache card at minimum, or an 040 card by DayStar, MicroMac or Mobius, or a DayStar 601/100MHz? Drool. Price and cool usually go hand-in-hand. de

    ADC display for a Power Mac G3

    I am using a 17-in Apple Studio LCD with an Apple DVI to ADC adapter from an ATi Radeon PCI 7000/32MB (VGA, DVI-I, S-Video) card in a Beige G3 (Rev. C) MT with a Sonnet G4/800MHz/768MB upgrade and a 2-port (NEC chip) USB 1.1 card. Works well. The slowest redraw occurs as raster appears during booting, but is never thereafter a difficulty. The System is OS 9.2.2 with Mac OS ROM v10.2.1, purloined from the MDD G4 installation CD, and with the mods to the ATi extensions mentioned at: viewtopic.php?t=822&postdays=0&postorder=asc&start=25 de
