  1. I have a box of 20 or so caddies here if you’d like to replace your’s. I could sell you two or three, for spares. Go on, help me empty the box! PM is best.

    Need help with 140 broken hinges

    Shoo goop or any of those similar “goop” products have amazing adhesive qualities. Here’s what I would try: Embed the nut in it, reinforced over top by a thin metal shim/ piece of rigid plastic maybe .75” square, or better if it would fit, with a (small) hole for the screw(s) drilled through, laid on top and all secured to the PB casing by/ in the goop. Assemble thus with the necessary screws inserted, because it won’t move once set, and given that you need to be able to get that screw in there to put the thing together at the end. Dry well. The goop product sets pretty hard, over a few days, but it also flexes once set for years without cracking. The nut, since immediately underneath and abutted to the shim, would not be expected to take all the mechanical forces — those would be transferred to the shim. The shim and goop would provide most of the holding power. You’ll never get that from just gluing down the nut alone, even in epoxy. Betcha it would hold, though obviously you’d have to watch the clearances involved, and the fitment would be a fiddle. Alternatively, someone may have a set of intact PB 145 plastics around here somewhere....

    The daughter card is missing. It connects to the white-ish socket at the left on the first photo. It is a little like a BNC connector, but about ⅓ the size.
  4. There are a handful of us who like the G5, and want to keep the machines running. The rest of you can ignore this post! The following link could be of use to someone trying to quieten a Quad G5, and to prolong its life: http://www.saunalahti.fi/~holindho/g5-quad-v1-lcs-repair.html . Notice the graphs at the foot of the page, as 10ºC lower CPU temperatures at idle and 40ºC lower under load would make all the difference in dealing with fan noise. There are some further links re. cooling systems in the G5 at the bottom. I have serviced three air cooled units (essentially just thermal grease renewal and cleaning out dust, followed by recalibration) with excellent results, and these are very easily done (contrary to what some people think), but the liquid cooled systems especially make people shudder. The writeup takes much of the complexity out of the whole question. I believe that there were two LCS systems in the Quad G5, so be aware of that — your LCS may differ. All the same, the author has documented not only the basic plumbing and mechanicals, but crucially, the presence of sediments in the radiator fluid used after several years, leading to clogged filters. There will be a related need to clean out the radiator and clean or renew the hoses. As in your car's cooling system, the lifespan of radiator fluids is limited, and when sedimentation occurs, the works are bound to get gummed up. The key thing in the LCS is to keep it running optimally, as the temperature thresholds are really rather slender, so this is good to know about. My "new" Quad G5 is still working well, but it could still afford to run at slightly lower temps, so methinks I'm going to service it sometime over the coming months.

    transceiver networking

    Is it connected through a dumb hub? That is often what is necessary.

    What’s that board. IIvx?

    Are vintage injket printers useable still?

    If you are looking for a printer, a StyleWriter 2200 is one of the machines a Newton 2100/eMate most likes to see connected to it, them being contemporaries and all that. The 2200’s cartridges are also easily refilled, as they are just ink containers, with no printhead. You just add (Canon) ink through the hole in the bottom, right into the sponge, until saturated. Getting the separate printhead cleaned out can be a challenge, mind, but it can be done. Your eMate will also print to a Laserwriter, either Postscript (i.e., most of them) or QuickDraw (there was at least one little Personal LW that had no postscript support). It will handle serial or AppleTalk connection as needed.

    Help Identifying SE/30 NIC

    Install A/UX and it should work, plus give you the details with a little prodding. It only takes an hour or so, assuming you have the right gear.

    PRAM battery

    A Compact Mac such as an SE/30 with a (new) working PRAM battery installed: when turned off but plugged in, does it preserve settings by drawing power from the battery or from an early form of trickle power? The reason for asking is that I am wondering whether it makes any difference to the longevity of the battery whether the machine is plugged in or not.

    iMac G4 3 beeps

    Tried 512MB and 1GB, and one of each, top and bottom. Which was quite the operation.... I gather that it will take 2GB, but I don't have the sticks to try. Mind you, if the thing won't boot, there's hardly any point. My question is whether anything other than the memory controller could cause this behaviour. The machine has been put together from parts, so it is possible that, like many a marriage, what I've joined together should have been kept asunder.... It's also perfectly possible that the logic board is toast.
  11. 1.25ghz iMac G4, tried two sets of pc2100 RAM, three beeps immediately on powering on, no screen, both times with each set of RAM. Could it be the memory controller AND is there a fix to be attempted, OR is it scrap?

    Problems with IIsi and Portrait Display

    I have two, one with DB15 (tested working, VRAM complete) and one with 13w3 (untested, as I don't have the cable). PM me if interested in one or both.

    Problems with IIsi and Portrait Display

    I’ve got a couple here with the odd connector, as I recall. Is that what you are looking for?
  14. I'd just clean it with a toothbrush and alcohol, wait 5 minutes, and then use it. The sticker signifies that it was Quality Control Passed, so one has to assume that it was plugged in and tested at the factory, even if the makers did not rise to the level of washing the thing off once it was soldered together. Cheaply made, but it should work.

    PowerBook 1400 Hinge Repair

    I’d probably go with a tube of Goop/ ShooGoo/ other brand names that all seem about the same thing. The tube is large, and contains a clear viscous liquid that dries somewhat flexible, but with an astonishing holding power. It would do for both the crack and the brass thingie. I’d let it dry for a week or so before reassembly, and I’d also overfill slightly to maximize surface contact. Recently, the leg broke off my daughter’s glasses at the metal hinge. They were irreparable. New glasses had to be ordered, which involved waiting for an appointment, etc., so while waiting, I glued the leg back to the frame with this stuff, in a simple butt joint. The joint was made in just a tiny physical area, but Goop held that pair of broken glasses on her head, with them being removed and adjusted and so on, for a week or more until her new glasses were available, and then they made it home in her handbag, still holding together. There’s no way that an epoxy adhesive could have withstood the flexing and held in the same way.
  16. I've always found the zip drive/disk (100mb) very useful for old Mac tinkering, I have to say. Never had one fail, but I will confess that my usage is only occasional, for software installers and the like. Back in the day, a 100mb zip was serious kit. My hard drive in the early 90s afforded a grand total of 80mb of storage.

    AAUI to Ethernet and System 7.6 - am I missing something?

    Use of a "dumb hub" is generally recommended for IP networking on 68k era hardware. A surprising number of my stash of AAUI transceivers are also borked, so in my book, that's another thing to watch out for.

    about powerbook 170

    Did I not say unto ye, that if ye search, ye shall find? https://www.macintoshrepository.org/2449-mac-system-6-0-8-for-powerbook-140-145-and-170

    about powerbook 170

    The 170 will run a particular iteration of System 6 (if you search, it will come).

    68LC040 in Centris 660av

    From the old AV Mac FAQ: ”[AV] FPU (floating point unit) bombs Of crashes attributed to the lack of a FPU, Noah Price (noah@apple.com) has one theory: It can be caused by applications that are not fully 68040 cache compatible. To test this theory, use the Cache control panel from your Tidbits disk to turn of the 040 cache and see if things improve. If the 040-cache is not the culprit, open the case cover and make sure the CPU is not labeled as a 68LC040. Apparently the wrong CPU was used in a very small number of machines, for which a replacement will be provided. However, the problem can also be caused by bad or poorly seated DRAM, remove or re-seat the SIMM's to check.” Source file https://imagej.nih.gov/nih-image/download/documents/av-faq-156.rtf Evidently the 660av is meant to have an FPU.

    Classic II + FPU = A/UX?

    A/UX is very hardware-specific and can't even run bog-standard accelerated Nubus video cards of the period, including Apple's own. You'd have to be a genius to get it to run on a Classic II, in my view. Much easier to run it on an SE/30; on an SE/30, mind, it (v.3 at any rate), makes only plodding progress. An SE/30 might do better with v.1 or v.2 of A/UX, which were issued in the 68030-era.

    9600 Floppy Drive

    You could try cleaning and lubrication first. It only takes about half an hour.

    Connecting an Imagewriter II to a OS 9 Pismo?

    What I'd do is set up a print spooler in A/UX. Where's the fun in a dongle? Seriously, that's what I'd do. YMMD.

    Building the fastest Power Mac 9600

    What is the performance of the stock machine like when running Tiger? And would your build (made on a dual G5) run both processors of a dual 604e card, do you think? Or is that a limitation in xpostfacto?
