  1. The "squirrel cage", also termed the "rat cage" by some, was phased out in early 1988. The noise wasn't the principal complaint, however. Many felt the fan was responsible for screen interference; this could have also been the result of the horizontal-facing video board (which isn't recommended for the newer fan, either). I have also witnessed this firsthand in SEs, long before the capacitors became the chief concern among SE analog board problems. All SE/30s left the factory with a blade fan, but it is theoretically possible to put the old analog and video board combination inside an SE/30. As I recall, Apple offered a fan replacement program for some time for SE owners. It must not have been all that popular, however, as I don't see many 1987 SEs with the newer fans. Apple used two blade fans in North American SE models. There's a DC Pico Ace 25 and an Elina-Fan. The Elina seems to be the slightest bit quieter. Of course, the real noise factor can be a hard drive. Both the MiniScribe and older Quantum 3.5" drive, usually installed in an SE with a factory hard drive, were notoriously noisy drives. (However, perhaps to compensate, the SE has a speaker which projects better than any compact Mac as a result of placement and front bezel design).

    Imagewriter II ribbon cartridge sources?

    @maceffects, if you need a guarantee for someone who will buy a ton of ribbons, look no further. If all the kids decide to use Kid Pix when I have the lab set up, I can plow through one or two a month. (It also teaches patience when this happens...remember the "Waiting for AppleTalk ImageWriter" message on the network?)

    LC575 screen

    Regarding 13 vs 14 inches...that actually comes about because of how Apple used to measure monitors. The 13" and 14" Apple Trinitron displays are the same size. The reason? When the Hi-Res Display first came out, Apple measured by how much was actually viewable, assuming the height and width were set to the defaults (with the black border around them). Many competitors only measured the size of the physical screen. Sometime around 1993, that changed, and the extra inch was tacked on despite the monitors being the same size, both physically and in terms of viewing area. The 575 display should fit fine into a Macintosh Color Display, which was the Trinitron standalone from the same time period as the 500 series. It may also work with the Hi-Res Display, Apple's earlier Trinitron product. Since CRTs are hard to dispose of, both from an environmental and legal standpoint, it's worth keeping, especially if you do acquire one of those displays or another 500 series someday and find it's in need of a display. The CRT itself usually lasts practically forever; other components in the monitor itself can go and if the CRT does need replaced, it's going to likely be from a scratch, burn-in, or some phosphor issue caused by overuse (though I've rarely seen this on Trinitrons, both TVs and computer monitors).

    Apple Imagewriter II Restoration

    Could Ultrasonic work on a StyleWriter I? I've got one that won't print from any cartridge.

    Discharging a CRT - video

    Great video!! If I'm going to work on a Plus or earlier and need to work with the CRT, I prefer to leave things unplugged for two weeks. In addition to keeping the Mac off, I'll actually unplug it. This should get rid of almost any buildup in there, but to err on the side of caution, discharge the CRT. The self-discharging bleed came in the SE and later. I know the SE and Classic lines have it and can confirm the 12" RGB (the LC topper monitor) does too. I don't believe any of the Plus boards had it, even the platinum switch ones. Apparently some early SEs don't have it, but I seem to remember a self-discharge in a 1987 SE with the old rat cage fan.

    WHAT FONT? "can't wait to get out of that bag"

    The font in question is Athens.

    Repaired Apple ADB Mouse switch

    We had one fail at our school back when the wedge mouse was the current model. The switch was stuck in the down position. The Mac Classic it was on wound up rejecting every single disk--until the mouse was disconnected!!

    Platinum 512ke?

    Here's a video of an ED with the platinum case. It's not quite the 512Ke you're looking for, but it's the right color and has the 512Ke badge (though this one is sort of yellowed).

    Platinum 512ke?

    Most sources I have read have pinned the discontinuation date of the 512Ke as September 3, 1987. It could be possible it was pulled from production in the United States at an earlier time (summer 1987) but never officially discontinued. The platinum 512Ke is for real. It looks like the Plus, with the Apple logo mounted inside the case itself next to the floppy drive and not on the little square in the lower corner. There is no name next to the Apple. They are also very rare, having been made for a few months in 1987 and selling mostly to educational institutions. The Plus had taken over as the low-end Mac and most people who wanted a step-up machine were buying the SE, not a decked-out Plus. I once owned a 512Ke with the ED badging produced in 1988, which I purchased from a Dutch seller. It was platinum (albeit yellowed enough to look beige). Apple's discontinuation dates should always be taken with a grain of salt for these early products. They only cover North American models, and even then, they aren't particularly accurate. Here are some additional examples: --The SE was made into early 1991 despite having been "discontinued" in October 1990 --The LC II was made well into 1993 despite having been "discontinued" in March 1993 (and even got the LC 475-style case in some markets) --The Plus was "discontinued" in October 1990, yet production ended long before that (even the third edition of the Mac Bible indicates this) --There are Classics out there with 1993 dates (original, not II) which seem to have reached non-North American markets. I know I saw one from a South American nation, not sure which one offhand. --The Apple Keyboard II is sometimes listed as being discontinued in 1993 or 1994, yet I've seen press photos from far later with it (even as late as 1996). It did lose its colored Apple logo along the way. --Nobody seems to know for sure when the final ImageWriter II was made, but it appears to be at some point in late 1996; I have personally seen dates as late as 1995

    Hate to do this but... SE/30 Help needed

    Do you know if this Mac has been re-capped? If it hasn't, that's your first step. Every capacitor on the logic board should be replaced.

    IIci behaves like a compact mac

    Would the same trace also be responsible for a IIci that wants to stay on all the time? I had mine re-capped eight years ago and it's had this issue since (otherwise, it works like a charm). If I plug it in, it comes on. If I turn it off, it comes back on a few seconds later. The switch isn't turned; I do know they can be rotated to keep the machine on (honestly a great feature since they were popular server machines). Also, speaking of caps...if your IIci has a cache card, recap it!! I had a cap burst open with smoke on mine. I believe the card has two caps offhand, not sure the size as I don't have the new one I just bought this past weekend handy...

    HD Access LED Size for NEWER Quantum ProDrive LPS?

    Yes, the LED on the outside of the case.
  14. I have a ton of old ProDrives which I am using in my various Macs. (Yes, I'm a purist and will use these hard drives as long as I am able to maintain them). I keep them in working condition, but have one minor issue with the LEDs... The plug for the access LED is a smaller size on the newer ProDrive LPS. These bear a copyright date of 1993 for the EPROM but otherwise look and sound like the 1990 LPS model (commonly found in the LC). They are NOT the old bulky ProDrives from the 1980s with the big red connectors--these are the white ones. Since I can't go to Radio Shack to size these anymore, does anyone know offhand the size of these LEDs so I can order one? I put a newer drive in a Iici and the old LED no longer fits--it's too big (yet it will work on any of my other ProDrive LPS models from the early 90s).

    Re-cap gone wrong.

    If your hard drive isn't getting powered, it's almost certainly a power supply issue. I had an LC that was going through this same process and a re-capped power supply solved the problem. I had another LC on which the hard drive wouldn't even power up sometimes. Again, a new power supply solved the problems (as well as a video problem that couldn't be attributed to the main board, which was re-capped).
