Actually a T-15. I had at least a dozen of them specifically made for this kind of thing, but I haven't been able to find them. Not that they are needed... Find one of those nice screwdriver kits with the torx bits and the extensions(make sure they're skinny enough to fit in there with the screw). Works fine for me. To get the case open I usually use a screwdriver(don't do that if you like having a spotless case), or sometimes they're loose enough to just pull apart(that doesn't happen very often). It can be done, but not easily. You need some interesting brackets, I think they usually stick them sideways against the case above and behind the floppy drive, or maybe the ones that just push it back a few inches but mounts to the floppy drive bracket(I've used them in an SE, not sure if they would fit in a Plus). And of course you have to get the SCSI and power cables hooked up. Not sure about the power(I think I've seen some splitter cables off of the logic board connector for this function), but the SCSI needs to be hooked up out side and somehow ends up inside, either through a slot cut into the case or if you want it a bit uglier, you can figure out how to get it through the battery holder. -------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | orham(a)qth.net list admin KD7BCY | | ham-mac(a)qth.net Portland, OR | --------------------------------------------------------------

I usually just grab on the sides and pull suddenly. The inertia/shock usually separates them. The welding clamp works the same as the "Special Tool." You're right about not easily, on the SCSI cabling. I did this with a 4-meg RAM MacPlus, once, and my solution was to cut an extra port through the back, above the MacPlus's external SCSI port, mount a male DB-25 through the new port, and put together a female-to-male connector externally, with an extra DB-25 female between the two, facing outward for adding external SCSI devices. Pay attention to pin 1 on the short external cable (it comes out upside-down, I think). For power, the MacPlus's power supply is adequate, but I recommend beefing it up as per Larry Pina's "The Dead Mac Scrolls" or one of his other books (I forget the name). The hard drive I used was a 3.5-inch low-profile, and I mounted it on top of the floppy housing, slightly back to avoid the monitor tube. You have to make the internal cable, also, yourself (or at least, I did). I was worried about temperature, also, so I mounted a 2" fan on the right side, and drilled a pattern of holes on the right side for air passage. It worked out to quite an elegant solution, that I was proud of; it was nice, being able to carry it around as a single package, with the handle. I ran a BBS, off of it. I gave the unit to a girlfriend, whom I met during my first Internet experience, on AOL (Hey! It was my finest computer!). I think the HD was, like, about 120 megs, but you could easily put a 1 gig drive in (or larger), these days, if you think you need it. Internal drive is terminated, as is the last external device on the chain.

I ended up getting my long torx bit at a local auto parts store. <<<John>>>

As (possibly) the "other list member" I want to point out that my bid on the item was purely coincidental. I was scanning ebay for "tube" stuff and found the item. I buy (or at least ATTEMPT to buy) some old tube stuff on eBay, and it was just a lull in some other activity that allowed me to scan the auction. I am not sure where I stand on the "notify the list" issue, since something juicy (that I want more than someone else) just MIGHT come to my notice this way... Many times it does help scuttle a deal someone else is zoning in on. Both can be good or bad (at least bad for the seller.) But in this case, it "wasn't his fault."

I *think* I've got some of these, or something very much like it, stashed in a box at my parents house. About 20 years ago, I bought a couple boxes of "surplus military computer parts" at a surplus store in Omaha. Among the parts were several boards that look like the picture shown on this auction; a circuit board perhaps 8x10" or so, covered with resistors and wax sealed caps, with a metal "faceplate" on one end with perhaps 5 or 6 tube sockets and a steel "grab handle" mounted on one end. Does anybody know what else might have used modules such as this? I will try to grab them the next time I'm out there, although it may be a couple of months.

Functionally the only real difference between a Mac Plus and a Mac SE is the SE is designed to hold an internal HD or second floppy, and the SE introduced ADB keyboards and mice. Hmmm, guess that means the iMac is the SE of the 90's :^) Zane | Zane H.

I still have to boot my Plus from floppy, so I never went past the original system that came with it. Some day, when I actually have free time, I'll have to try 7 on my Plus. BTW-- does anyone have the original Mac OS disks? I have a 128k and I would like to boot up to the original OS when I demo the machine for school kids. I think I have a MacPaint disk and a MacWrite disk somewhere, but no system disk. Thanks.
