  1. Bummer. The only one I'm really confused by is "M," but the bigger question is what the Macs are looking for that the drive isn't giving them, which I don't understand at all.
  2. Well, I'm afraid that datasheet has me completely lost. I know pretty much nothing about reading this stuff, but here's the various bar codes/ID strings on the drive: L1 B3B 192222 FRU PN 92F0428 EC895987 PN45G9490 E150455 LR34074 R9371775 SN 13 192222 S3 ESP2242411 FSP45G9883 EC 895964 4.0 Type 0662 Does any of this clear anything up?
  3. Well, I have obtained a new hard drive for use with the SE/30. Unfortunately, that means more contending with the vagaries of SCSI configuration. Here's how it's sitting at the moment. The drive I bought is an IBM 92F0428 1GB drive (looks from what I can find like this is just a re-branded Maxtor.) Going by the label on the drive, there are five valid jumper positions: three for ID, one for termination, and one labeled "M" that I have no idea what it does (can't find any documentation for the drive, either.) When I hook it into my SE/30, HD SC Setup gives me the same spiel about being unable t
  4. Yeah, I suppose. Never re-capped anything before, but there's a first time for everything...
  5. Ah, that'll be interesting to address. Wonder if I can get a replacement analog board for cheap...
  6. Okay, after obtaining the mother of all Torx screwdrivers (18" blade! Longer than the computer is deep!) since I couldn't find a more appropriately-sized one for cheaper, I opened up my SE/30. Tried replacing the hard drive with the one from my IIsi, and it booted halfway before complaining that it didn't have the right system software, so it looks like the hard drive is indeed the problem. Which is okay, since it's only a 40MB drive and I was wanting to put something a little bigger in anyway. One other question: the sound is very faint or entirely silent, even when I turn the volume up a
  7. Looks like it's a System 7 app, so I'll give it a try and see what happens. I finally broke down and purchased an extra-extra-long shank Torx bit, so I should be able to open the computer up for a look in the near future.
  8. Hmm. Version 5.2 is the version of SCSI Probe I can find, but it claims to require SCSI Manager 4.3, and I'm just about out of space on the disk tools floppy. Is there an earlier version that doesn't require it? Where could I find that?
  9. No luck with the patched version, either. I think I might just have to shell out for a long-shank Torx bit...
  10. Okay, got it home from the recycle center and plugged in. I know it has a hard drive installed, since I can see the activity light flashing and hear the disk rattle to life on bootup, and it attempts to boot from the drive, but can't actually boot; I get the question-mark disk icon. No big deal, I have install disks. The problem is, when I boot from floppies into System 6 or 7.5, it doesn't display a partition and can't find a valid SCSI device in Hard Disk SC Setup. Is there a way to figure out what's wrong, short of tracking down an ultra-long Torx screwdriver and opening the case for a look
  11. So I've just come into possession of a Mac SE/30 :b&w: Having a thing for the old compact Macs, and this being the best of the bunch, I'd like to try and get it all clean and beef it up a bit (ideally, I'd like to run Linux/m68k on it, just for fun.) However, I'm slightly confused by this whole PDS thing. It looks, from Wikipedia, like the PDS slot exists in a number of mostly mutually-incompatible versions? One reference I looked at suggests that the SE/30 and IIsi share a PDS version, but another section implies that a later LC version is backwards-compatible with an earlier version, so
  12. Hmm. Maybe I'll try the 27 first and then the 25 if there's any noticeable trouble.
  13. So I've been looking at putting a new clock crystal in my IIsi to get the full 25MHz out of it. I notice on Marc Schrier's page that you can get it up to 27.5MHz with the appropriate crystal, but any higher causes problems with the floppy controller. My question is, is there any reason not to take it up to 27MHz?
  14. Hmm, wow. I did turn on 32-bit mode during the initial cleanup, but I guess the PRAM battery failure kept it from sticking. Well, all the more reason to hurry up and get a new one. Thanks for the help!
  15. Well, I recently came into possession of a nice little Mac IIsi. It's in nice shape and runs fine, and some previous owner put a whole 16MB of RAM in it (plus the 1MB on the motherboard,) so I should be comfortably set for some 68k goodness ...or so I thought. I got System 7.5 installed from the disks that came with it and got some software copied over. Problem is, System 7 is taking an absolutely ungodly amount of RAM, leaving about 6.5MB of the 17MB free for applications. I spent a while disabling unnecessary features and extensions and got it down to a much more reasonable 2MB. Proble
  16. I've actually had the same problem with my LC and Classic II. I opened up the LC to see if I could figure it out (didn't have a long enough allen wrench to open the Classic ) I traced the noise to the internal speaker; sure enough, when I plug something into the headphone port, the speaker is disabled and the noise goes away. As near as I can figure, this is RF interference between the speaker and the fan, which are right next to each other on the LC board; I don't know if this is also the case with the Classic (though I suspect it is,) and I don't know why it would do it now when it almost
