  1. The drive heads could be stuck and that's generally a pretty easy fix. I had a similar Conner hard drive - if you're careful and take the torx screwdriver to open up the top in a relatively dust-free environment, then plug it in and power it up, you may see that the head is stuck. You can see an example of this on YouTube here. It could also be stiction, which there are other little tutorials. Would be neat to try and revive the guy. And naturally replace with a SCSI2SD or RaSCSI if you want!
  2. Definitely worth giving the logic board a bath. Some people get testy about boards going in the dishwasher, but I've been very pleased with dishwasher results (please no soap or other dishes) . Scrape that orange barcode sticker (if you feel the need to keep it) in the board corner off if you do any bathing, as it'll likely disintegrate. Washing that case top and bottom (no components when washing them) and carefully wash/clean/lube the floppy drive would give me a lot of hope. And sometimes washing actually rehydrates the capacitors enough to bring it (temporarily) ba
  3. Searched all over the forums and can't seem to find where the actual speaker diameter for the Mac SE case is. I don't have any calipers or my Mac SE on me, so, I'm having to ask the community (and hopefully help whoever might ask the same question in the future). Is it 60mm? 55mm? I have no idea and need your help. I'd like to know because I'd like to put in a modern, higher power/wider range speaker into the same slot as I build something usable with the same Snow White industrial design. FYI - it is a Mac SE/30 that is beyond economic repair due to expl
  4. Gang, Everyone likes to talk about how the SE/30 can go to 128MB of RAM and is a wonderful flexible machine with the Mac ROMinator II, etc. But has anyone tried putting those 16MB SIMMs into the two-slot Classic II logic board? Pushing it to 34MB of RAM would be cool. If it's a ROM limitation, though, then I ask - Is there the possibility of a Mac ROMinator III for the Classic II that would replace the ROM chips rather than be simply on a ROM SIMM? (Kind of a later version of the ROMinator I) Steve? Doug?
  5. If they're willing to let you open up the case (long Torx screwdriver, four screws, pretty easy to open up) and inspect the logic boards, then you can determine whether they're worth it or not. If the battery exploded and leaked all over the board corroding the circuit traces, it's game over and likely not worth the investment.
  6. I know it's late, but SE/30 (and other Macs using 30 pin memory!) does not care about parity or non-parity memory and often parity memory can be had reasonably cheaply. I bought this and was very pleased at the quality, warranty, and price: https://www.18004memory.com/16mb-60ns-fpm-30pin-simm.asp?l3id=842 There's also an eBay ad for them but it's at a higher price: http://www.ebay.co.uk/itm/330590859970
  7. Ahh, yes. But that being straightforward, couldn't replacement ROMs simply be programmed with an ordinary ROM programmer?
  8. Whoa, well done! Was thinking "hey! My work is done!" but I think you were going the other way around and also using the smaller form factor PLCC pinout rather than the SE/30 44-pin PLCC to the SE 28 pinster. Thanks for confirming my theory of swap-eration!
  9. See that adapter? Think about it as a little bit of inspiration. So, the SWIM chip as we all know is an upgrade to earlier Macintosh SE machines that were equipped with 800k drives and was once an upgrade option for users who want to read and write 1.44MB floppy drives. I'm now an owner of a battery-acid-victim SE/30 motherboard and was wondering about what could be used as a donor for other systems. I am also in possession of an 800k Macintosh SE overseas and was just fantasizing about using the SWIM chip and SuperDrive from the SE/30 in the SE. First problem: form factor. The I
  10. Exactly the one. Wow. Some sadistic chemical engineer from Maxell is laughing still!
  11. In a pinch you can use zip-ties (cable ties) and/or a piece of gorilla tape (or similar) bound against the other SIMMs to keep the tabless SIMM upright and within its slot. Probably best to get a period-correct SIMM slot if you are wanting an authentic restoration. I have a donor SE/30 logic board (battery explosion) that could be used as a donor for your needs. Let me know.
  12. FYI - (dish and others) Soap is a base, which neutralizes any kind of acid that would be active (if there were any left - the battery and its holder were removed if you noticed in the photo). Note that the acid basically wore itself out eating up various components and is no longer active. Lots of people use the dishwasher to clean electronics components - if this was a legitimate concern, the practice would not be as popular as it is with many repair communities. Thanks.
  13. Dang. Sorry to hear the news. Well, I've got a mostly happy Mac SE/30 with a repaired Astec power supply (had to replace the input filter caps with modern versions) that does NOT have an ethernet card, which this Mac will donate. Would it be worth swapping in the Sony power supply from this Mac? The external case appearance is in good condition, and even the rusty bits could be sanded down and primed, so it'd be a shame to completely trash the lot. Ultimately I guess I'll chalk this up to a slightly expensive and convoluted Ethernet card purchase. I think I'll throw it in the dis
  14. I took a risk on a non-bootable SE/30 in the hopes it was just a dead hard drive. Well, the hard drive works. And it came with an Ethernet card. The Sony power supply seems to be working fine, and I would imagine the screen is probably OK too. But sadly, the logic board does not due to a battery acid exploding some time when Michael Jackson was still alive. And that thing, it caused some of the frame to rust, caused part of the interference-shield cover to get eaten away, and frankly was pretty impressive on how much evil was originally contained in that battery. I thought to t
  15. So, not sure if anyone actually controls the 68kmla infrastructure around here, but the Certificate just expired on the wiki. It might make sense to go with the free LetsEncrypt SSL cert and automate the renewal if that helps?
