    Large volumes in a 68030

    Got my adapter, the same as linked but from different seller, and IBM U320 drive. Didn't think about the terminators! Plugged it all in and the drive doesn't even spin up. No terminator but I don't see how that would prevent the drive from powering up. I guess my options are buy another drive and or adapter to see which one is the issue, then return the defective item. Well before that I'll try a different machine and just plug the drive/adapter into an external power supply. Any other ideas?

    Thanks! Not sure why I haven't heard of the adapter/2.5" ultra320 combo before but I'm glad I just did. $32 shipped for both is what I paid.

    Which adapter do you use for this?
  4. I always saw those monitors paired with the 6100 and to me, that's the only proper fit! Since it has the squid it will work but wouldn't it look a little small next to the massive 950?

    Finally decided to take another crack at this thing. It's been 5 months since I opened it up but I wasn't able to find any manufacturer name or other markings without taking the board out. However, the board would not slide out since the add on card was too tall and the surface mount components were hitting the chassis. Had to bend the side of the metal out and pop the board out from the bottom. Check out the board, a few cool things going on here: It appears to have 2 separate upgrades. First is the 2 Meg "Fat Mac" upgrade from Perspect Systems Inc. out of Venice, CA: Not too much out there about this company, but did find this ad in MicroTimes from 1986: https://archive.org/details/microtimesvolume00bamp_14/page/n21 The case also has a cooling fan added to the rear vents with power tapped from the analog board. Not sure if this is separate or part of the Fat Mac upgrade. Also found this reddit thread for someone else who apparently found one of these. https://imgur.com/a/bemqL Second is this SCSI board from Julian Systems Inc. This is my main focus at this point. I unplugged the SCSI cable but didn't remember or document which way the cable was installed. It has a red stripe on one side for pin 1 I'm guessing, but this SCSI board isn't keyed and I'm not sure how it goes back on. I suppose I should look at the SCSI pinout, find a ground or something and follow a trace on the board. Have to do some more research but not plugging it back in until I'm sure its right. @unity Yup, you were right, the battery area was shaved for the cable to go through. But I reinstalled it, the cable got pinched a little. Bummer. It doesn't look bad but a simple continuity test should confirm it's ok. Another shot of the board showing overlap between the ram board and SCSI. While I was attempting to remove the board from the chassis, the ram board actually pressed down on the SCSI board and it unseated it from the rom socket below just enough where the Mac wouldn't boot, just showed checkerboard on the screen. Re seated it and everything was ok but there was a moment when I got really disappointed, thought I killed it! Here is the 2048K as she sits now. Still got a lot of work to do, none of the drives eject, gotta figure out the SCSI cable, its a bit dirty and there are some cool peripherals that came with it that I can't wait to try out. But I think that will be a separate thread. Just thought I would update this thread since I wasn't able to find much online about this setup. And thanks to @Dog Cow for the work on his 512k site, lot of good info that helped me through this process. https://macgui.com/news/article.php?t=470 https://macgui.com/news/article.php?t=471

    Boxed eMac acquisition!

    Update your sig Cool find, looks like its in really good shape. That box is done, I wouldn't feel bad about tossing it. Got any specific plans for it?

    How bad is the damage?

    Have a Classic I recently acquired. It will chime 1 out of every handful of times you attempt to power it on, otherwise it just acted like it had no power. When it did boot the video would cut out intermittently but ultimately I would get a solid picture and it would blink the ? disk. Opened it up and found the carnage below. Is this worth a repair attempt? Aside from the chassis damage, looks like just a few components were damaged that could be replaced, D1, D2, C70. Might as well recap while I'm in there. No visible damage on the analog board. Since it did boot, I'm hopeful that component replacement will yield positive results, however, this would be my first major repair like this on a Mac and I'm looking for opinions from those who have more experience with these repairs to chime in. Is the damage bad enough to scrap the board or would a repair work? Also, that leak from the CRT, what is that?? Thanks all.

    Help resurrecting a 7500/100

    InstQuick update on the progress: Installed the PCI ATA card in the 7500 and attached a working 4GB drive from a beige G3 desktop but it did not boot. Booted using a 9.1 CD, ran drive setup but the drive did not show up there either. Put the ATA card in the G3, same issue, no boot, does not show in drive setup. Loooong story short, ended up swapping drives, cables, PCI slots, drive jumpers etc. etc. etc. only to find out that the drive actually shows up in drive setup but as a SCSI non-initialized drive. Awesome! Yeah if i would have just skimmed the included instruction manual in the beginning that would have saved me a ton of time since it called out that fact. The manual also mentioned that it would only work system 8.6+. However, I got it to boot on system 7.5.3 successfully! I pulled a spare 40GB WD drive from a PC and connected it to the 7500. Booted the 7.5.3 CD but drive setup would not detect the drive. Booting from the 9.1 CD, drive setup sees the it as SCSI non-initialized. Using drive setup I initialized it using HFS Standard and a 1GB partition to start. Booted 7.5.3 CD and after initialization, the partition shows up! I was then able to fully install and boot 7.5.3 (my OS of choice for this Mac) Last issue I'm working with is packaging. The standard length IDE cable has no easy path from the PCI card to the drive I've installed in the front bay. I believe it will be as simple as finding a long enough cable to go from the PCI slots to the other side of the case where the SCSI cable enters the drive cage area, then to the drive. I'm estimating it needs to be 24"+ to make this happen. If I were to install the cable over the drive cage the case would put pressure on the cable and if I had a CRT sitting on top, it would likely damage the cable. After that's all buttoned up, I'm planning on running some benchmarks to see how much the Ultra ATA card and drive improves performance over a SCSI drive. I have one from an 8500 that I can just swap in for testing. That's it! Just wanted to share the success and add the tidbit of ATA info I found along the way.

    Wow just realized that the link I posted is YOUR blog. Came up in a search randomly and just now saw it in your sig. Awesome resource! I'll be sure to follow the SCSI project if you are posting on your blog or have a thread going here.

    The writing on the back appears the be the last name and phone number of a prior owner engraved with one of those handheld electric engravers. Otherwise, it does appear to be clean and in good external condition. Thanks for the history, I did find the dobb article and usenet discussion, cool read. Also found this little summary that was helpful: https://macgui.com/usenet/?group=8&id=2072 Appreciate the tip, looks like my next step is (careful) disassembly to find the origins. Now I'll just need to find a long screwdriver to get at those fasteners deep in the handle.

    Picked up a 512k recently and saw this port on the back. This is an add on SCSI port replacing the battery slot, right? Curious if anyone can identify this hardware and who manufactured it. Assuming it includes an associated controller card. Port is metal, looks well made, and the hole is screwdriver access. Found a few other similar products, but none have this style of scsi port that is protruding from the case. Have not opened it up yet to check the board inside for markings. Anyone recognize it?

    I had the same question! After searching the forum and reading various threads, the consensus seems to be that you need a card that is a Mac version so that you can boot from it. There were a handful of different manufacturers for these but they should all specify Macintosh compatibility. Some PC cards can also be flashed with a Mac bios to work. I ended up finding one on ebay for $35 but it wasn't listed as a Mac card, but did have the correct part number in the description and a label on the board. Most of the Mac versions were going for the usual ebay buy it now ridiculous price. I'm going to install it this weekend and report back!
