    Complete TechStep

    Congrats!! I would love to hear about your Apple Service adventures. It’s never been entirely clear to me how those things are supposed to work.
  2. Sweet setup! Those KVM switches are impossible to find now for macs. If you are running both computers at the same time, does the keyboard still function when hot-switched? Do you have any trouble with soft power-on? re: printers: for that era of computer a color StyleWriter would be period appropriate (I think? I never had a color one, only a regular one). The ImageWriters were dot matrix and were already obsolete when I bought my Classic. Scanning though I am not sure. I think of all in one printer-scanners as a USB era thing but I wasn’t an early adopter in that area.
  3. Yeah, the SE/30 is super fussy about what combination of RAM goes in what bank. I had that problem and had to reinstall my configuration of 64 + 4 about five different times before I hit on the right combination. The summary you attached looks like the most thorough explanation I've seen. (Oddly, it sticks in my mind that I had to do the reverse of what the usual advice recommends, put the larger size in Bank B... I documented my experience in an earlier post on these forums back in 2016. My SE/30 is finally kind of working and I'm not going to open it again to check!) The floppy drive problem is not likely to be related to the other. If thorough cleaning didn't fix the problem of disks not reading and formatting correctly, you likely do have an alignment problem. I have never successfully fixed an alignment issue but others here might be able to advise. I didn't know there was an alignment procedure described in Dead Mac Scrolls, I will have to check that out. Good luck!

    Fitting a SCSI2SD in a 68k Mac

    I just was rereading this thread and saw that you have a 128gb drive working (at first I thought you must mean 128mb). How exactly are you using that with System 7 era macs? I thought 2GB was the limit for HFS Standard. But I just recently got my SCSI2SD and am still learning. You mentioned a 700 MB HD in your earlier comment, but do you have to use the card in an HFS+ Mac first to move stuff to the 700mb drive for transport? (Most of the time 2GB is fine for macs of that era but I wanted to organize content from a bunch of early CD ROMs and those CD-ROM megabytes add up fast.) re: the PB 1400, do you have another known good SCSI device you can test it with? Alternately, have you tried applying external power?

    Macintosh Classic Ram problem

    Where do you order that type of chip from? Also, I should probably contact Uniserver - I could use a few schematics. Good to know that is still an option. I remember reading a thread about the service that was selling schematics and wasn't sure if it was still around.
  6. I have a SCSI2SD and love it. The only annoyance is not being able to write directly onto HFS volumes in Sierra. A lot of my archive is stashed on my modern Mac, and the vast majority of the vintage stuff I work with is pre-HFS+. I can mount the various HFS formatted SCSI2SD volumes in my modern Mac but they are read only. I could move some of my software archive to my OS 9 MDD, which is the only other machine I have with a hard drive big enough to handle dozens of GB. It would be nice if I could then read and write directly to the micro SD card in my OS 9 mac, which has USB but no SCSI interface. If I plug a USB SD card reader into an OS 9 mac, will the drives mount? The OS 9 mac has no trouble reading various other hard drives and flash drives with a USB interface. (My current SD card reader is a USB-C unit so I would have to spend the princely sum of $20 on a plain USB SD card reader to do this, I can't just plug one in and try it.) The MDD does have an OS X boot option, if that makes a difference, but it is buggy and I almost never use it. I can't even remember what flavor of OS X it runs - probably 10.2 or similar. One of these days I will get a G3/G4 era mac set up with both SCSI and USB but that is not this day.

    Anyone Have a Dead L2 Adjustable Inductor?

    Sorry for the thread necro, but I am wondering if any progress was ever made on this. I searched the forum for "L2" and "width coil" without much success (at least half the hits were me complaining about the destroyed width coil in my SE/30). Long story short: I now have two analog boards with destroyed width coils (an SE/30 and a Classic). The first one was my fault - too much force applied with the wrong tool, years ago - but the Classic one (which I just discovered yesterday) was crumbling before I even poked gently at it with my plastic TV alignment tool. I can fix the problem by swapping in another working analog board (already done for the SE/30, on my list today for the Classic), but I hate to see donor boards piling up in my workshop just because of these wretched width coils. Anyone had any success sourcing or manufacturing a replacement for the L2 coil?
  8. You need a SE-specific PDS card. The SE/30 card looks similar but will not work AFAIK. I don’t think the SE card works in any other machine. Example (not my auction) https://m.ebay.com/itm/Macintosh-SE-Asante-Ethernet-Card-09-00300-51-Rev-C-Mac-Con-Modem-SE-/192617275194 The floppy drive is irrelevant (unless it makes the case too crowded, I guess?). You should however check to see if your chassis has the cutout for the PDS slot. Some very early SE machines don’t have the cutout. Keep in mind that a machine as old as the SE probably won’t be able to do anything besides FTP and simple file sharing. I do like having internet for that purpose on all my machines, but I don’t currently have Ethernet on anything lower than the IIsi and the SE/30.
  9. Oh wait, now I see that you already have both functions covered. In that case, this card won’t help you. It would be more useful to someone who needed one function or both.
  10. That’s a common combination, I have a similar card in my IIsi. The most important thing it does is provide an Ethernet connection, but the FPU is handy for some applications that run better with extra number crunching ability. (Although, looking more closely at the pics, I see the slot for the FPU but it looks empty - maybe I’m looking at the wrong thing? The Ethernet would work regardless and an FPU could always be added later.)
  11. Good news, glad it worked! Since you have the A ROMs, keep an eye out for unexplained weirdness. My incompatible floppy drive seemed to work at first but then started throwing a host of inexplicable errors. Hopefully you won’t have that problem. I wonder if Apple found it easier to just update the ROMs than to track down which floppy drive (parts) worked and which didn’t. Fun fact, the OA-D34V seems to be exactly the same as the floppy drive used in the Lisa, except the Lisa drive has stubby little feet on the bottom.
  12. What are the version numbers on your ROM chips? Do the numbers end in A or B? If A, the simplest fix is to swap the ROMs to a B version. They are available on eBay (off and on) for about $60-80. If B, I wonder if the logic boards on the two types of Sony drives may not be fully compatible. Assuming you have B ROMS, maybe you should try installing the 22 drive as an intact unit as shipped. The documentation out on the web makes a big deal about the square sticker, but I am working on a project experimenting with a bunch of non working 22 drives and one with no suffix (OA-D34V), and the differences between the no suffix drive and the 22 are substantial, while the square and round stickers show up on both drives. Where the 02 fits in the sequence I am not sure although it certainly seems closer to the 22. I’m planning a post on this soon.

    Need guidance on Classic II repair

    Definitely adjust it, but then check the 12V supply as well, if that is applicable to the Classic II (I know it works on the earlier compacts). If you can't adjust to 5V without throwing 12V out of whack, something is wrong on the component level. From what I gather a voltage reading that far off is not uncommon. Hope a simple adjustment fixes it for you!

    Need guidance on Classic II repair

    That is one of the most well worn tool kits in my arsenal! (Mostly used on Plus and under machines, for me.)

    PB145B’s finds

    Sweet find! I love the cheap-as-free tag sale scores. They are so much rarer than they used to be. That one is in very pretty shape too.
