Re: not 100% accurate, I think what was meant is that power supplies can vary slightly from the factory. I believe Maccaps says on his own site that the values shown for caps in the photos can vary and that users should double check the values before doing their own replacements. If you sent the...

BTW how did you remove your capacitors? I’ve been experimenting with different methods. On the test board I used the twist method but only because this board is already too far gone to save.  Also, for the record, my yellow gunk did not respond to flux remover which I think might be a relative...

I have just been practicing cleaning a junk (damaged past hope) SE/30 board. On mine the gunk under the capacitors looks like a dot of yellow right in the center. I assumed it was capacitor leakage but maybe not? I had some success scraping away some of the gunk with a toothpick and isopropyl...

I love those videos, and the vintage quality just adds to the experience. The 1970s called, they want their high school projector back.

What is a Snooper Card? It sounds useful!

So how does this thing work exactly? You plug the relevant cartridge into the TechStep (I assume), plug the techstep into the problem machine (I’m guessing? Which port?), and then...?  Very impressive looking collection! Are you missing anything that you know of?

Huh, I had a Performa 630 bought new back when but I don’t remember having a disk by that name. My old Performa stuff is pretty scattered. If I ever come across something like that I will take note.  I have an Apple CD Software Demo disk but that doesn’t have an option to purchase codes, just a...

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. 

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...

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...

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...

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.

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...

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...

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...

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. 

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...

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...

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...

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...
