Ha ha I just did the same thing!

@max1zzz Much appreciated! It makes a lot more sense for this to move to a marketplace forum—especially since I put WTB in the title. Sorry about that. Still, a little troubleshooting confirmation was worth it here. I am in Portland, OR, but I have not started shopping for EPROMs. I was merely...

Good to know I have not been missing a source of these. I suspect anyone reading this who has a spare Classic ROM from a parts LB or battery-bombed unit probably wants to keep theirs which I totally understand. I have a buddy in town with a EEPROM burner. I need to reach out. Also, the recent...

Ok, I tried uploading the .dmg file. I figured I could add the boot.efi as an additional like other collections I see on the garden site. Anyway, it it stalls at starting upload. . . with no sign of progress, so I am going to let it sit there a while and come back later to see if it finishes or...

I wasn’t sure about policy and ownership etc. on the garden. I could have upped it there I guess. That zip file I made also has the boot.efi. I don’t really remember how it was used at the time, but I remember it was important.

@scj312 this should probably go somewhere better, but for now you can get that old image here: https://mega.nz/file/1IxTBaKb#ULBYM7QASeFBklMPCqJDQk9p24oL4cKAPvE3Mog-WXo

I am restoring a Mac Classic. Recapped the logic board, fixed a trace or two. Washed everything thoroughly, so no more residue. Overall, the board looks pretty clean now. However, a boot test results in clean, unwavering black and white checkerboard. 5v and 12v power tests fine, CRT is nice and...

@scj312 For what it’s worth, I have the ATVOSX.dmg file that was “lost to time”. I was following along with my ATV 1st gen back when this was under development, running AwkwardTV jailbreaks and such. . . This was a lot of fun! If that original tiger disk image alongside the boot.efi file that...

Thanks for confirming. It definitely opens more options when considering different offers.

In my case, I had already removed the ASC, cleaned it up, put it back (a little crooked) and then I started having SCSI issues. I had not recapped the AB or PSU yet, so as I was moving from issue to issue it felt like problems were evolving so while I might fix one thing, something else would...

I totally get the “lost cause” feeling. I actually put my SE30 on the shelf for 9 months in frustration before I found the broken data line, which was actually easier in the long run than how I was feeling about it at the time. Progress was slow to uncover multiple overlapping issues, but I had...

I had distorted sound and bus errors on my SE/30. It is cleared up after the following: Removed, cleaned, resoldered ASC Found broken trace for D31 between SCSI chip and CPU. Bodged and that fixed sound distortion Recapped analog board and PSU which cleared up bus error on shutdown. There are...

Follow up question: Parity vs. Non-parity. . . I am seeing Parity, 9-chip SIMMs that are cheaper than those only populated with 8. Can I use these in compact macs? Or do they have to be non-parity? And what’s with the warning I have seen written about avoiding composite RAM?

Wow. Ok. Mind blown. I should not be surprised by this at all, but I am. However, this makes a lot of sense given how simple these little boards actually are. I am tempted to try this just for the sake of being able to, and with only two chips per 1MB stick, the soldering from new chips would...

The retro-computing hobby, especially as it applies to compact Macs is as much about troubleshooting and repair as it is about using these systems. For many of us, the experience or journey to a successful restoration is the reward. With that in mind, an important troubleshooting step (and part...

Yeah, finding a continuity issue—it is always the last one you check! ha ha ha

My SE30 had multiple issues—one of them being distorted sound, and occasional crashing when testing alerts in the Sound control panel. I removed the ASC to clean underneath and glad I did. The crashing stopped, but some distortion remained—not evident in the startup chime, at least that I could...

There is a delay if powered internally, but it works. The issue with internal, however, is shutdown. Development updates are being worked out that will clear the drive cache if idle for a few seconds—without which, currently, if you initiate a shutdown and when prompted by MacOS to turn off...

I appreciate your perspective here, as I imagine all of us were in a very similar headspace the first time touching CRTs. I am more worried about my hand slipping and breaking the neck than anything. SO, the BEST way, so I have read, to discharge is to connect an appropriate/correct (big)...
