Thanks.  That file was less helpful than I imagined though.  :)

https://vintageapple.org/macdrivers/nic/Ethernet_7.8.image.sea.hqx I've tried a lot of things on my Windows and Macbook Pro.  I've gotten the SEA file extracted but Stuffit expander tells me that it's a corrupt file. Thanks!

Those picoPSUs tend to be very light on the 12v amps, but I have no idea if that's a concern for an early mac like this.  I have a 160 and I want to say anything beyond 5 amps on 12v rail will require active cooling of the PSU?

I have an SE/30 that was extremely dead, battery corrosion on motherboard destroyed basically everything.  On the analog board, one of the four-pin power connectors was severely burned along with several traces, and the back of the flyback transformer was cracked/crispy-looking. All that aside...

The hard drive from the second SE/30 booted.  Mouse and keyboard I got from a IIGS system I bought works perfectly with it. Pretty happy...

Thanks, that's the kind of link I was hoping to come across.  I'm wholly ignorant of what games were available on a mac of this age, I was an MS-DOS man through-and-through.

I'm not sure how compatible mac software generally is.  Is there a good resource for identifying compact mac compatible software? Sorry for the probably basic question, but I'm new to vintage Macintosh computing..

I really don't think this is the standard Mac SE/30 rom.  The internet tells me that the SE/30 rom was 256kb in size.

Replaced all the 47uf capacitors and same behaviour, slow beeps of death.  On a hunch I pulled the RAM and swapped it aroudn a bit, and it seems that one set of simms must be bad.  The second set installed in slots 1 - 4 lets the machine boot!  Looks like the drive is dead, unsurprisingly.  Time...

I have no idea if that's what I heard.  It was EXTREMELY faint, it seemed like it was a low/high beep but impossible to tell.  More caps should be here Tuesday. 

Well that doesn't sound ominous at all. :D

Speaker is nice and loud even with the missing cap, but I don't think this is the standard Mac SE/30 boot sound?

:( I just realized that myself, reseated all the capacitors with the correct polarity but of course I'm short one now.  Think a ceramic cap could fill in temporarily?  I still have those vertical bars without C9 in place. On an electolytic cap the band indicates negative, doesn't it?  Why...

Recapped the mac, blew one of the new capacitors on first power-up. That's C9.    What do you think happened?  Could the capacitor have simple been bad?

I can BAAAARELY hear a sort of two-tone chime when I turn the system on after washing it.  It's quiet enough I had to ask my kids over to verify I wasn't imagining it.  At least that means it might still be alive!
