Over years of swap meets and hamfests I've accumulated a pile of slotted processor upgrades for G3 era Macs. Unfortunately I do not have any system that uses this form factor and I don't know what their operational status might be. Is there anyone on this forum that lives in the US and might...

I can't tell from the available diagrams, but some video displays powered the CRT filament from a winding on the flyback transformer. If that's the case with the SE/30 then missing H-Sync from the motherboard would result in the symptoms you describe.

I had it on 3 of 4. Everything cleared fine except for that one pin. I'm just happy that the system worked afterwards!

I finally screwed up my courage and took the Hakko to my SE/30 motherboard. Everything went reasonably well, but there was one stinker pin that I couldn't clear - tried everything to no avail. I wiggled it with a pair of needlenose pliers and the chip came loose, taking the via barrel with it...

I'm not sure what you mean by configuration file, but here are a couple of tarballs for you. The 486 is prebuilt for Intel linux (32-bit). The other is source code that should build on any modern platform if the "usual" build tools are in place (e.g. make, C-compiler). All I did was start...

I believe that you simply need rpc.pcnfsd running on the NFS server. It hasn't been part of any Linux distro for over 20 years, but source is still out there. I built it today and after starting it (as root) on the server I was able to authenticate using NFS/Share. However, on OS 8.1 it...

I solved my problem (failure of Daynaport SCSI to automatically reconnect remote volumes at restart) by moving up to OS 8.1. If you enable 'Modem Manager' in that environment the system properly registers on the Appletalk network during boot and, lo and behold, the remote volumes appear with...

I picked up (12) LR50 batteries for $19 + shipping: https://www.ebay.com/itm/183896438564

Sure, here 'tis:

I had originally planned to put heatshrink tubing around three LR50 cells, but simply stacking them in the Mac / MacPlus battery compartment works fine. The contact pressure holds everything together.

Hakko recommends 3-4 as proper settings for a multi-layer board with power planes. I'm going to use the preheater and bring it to 100C before applying the FR-301. Belt + suspenders! Keeping my fingers crossed :)

Thanks for the tip! Maybe it's just me, but I've found Phoenix Connectors a huge PITA to deal with. High shipping charges and very slow to get things out the door. I was able to find a couple of NOS sockets on eBay and hopefully they are as advertised.

I had already thought about the pins, and definitely would not plug that chip into a socket afterwards. Here's a couple of photos of the Dove board:

I have a hot air station (Global Specialties Blackjack) so I can certainly try that.

I admit I never tried to install from those disks, but the title sure sounded promising.

That's very good to hear! Do you recall the diameter of the nozzle you used? Heat setting? What concerns me the most is that sometimes you get a real stubborn pin that refuses to clear. With a chip or a socket I generally grab on with a pair of long nose pliers and wiggle the pin to break it...

I found this in my archives. Please let us know if it works for you?

I have acquired a Dove Marathon 030X/SE accelerator board. Apparently it's compatible with the SE/30, but expects to plug into the CPU socket. The SE/30 CPU is unfortunately soldered in place. What do folks think about my chances of removing the original CPU without damage to the board? I do...

That makes great sense for almost everything. But, the Mac 128, 512ke and Plus have a battery compartment on the back intended for a 4.5V battery that's long unobtanium. Stacking 3 LR50 cells gives you the right voltage and fits perfectly in the existing holder. But for anything with an...

The (expensive) Excell replacement batteries are actually (3) LR50 cells spot-welded in series. I haven't tried it yet, but I bet three individual LR50s with heat shrink around them will work just as well. The combination is a wee bit longer than the OEM battery so tension should hold...
