yeah, I got that, it was meant "In the meanwhile I put it under the sunlight". The heat gun did not work for me, maybe the solder mark has a different chemistry

I've added all the previously broken traces, to the best of my ability. The Address and Data lines have been fixed, along with the RCMUX, GND, VCC, and all the resistor lines associated with the RAM multiplexers, plus RAAF and RABF lines to the RAM SIMMs. The PDS lines are not yet connected; I...

I'll try, tks, today I put it under the sunlight... I can dry all of it in a batch :)

The baby is with me now. I haven’t opened it yet, as I’m already working on the SE/30 project. The CRT is functioning, but I’m wondering—should I service it by inspecting and, if necessary, replacing the capacitors?

Data and address lines are all set now... what a mess! I managed to avoid four bodges by restoring contact from two vias to the trace. The acid had eroded the surface of the vias, breaking the connection with the trace, it went almost unnoticed. Using solder paste and quality flux, I was able...

have a look here, it's helping me https://github.com/mishimasensei/macse30mlb/blob/master/hardware/pcb/mlb/output/Individual%20Pages/Macintosh%20SE_30%20Schematic%2010%20of%2009%20Tables.pdf I realize now it's not useful :D .. sorry

respect!

UJ2 is now in place, and all connections are routed as intended. Creating the pads and traces for UJ2 was particularly challenging for me. The MUX is slightly crooked, which is a bit painful to look at, but there’s continuity and no shorts, so I’m satisfied. I didn’t think I’d manage to get...

I got this very nice Apple IIc, finally! I was looking forward for the whole set!! The pic was taken by the owner, so it's not in my "cave" yet. About the checkboard ... what should I expect? Anything already known? I searched for "checkboard" in this forum but got nothing

I fully trust you mate

I love the cello scores! They are capacitors, are they? :D

@obsolete thanks, I was not aware of the latest version. @SECoyote. I ordered the PBCs and the parts ... + #2 68030 from eBay (Poland). I need the GALs programmer as well ... and get some experience with it .... I'll keep posted about the progress... it will take a while ... too many things in...

from https://tinkerdifferent.com/resources/sad-mac-error-codes.82/ it is "The Data Bus test failed. The Z field indicated the bad bit(s) as a 32-bit mask for bits 0-31, either a bad SIMM or a data bus failure." But you might have an issue with the video as well. Inspect the logic and the...

You did not tell if you (or someone else) ever recapped the motherboard and the PSU. This is the first step when restoring a Mac from the 80s. Is there any trace of leakges from the caps? A picture of the motherboard would also be useful.

thanks @obsolete , very kind of you. Did you use the https://github.com/DavidGriffith/minipro-fork to program the GALS or did you go for the Windows one?

I want to build the Performer-SE-PL-CL accelerator. Since some of the members here already built it, I am wondering if there is a list of components shared in Digikey or Mouser. A compatible Excel file to readily also'd works thanks

I soldered 3 new MUXes at UI2, UJ4 and UJ3. UJ2 will be challenging, I'm waiting for the Spot Soldering Pad to re-create the pads. I have made a "map" to keep track of the fixes required. I have not done the same for the data lines, they are in the area because of the ROM SIMM, I noticed the D0...

this might help (I did not do it) it uses a different technique, but it's a nice document and well explained

the heads of your disk drives have different alignments with respect the track 0. I'd try to make cross-tests and see which Macs, assuming you have more than one, can properly see the same floppy. Maybe only one has a non-standard alignment. Or you can find an original floppy or a known working...
