Whats with blanking out the part numbers on the chips? Have you found a super secret source of 16mx4 DRAM chips no one else knows about :ROFLMAO:

Haha :) Funny thing is I actually started with a electric griddle as my first preheater! On a more serious note, the T-8280 (originally made by Puhui, but cheaper clones are now available) is very popular amongst hobbyists, I have one and it preforms very well

The board layout, Gerbers, Copper layout and board scans are now available! https://github.com/max234252/Macintosh_LCIII-Reloaded As with the LCI board this is provided under a non-commercial license however if you provide repair services and want to provide these boards (Or want to use them...

It's easy to fall into this trap, the main reason there are less horror stories is probably just because they are newer :) I have two Apple Tanzina boards out of a couple of clones on my desk ATM and both had batteries leak, Lots or rotted traces on both, both had a bunch of bad data buffers...

Nicely done :) I still have my old Atten 858D+ (The original station those are all clones of) and use it daily, I actually prefer to use it over my ~£550 Hakko station it heats up so much more quickly and 99% of the time 700W is ample (Also it is ~10 years old and is still on it's original...

That's a hole lotta multicolour spaghetti......

That's one option, In fact one of the 3 repro boards I built up had a ceramic's installed for all the 47uf's and it works just fine :)

I'm mixed on this, Given they have been installed 'the wrong way round' from factory for 30 years and it hasn't caused a issue I'm kind of tempted to say leave them the way apple installed them, but on the other hand I do remember seeing a well known member of 68kmla saying he had seen tants...

Any luck with that one? (I'm almost ready to send the IIcx boards to JLC and might have mangled the old socket getting it out to board....)

Macintosh LC Schematics, Reverse engineered from my reproduction board layout

It's time for another one! The LC II went much quicker than expected so it's time to start on a board I have been looking at for a while - the IIcx The IIcx in question was actually purchased as a repair project until I noticed the board had layer marks, and to my surprise it was a 4 layer...

I have had no luck sourcing them before, but do let me know if you manage to find somewhere with some!

No, the GPU's themselves go bad on the 2011's, there are a few fixes that disable the dGPU on them (e.g: https://realmacmods.com/macbook-2011-radeon-gpu-disable/) it theory you can replace the dGPU but good luck finding a genuine supplier of the chip, most available are rebadged pulls I'll drop...

Bad solder joints on U8900 are a common source of intermittent video issues on there The way I diagnose this (your mileage may vary) is to tap fairly hard on the board around the CPU with the unit running (U8900 is on the other side of the board in this area) if this causes you to loose video...

Anyone know the part number for the PGA-128 socket for the 68030? I may be in need of a few some day soon.... Edit: I'll add that I know peconnectors stocks them, but as they don't ship to the UK i'm looking to see if I can source them in the EU/UK

Wonder what could be going on here......

The board has now been fully tested, everything on it works with no issues! Now that's how I like my V1.0 boards :)
