Re: Mac Classic - will it ever run again!!
Good news on the classic. @Kai Robinson I believe he is working on a clasic ram board replacement Tom Indeed I'm rather pleased :) Cool, I do have a Simm board that used to work, but has decided not to :( @Kai Robinson are you building a replacement by any chance? https://tinkerdifferent.com/thread...

Ooof - a lot has happened since i last posted, for the full story, the project over at 68k MLA will fill in the gaps - but essentially, a respin was needed, after that respin - we managed to get some helpers to look over the sprint layout, as my eyes weren't picking out anything - and 5 really impor...

Re: TQFP Soldering Gods Required! (PAID WORK)
The chip covered by the CE/FCC ID sticker is the first known ARM chip used in a Mac - it handles the 040 to PPC bus translation. A lot of people would kill to have the schematics for this thing... No luck finding the IC through anyone dealing with NoS or used - not even UTSource. ppc601-apple-vlsi-a...

Re: TQFP Soldering Gods Required! (PAID WORK)
It TQFP is fine really. You can even do them without a microscope and inspect them after with a magnifier. A hoof tip on the soldering iron, good flux, a microscope and practice make it pretty easy though. On a rare card I'd cut the old chip legs to minimise risk to the PCB removing the cracked pack...

TQFP Soldering Gods Required! (PAID WORK)
So...i managed to pick up a very rare Mac accelerator - the Daystar PowerCard 601 for my Macintosh LC475 - unfortunately, the main die of the PPC601 is...well, it's cracked. like 1/3rd the way across. Dead. However, i'm seriously a little nutty and want to try and resurrect the card. The chip is a T...
