    • Wait, I thought you couldn’t swap orange flex cables with normal ones? Does that mean one could theoretically repair M5126 Backlit Portable display cables this way?   Kudos BTW! At least it’ll be sturdier than the original. 
    • This is really nice work.  Well done.
    • Nice work - I admire your patience resoldering that ribbon cable - any further tips, what temp did you have your iron at to get the solder to take on the copper connectors?   The PowerBook 180c is such a nice machine - all that colour, speed and (chunky) portability in the day would have been amazing.  I assume Apple didn't sell too many owing to the initial cost of ownership; the venerable PowerBook 170 would have been the professional 'book of choice more in the day.
    • Boom! Works like a champ. Clear and crisp with all colors reporting for duty.     Here's the other half of the splice with a bit of the original end below it. After stripping away the insulation, fluxing, and tinning, I landed the conductors, then covered the solder pads with a thin coat of UV activated resin (if you don't have a Bondic pen, I can't recommend them enough!)

        And finally, here's the 2nd end of the ribbon installed.

      I guess now that the real show stopper is corrected, I have to set about sorting the rest of this thing. The installed 160M drive was DOA (clunk of death), so I installed a spare 500M with 7.6 on it. for testing Between that, the LCD cable, fried memory module, leaky battery, and busted hinges, I can't help wondering if I'm resurrecting someone's parts unit

      Oh, and it's missing the trackball bezel. If someone happens to have a spare they'd part with reasonably, it'd sure beat paying the going rate for the whole assembly on eBay...
    • Don't bring the PC into this.   Nubus had a burst speed of 40MBs and 10-20MBs sustained. Nubus 90 (Quadra 840av and PPC era) did 70MBs burst and 30Mbs sustained. VLB started at 100 MBs for CPUs with a 25 MHz bus, increased to 133 MBs at 33 MHz and 160 MBs at 40 MHz, and reached 200 MBs at 50 MHz. Granted getting cards that worked at 50Mhz was not easy let alone using more then one at a time.   So while the built in video an a Quadra would have a faster frame buffer then an ISA based 486, a VLB based 486 would blow the doors off a Quadra especially if the 486 had cache which they all pretty much did.
