    180MHz 603ev CPU upgrade for 5300ce?

    As I do more digging into these machines, I am pretty sure that the 5300 Series would additionally be firmware limited to a 4x multiplier – so 133MHz max on the 33MHz bus.

    Daniël's PowerPC BGA chip swaps

    So it's a XC9536 In-System Programmable CPLD on these 603e upgrade cards. I'm guessing there's no way to get the bitstream off that, due to protections.

    IIsi RAM-Muncher INIT - but for System 6

    Just turn up the disk cache to 768k, if this is possible.

    Daniël's PowerPC BGA chip swaps

    Think I figured it out. That Xilinx chip (CPLD or FPGA) is there to enable multipliers above 4x to work, i.e. to be to use a processor at above 133MHz. It’s the only reason I can think of why the 100 and 117 PPC cards don’t have this but the 167 and 183 do. The PowerBook 1400 Series has the...

    Radeon 9000 Pro AGP Flashing

    They do… both @Phipli and I noticed ‘shimmering’ (like a sort of noise) on our Radeon 7000 PCI cards’ display output, that recapping fixed. I’d be surprised if bad caps caused something like the extreme corruption I’m seeing on my R9000, though.

    Radeon 9000 Pro AGP Flashing

    The seller was nice – they refunded it and let me keep the card. Screenshots attached. I wonder if it's more likely VRAM or the GPU.

    Radeon 9000 Pro AGP Flashing

    I put the card back in my PC and restored the original BIOS - the same corruption is there, works fine at cold boot - symptoms appear after 20 mins and get progressively worse. So it’s just a dud card.

    Radeon 9000 Pro AGP Flashing

    The ROM I’ve used sets the VRAM to 250MHz, and the VRAM is rated at 3.6ns/275MHz. So it’s already clocked conservatively. Don’t you think it’s more likely that one of the chips is bad?

    PowerBook G4 12” Battery Re-cell possible?

    Rebuild done, will find out soon if successful.

    Radeon 9000 Pro AGP Flashing

    So after my card warms up it starts to artifact as well - a sort of fine texture of yellow and blue dots over the whole screen. Very odd.

    Micron Xceed SE/306-48 and SE/30 issue

    I've been tinkering with the card a little more now that I've got my M1297 recapped and reassembled. It's actually misbehaving in both my Apple and Reloaded boards. I could not get it to work initially but after reseating it and power cycling it several times, it finally started working. Really...

    Radeon 9000 Pro AGP Flashing

    I’ve just flashed a PC Radeon 9000 (Pro?) 64MB AGP with the 136 ROM and it works fine. On my first attempt I got a screen full of garbage too. My card looks the same as yours except that it has a switch populated at SW1 next to the VGA connector. I see your card has the pads, but no switch...

    @Phipli I hear you regarding the cost of … everything. My symptoms were that the computer’s front light would light up momentarily when pressed and then nothing. A few of the caps were noticeably bulged. I replaced everything apart from the three large bulk caps and it sprang right to life after...

    MDD Cache speed

    After installation it freezes on extension load, after ‘testing caches’.

    No Sound Se/30 Reloaded board

    Yes they are - they’re just there for testing purposes in case you want to test the onboard sound without a headphone jack installed.

    Durosity’s conquests and collection

    What PSU does the Quadra 800 use? The motherboard connector for Q800 is the older IIcx style 10-pin. 840AV and 8100 use 22-pin. But the PSU has a detachable harness so maybe it just uses the same PSU with a different harness. Edit: found a pic of the Q800 harness:

    LC475 with no video

    I was. I got confused and thought someone was trying to disable the onboard ROM but see now they were talking about RAM.
