    Flash the raid card, to AEC-6280M from 6880M, to 6260M from 6860M

    Right you are. I hope I was posting late at night and not just having that much brain disfunction naturally.... Good luck after installing the switch block. Keep us posted. It's great to read about your progress.

    Flash the raid card, to AEC-6280M from 6880M, to 6260M from 6860M

    Good luck. Looking forward to the report. The switch is just a 2 gang DIP switch. Ought to be easy to get from Mouser or similar, but shipping will be four times as much as the switch.

    Flash the raid card, to AEC-6280M from 6880M, to 6260M from 6860M

    IIRC, they had some kind of software control for setting the RAID mode on the PC card so that the switches were not needed.

    Flash the raid card, to AEC-6280M from 6880M, to 6260M from 6860M

    Guessing and assuming Kay has the correct information, which seems likely, it looks like you would want to do the following: For ACARD chip Remove: R71 Replace: 102 on R16 and R19 Afterwards, follow Kay's flashing instructions above, **but** if you want to end up with a 6880M and not a...

    Flash the raid card, to AEC-6280M from 6880M, to 6260M from 6860M

    Ah, you probably have an 'A' version of one and a 'B' version of the other. Although Kay's posting above suggests there were already 2 versions before the 'B' came out, so there may have been 3.

    Flash the raid card, to AEC-6280M from 6880M, to 6260M from 6860M

    There used to be a web page on how to do, but it's long since down. It boils down to, set a 6880M next to a 6880 and then anywhere you see a difference in the resistors, change the 6880 to match the 6880M. Then program/flash the 6880 with the 6880M firmware. There may have been one more bit...

    Spaceward Ho!

    My first LAN parties were a bunch of us bringing over our Macs and playing Spaceward Ho. Some us were even able to run the color version. But folks kept get kicked off the game seemingly at random. Later I figured out that File Sharing only supports 8 users, so every time we hooked up the...

    Brainstorm Clone?

    I believe it. I think you've been in Japan ever since we've been communicating and I think that goes back to sometime close to 2000.

    Flash the raid card, to AEC-6280M from 6880M, to 6260M from 6860M

    You are correct. Two years later, I realize I did not read carefully enough. You were writing about converting from RAID card for Mac to non-RAID card for Mac. I was confused and thinking of card for PC to card for Mac.

    Brainstorm Clone?

    My guess is that they are capacitors. Perhaps they're driving the ROMs a little too fast and the capacitors provide that extra little bit of current when the ROMs draw extra power. Totally guessing and could be totally wrong, but a component without continuity which is nevertheless needed...

    Recreating the Mac's CUDA / EGRET microcontroller chips - can it be done?

    Should the above have read: "Then you can set the MOR byte at 0x1F00 (if it's anything different to 0x00), BTW, excellent posting. Thank you for the wonderful work.

    Reproduction RAM cards for Mac Portable

    Was the thread that covered their creation on 68Kmla.org lost? The details were covered extensively there. Techknight posted as he developed/troubleshot the cards. Edit: Okay, this point in the 68KMLA thread seems to be where the wire starts getting discussed. I'd read the whole...

    Recreating the Mac's CUDA / EGRET microcontroller chips - can it be done?

    The tricky part in finding the part is finding a '705 with enough RAM. The e1 has 368 bytes of RAM. Most of the other variants have 176 or similarly small amounts.

    Software-only OVERCLOCK for LC475, LC575, Quadra 605

    What affect will this software have on a machine which has had the 33 MHz resistor move modification? Do the resistors need to go back to their original positions? Edit: Never mind. Found the answer here...

    unknown part on 128k analog board?

    Ten years ago, my efforts to reproduce. Unfortunately, the thread where Wally reported the inductance range is long gone. I want to say 0 - 44 uH, but I don't think that's right. https://68kmla.org/bb/index.php?threads/anyone-have-a-dead-l2-adjustable-inductor.27941/#post-294686

    TwiSlot PCI Riser and ComSlot2 NIC repro in widened CS riser form factor

    Wire wrap may be alive an well, but my favored tool came from Radio Shack, and they're long gone -- I think. Haven't checked for a lingering on-line presence in a while.

    TwiSlot PCI Riser and ComSlot2 NIC repro in widened CS riser form factor

    That is my understanding as well. Except I don't think there's any need for coordination between the busses. If a PCI device wants to access RAM, e.g. and the relevant Bandit doesn't have control of the CPU bus, I assume the Bandit would just stall the transaction until it's ready to bridge...

    TwiSlot PCI Riser and ComSlot2 NIC repro in widened CS riser form factor

    Well in the thread with the 9600 schematic (and 6500 schematic) that joevt referenced above, I posted my thoughts. I concluded that you can probably just solder the chips I have in place of the existing chips, (matching pinouts) but the question is then exactly what you asked. How does the...
