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.

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...

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...

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.

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.

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...

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.

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...

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.

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...

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

Yep, that's the one I have. I just really love having the stripper conveniently stored in the handle...

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.

I treasure my wire wrap tool, as I'm not sure I could find a replacement...

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...

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...

Okay, I looked at it. The differences are minimal. Bandit 1 has a GNT/REQ line connected to Grand Central and Bandit 2 does not. Which makes sense. You don't want to put Grand Central or any other PCI device on two different PCI busses. Pins for Bandit on Arbiter 1 are connected to...

Sorry for hijacking the thread. We now return you to the regular topic....

ClassicHasClass answered that better than I could have. Yes, it has OF. That's a little disappointing, although at this point in time, a solution for the S900 is more of a white whale than a real need. :) Still, it's very puzzling. Architecturally, the S900 is like a PM9500 with the...

I wonder if they did that so that it would be easier to use the same ROM on all those machines. If it's at F0, it's video circuitry. If it's at F4 its more PCI slots. It would be interesting to get the Mac OS running on the ANS. However, two of the PCI devices on that six "slot" Bandit...
