Allows the 33MHz 68040 I got from @k24a1 to run at its full speed, instead of at 25MHz. The resistor at R151 is removed and a resistor is added at R152 on the bottom of the board.

Likewise. I've owned pretty much everything I ever dreamed of owning when I was younger. Settled on a SE dual FDHD (er, SuperDrive) for my 68000 desires, a IIci for my '030 needs, a Centris 650 (that will eventually become a Quadra 650 once a resistor is removed and a different resistor is...

I'd see if I could find a SCSI cable from an 8600 or a 9600 that's being parted out... It'll have a lot of connectors on it, but it'll be more reliable, IMO. I bought one for my B&W G3 from a used computer reseller (RE-PC in the Seattle area). Am using it with an Adaptec 29160N SCSI card...

Another thing, if you move the AB to LB harness at all, does it restart? The harness in my SE has some wires that look to be damaged. If I move it into a certain position, sometimes it'll just stop, either freezing, displaying a checkerboard, or nothing at all. Normally that would be a sign...

^Should be about two minutes. My IIci takes about a minute and 48 seconds to show video.

If I remember correctly, most iMacs used the 3.5" SATA drives, so, you can run anything that a pre-2013 Mac Pro uses. Back in 2020, I bought a 1TB spinner for my 2008 Mac Pro for ~$35. Is the one item I still have from that computer. Will be going into the 2009 Mac Pro 4,1 I'm picking up next...

Here ya go. https://www.ebay.com/itm/124388415055 @Scott bought some for his SE/30 as well. Seller is based out of Pennsylvania.

I got the SIMMs I used to upgrade my IIci to 128MB off the 'bay. Cost was around $80, plus shipping, and the dreaded sales tax. Brand new memory.

Disk Tools 1: https://macintoshgarden.org/sites/macintoshgarden.org/files/apps/DiskTools-753-patched.sit Save to a Mac that can access a floppy drive (USB or built-in), then write it to a floppy.

We have the same faucet here at our place. Just a heads up about it... Sometimes, it will dribble out the spray holes, instead of just using the aerator. If I depress on the switch that goes between the two modes, it will usually stop dribbling for a bit. Sometimes helps to also depress the...

Yup, pretty much. Just have to add the slot for the SIMM, then program one and drop it in. -J

You can add a ROM SIMM slot, then use what I was recommending. The solder pads are there.

They work pretty well. Eject motor is a little louder than it normally would be, but, at ieast the disks eject properly again. Installed one in my Centris 650's floppy drive's eject motor assembly.

^It should work. Not sure which chips you'd need, though. If the ROM SIMM socket is installed, you could get away with one of @dougg3's SIMMs, programmed with the ROM dump files you found.

Looks like Eric has a M3501 (the AEK II), just doesn't have it pictured. Instead, his M0115 is shown.

No problem. @Paolo B was the person who clued me in on it... In this post: https://tinkerdifferent.com/threads/superdrive-floppy-maintenance.549/post-5174

Nice setup. I haven't gone there yet. For a while, had a Mac/Apple II closet, back when I had the 2012 conquest, but am now down to a closet shelf where my C650 is currently residing, while it waits for a replacement eject motor for its floppy drive, and the Mac table, which is where my...

That does sound like the ZTS isn't lined up correctly. I would crack the case open again, take the drive out of its bracket, then place it on something that's not metal, so it doesn't provide a dead short when the power switch is on. While the computer is powered up, loosen the screw for the...

Yes, you may have to. All three of my Macs needed to have the adjustment taken care of, even though the sensor was never moved by someone prior to my servicing the drives. The eject problem, might be a board issue - I do have one drive in an A9M0106 external case that will not operate an...

This may also be somewhat pertinent after the drive is assembled again. https://tinkerdifferent.com/threads/superdrive-floppy-maintenance.549/ Might need to adjust the zero track sensor as well, as described in the above thread.
