Ah, got it! Sorry I may have misunderstood. You are in no danger to reflash firmware files. Even if it's not 100% compatible, I haven't harmed any of my decides by flashing "incorrect" firmware to it. I simply re-try another. Since at least your device has worked with one of them before, there...

Hi Federico, thanks for posting. As explained in a recent post above, the serial number lookup tool I made was sourced from the data on Kodak's (now offline as of mid-2024) firmware update website. It's quite simple in it's function. Similar to the Kodak site, it contained a long, long list of...

Thanks for the feedback. The firmware lookup took is based on the principal of the now offline Kodak firmware update site. It used serial numbers to determine which model the firmware should work. However, Kodak removed this website, so a lot of guesswork is involved for units beyond the serial...

I was shocked it was just the cable, I had a gut feeling the drive was okay, but this finally proved it! 😅 The software has no ability to park the heads it seems (at least from what I see in the menus). The drive appears to retract the heads away from the drive as part of the power down...

It freakin' WORKS! :p Woo-hoo!🎉 Huge thanks to @snuci for sharing the cable pinout. I created my own crude cable, and inserted the MacDrive 2.3 boot floppy... and my Macintosh 512K booted from the floppy, and then accessed the hard drive! I was able to successfully backup the entire drive. Only...

Awesome! My ROM appears to be newer (1.7 instead of 1.2). I think the RAM is used for the print spooling feature too. I've attache both of my ROMs, one was on the "power" board (with the M68008) and the other on the "data" board with the Z80. They're attached to this post. Also, I'll be...

THANK YOU @snuci for your reply and sharing your knowledge! 🎉 If you need any help with the power supply, I'm happy to take photos of mine. Mine has two RIFA caps inside, and I was able to replace them with the same type and value I used in a Mac 128/512/Plus analog board. I was super curious...

The thought is, that this board converts the drive to SASI/SCSI (at some point), the pinout of the 50-pin cable seems to confirm that. So that's one avenue to explore. At least nothing exploded... 😅 The good news is the drive head is moving! If I manually move the head a bit out of the parked...

I’m assuming the drive was used at some point in time - and hoping there’s data on it. I’m mainly curious to see what goodies are on it versus using the blasted thing as a new drive, but I guess that can be plan B. 😅 Since one of the boards seems to be connected via SASI/SCSI, I’m going to...

Correct, sorry for not stating that above. So currently, I get the same error if 1) the drive is plugged in and turned on with a straight serial cable connected to the modem port. 2) the same (but with the HD removed from the case), or 3) with nothing plugged into any serial port. I'm also...

Well, with the HD removed from the enclosure, but everything else plugged in, I get the same error about the drive not being recognized. I reseated a bunch of chips (but not all) and cleaned a lot of the edge connectors. The drive spins up, but I don’t see any head movement… maybe the sensor...

I only took a quick peek, but it looked like copper, similar to this "clock" someone made and posted on eBay of the same model drive. :oops:

Thanks David, I'm currently performing a number of those steps today. I didn't think of testing the enclosure without the drive connected, that's a good idea. I'll do that. (y) I'll report back and keep everyone posted. Here are some more photos of the boards... featuring a Z80 and a 68000...

Out of curiosity, I opened up the Tecmar "Volume Manager" software (v6.0.3) in ResEdit and looked through the alert messages. This is the message I'm seeing when I use the drive. It's kind of vague, but I'm assuming it means it can't find or detect the hardware. These are some other...

The Hyperdrive one is neat! And yes, this is a bigggg drive. Thankfully the MacGUI article I linked to above (after you log in) has THREE versions of the Tecmar software, one of the later ones should even work with System 6. Sadly, as I mentioned above, the software simply says it doesn't...

Yep! They had to use volume shenanigans to get around the maximum storage sizes of the original system software, hah! This MacGUI article states: "You can partition your MacDrive in up to 20 volumes. Of these 20 volumes, you can mount two at a time on the Macintosh 128K, or four at a time on...

That's a good question! This drive I believe was also capable of working with the Mac 128K, where the HD20 needed the 512K to work. One of the original BlueSCSI System images I booted from had that driver, but it didn't seem to do anything. From what I've read, this uses a special driver which...

Hey all, I wanted to share something neat I picked up at VCF Midwest this year, a Tecmar Mac Drive, perhaps the first external hard drive for the Macintosh. This drive uses a serial port to connect to the Mac, and some software shenanigans to get around the storage size limitations of the...

The camera sensor? I haven't seen a source, it may be a custom part, but it also may be similar enough to find a replacement. The pinout of the ribbon cable to the camera isn't known however.

This may help, @Ron's Computer Videos did a great video and journey of archiving a lot of Adaptec drivers, including the 29160, you can check it out here: https://macintoshgarden.org/apps/adaptec-powerdomain-scsi-card-firmware It looks like it may have something similar to what you need. Note...
