Just gotta get around to buying that Dual 1.25GHz MDD FW400 for this new set of MDDs . . .

. . . one day! :approve:

p.s. I'll be using a Zip250 behind 'em. }

Very interesting - I never knew there was a Zip option for the MDD! And I see that it comes with a new bezel that replaces one of the doors with a Zip slot. Interesting.

Holy Unobtainium, Batman!

LCGuy, it's not well known because it is not an Apple upgrade. That also makes it really hard to find, let alone in the box.

JT, grats. Do you need any 750 Disks? I have one pack, but would be willing to let go of a couple.

 

[Trash80toHP_Mini]

Thanks, jr, just one would be nice to have. I don't really intend to use the drive, I'm sticking to the 250s. ISTR something about Zip100 incompatibilities?

You were the one who clued me in to this rarity in the "I wanna QS Zip bezel" thread.

 

[jruschme]

Good move staying with the 250s. As I understand it, the 750s can read/write 250s, but only read 100s. PM me your address and I'll pop a 750 in the mail.

 

[Trash80toHP_Mini]

I'll do so, but take your time, it'll be a while before I even have time to open that box, it's 1400 fun time.

NOT A RECOMMENDATION!

I thought I'd made another major Zip conquest a while back. I picked up a pair of internal SCSI ZIP 250 drives, but they haven't worked out very well yet. :-/

I picked up a pair for $100 shipped with high hopes and the drives work fine up until the it's time to dismount/eject the disk. I've only tried them with iomega guest on a few different OS versions and once on a system with a driver install so far, so there's still some hope.

Pretty cool find nonetheless, might work out as a 250MB boot drive for compacts. Less power and heat than adapted SCA drives I would think. I haven't bothered to try it out yet, but they may fit underneath the FDD in a Compact. I'm pretty sure you'd need to do a nasty power switch shutdown method due to the dismounting problems, but it might work out. If someone wants to do some serious research on them for this purpose and for the driver issues, I'll gladly loan one out.

Do you mean that they automatically eject when you shut down?

If so, I have a fix: format the disk using Apple HD SC Setup (the patched 7.3.5 version). Then the machine will think it's a regular hard disk, and it WON'T eject it at shutdown/restart!

It works wonderfully with 100MB disks (it's MUCH more compatible, too); not sure about the 250's, though. I'd imagine they'd be similar.

[Trash80toHP_Mini]

Nope, they won't dismount/eject when you try to remove them. I haven't tried to boot and shut down from one like you would for a Mac Plus installation. I'm guessing it'd probably bomb without ejecting the disk at the shutdown command, hence, the flick of the power switch shutdown. That's gotta be safer than AutoBombing the system, but I'm pretty sure the disk would stay put in that case as well.

 

[CC_333]

Well, the way I have them configured, the drive won't eject the disk if I simply choose Eject from the Finder, but I can press the eject button on the drive after doing so, and it'll come out just fine. You're saying your drives don't physically eject the disks? It sounds like a mechanical problem in the eject mechanism then.

c

 

[Trash80toHP_Mini]

Nope. it's drivers, if a Zip disk is mounted on the Mac desktop, hitting the eject button doesn't do anything on any Zip drive I've ever used, IIRC. It's one of those nasty data protection/desktop rebuilding prevention schemes. The eject button only works when a Zip disk won't mount on the desktop, in my experience anyway . . .

. . . be that as it may!

The MDD Zip 750 arrived today!

It appears to be NIB! [] ]'> I haven't looked at the drive itself yet, but everything else is sealed up as it shipped, The only scratch protection film that's been diisturbed was a pair of little tabs that kept the CD Door closed.

I'm tempted to buy a set of those clear handles on eBay and build a Clear Plexi MicroMDD HoaxMac! }

Waaaayyyy too many hacks & toys and soooooo little time. :-/

If I drag the zip disk to the trash it ejects.

 

[Trash80toHP_Mini]

Yep, if the drive is compatible with the drivers, that's how it works.

What you guys are missing is that these are IDE Zip 250 internals with an application specific IDE<->SCSI2 bridge conversion card & carrier that's set up for a standard 1/2 height 5.25" drive bay.

These drives will mount a Zip250 on a Mac with a SCSI bus using iOMEGA guest, but they won't dismount the disk with the Command-Y shortcut, by dragging the disk to the trash or by shutting the Mac down in any OS/driver or iOMEGA Guest config I've tested thus far. Hence, the offer to loan one out for serious testng across the 128k->NuBus PPC spectrum of Macs and attendant OS/Driver combinations.
