ALERT: eBay Auction, Hyperdrive 512k in Disguise!

Ah gotcha. I figured that was what you might be pointing to. But I guess that sticker is useless without the HyperDrive though...

Well it could be there. The Hyperdrive was an internal disk drive, so it's probably hidden inside the machine itself.

Yeah, that's what all the hype :) over the hyperdrive is about! It's an internal hdd for

the 512k.

I believe JDW has one.

Check the flickr 68kmla group you'll find it. Or

just search hyperdrive on here.

I'm not buying it so feel free to bid!

Weren't HyperDrive labels red text? I'd bet that is a dealer's sticker. I can't make out what the label on the auctioned Mac says. It's likely that if there was once a HyperDrive in this Mac it's been removed. On average a Hyperdrive ran for about 2 weeks between trips back to General Computing for repair, and this does say the machine works, which would be extremely unlikely at this age if there were an old drive installed. Only one way to know, of course; buy the thing. :)

[edit] Ya know, what that looks like is an original "Macintosh" sticker from the back of an early 128K. Maybe this was upgraded to 512, in which case you got a new "Macintosh 512K" sticker for the back, and the owner stuck the old label on the front.

I think that's exactly what it is. Here's a link to the HyperDrive label.

The Macintosh Logo is a STICKER?

My 512k's sticker seems to be plastic.

Well... I guess nothing to see here... :b&w:

I second H3NRY's thoughts...that sticker definitely looks like it says, "Macintosh" for me, and looks exactly the same as said sticker on the back of my M0001.

That's a "Macintosh" sticker on the face of that Mac in the EBAY auction. You can see how the right side of it is reflecting in the sun. The real question at this point is, WHY put that sticker on the front of the Mac? Seems odd to me, but certainly nothing that leads me to believe there is a HyperDrive inside.

My 512k with internal 20MB Hyperdrive also had a sticker on the face of the Mac, but the sticker was old, cracked and falling apart so I removed and placed it into File-13. Thankfully, the Mac wasn't yellowed hardly at all so you now cannot tell there ever was a sticker there. But I remember the sticker well, it was not the flat kind of sticker as shown in that HyperDrive 2000 photo, nor was it exactly like the other sticker you link two (with red it in). My HyperDrive sticker was about the same dimensions as the HyperDrive 2000 photo sticker, but mine was not perfectly flat. It was -- how can I describe it -- like it was encased in a transparent plastic "bubble" or "dome" of sorts. You know the kind, they leap out at you. My HyperDrive Mac also didn't have any special sticker on the back of the Mac either.

Even so, with EBAY you never really know what you are going to get. Who knows what is lurking inside that old Mac. And in many cases, if the sellers knew, they would try to charge a lot more.

JDW, is your Hyperdrive in running condition? If your Hyperdrive has an MMI or Miniscribe drive, it would be a miracle if it still spins. ;) NEC 20 MB drives are the best bets of those early 3.5" drives. I have a couple of old NEC MFM drives from that era which still ran last time I fired them up.

Somewhere out in the barn is a MicahDrive chassis, which was a SCSI internal HD for 512s. Micah worked out an internal drive which didn't involve drilling holes in the Mac chassis, and held the drive, controller, power supply and fan all in one piece. Pretty good shock mounting, too. The drive still worked after PanAm dropped my Mac hard enough to break the case on a flight from Paris. I'll dig it out and take pictures.

I simplified my own internal HD some years ago when 2.5" notebook drives became available. I yanked the MicahDrive and stuck the laptop drive to the top of the floppy with bits of foam tape. My Mac still boots with the Micah icon, tho. :p

The doctor is still out on whether my Hyperdrive is a "miracle" or not, but the fact is my 20MB drive mechanism does spin and read and write just fine.

Because no one has ever given me a clear idea as to the drive mechanism used in my Hyperdrive (exactly the same as one owned by TheNixer), I am curious to hear further evidence presented on the matter. Before doing so though, please be sure to read through this detailed threads on the matter:

viewtopic.php?p=6045#p6045

And here is another interesting historical thread pertaining to the Hyperdrive but not to the drive mechanism itself:

viewtopic.php?p=57472#p57472

And here are 3 of my Hyperdrive photos that show the front and back of the drive mechanism (click All Sizes to get a bigger view):










Thanks.

Yep! That's an MMI drive. You are lucky you got one that was made just right. A lot of them had trouble with excess lubricant on the disk surface spinning to the outside edge where the heads would get stuck in it. Back then it seemed like all disk drive mfrs would go through periods where they couldn't build a drive that would run for more than 6 weeks. A working Hyperdrive is a real rarity. In the day, they marked the serious (and wealthy) Mac user. The thread about how GC got control of the system to patch disk I/O at boot time is correct. Hyperdrives have PC/AT MFM controller chips interfaced to the 68000 data & address buss on the clip-on card. No DMA, if I recall, but still way faster than a floppy or an HD20.

As time passes, it gets harder to find running examples of old drives. I thought I'd pick up a spare SCSI laptop drive last time I was at Goodwill (Austin's local computer recycler), but they said they hadn't seen one for a couple of years. You have to grab spares while things are available. Right now, it's G4s that are being recycled. G3s are getting scarce, though they were everywhere last year. If you need a G3 for parts, grab one while they're available and cheap. 68Ks are seldom seen now, and collectors are starting to bid the price up.

That's an MMI drive.
Could you provide a source for your info, or a link to a photo of an official "MMi" drive? I ask this because someone from GCC told me here that it is NOT an MMi drive insofar as MMi was not a drive manufacturer.

Thank you.

I don't think that's a Hyperdrive 512k but if it is the Hyperdrive is probably still in there - it'd be way more effort to remove one than to leave it in. I have a Plus with a Hyperdrive 2000 that still spins and a 512k with a Hyperdrive. I'm having a little trouble with that machine but the drive does spin.

There were two MMIs, Microcomputer Memories Inc. (hard disks) and Monolithic Memories Inc. (chips). As the label on your disk says, it was made by MMI in Van Nuys, California, a small company which didn't last very long. Most of the Hyperdrives I've seen had MiniScribe mechanisms, which have 2 LEDs on the front panel, green for power OK / ready, and red for activity. Miniscribe went through a bad patch where all their drives died within 20 power on hours of use, and they refused to warranty them, claiming that they all had been abused. Minscribe also was famous for shipping bricks in HD boxes to meet their quarterly shipments goal and allow management to meet their earnings target. Obviously, this strategy only worked for one earnings report. ::)

As a result, most hard drive companies at that time sourced drives from multiple manufacturers. It would not be unusual to see an MMI, Miniscribe, Microscience, Rodime or NEC drive in any of these early boxes.

MMI references are few - they didn't last long:

Thank you for the interesting links on MMI. But would you know of any links to photos of the MiniScribe drives that show detailed drive information such as the model number? I am looking for something definitely that says "Here's a photo of a Miniscribe Model XXX" and of course looks exactly like the drive mechanism used in my Hyperdrive 512 (and that of The Nixer).

Thanks.
