OK, here goes!
To explain a bit, the disks arrived all in a jumble stuffed into two disk boxes (oldappleguy said he couldn't read many of them on his 128K, so he just sent me everything that looked relevant - thank you!!), so I had to do a bit of figuring to put them in order.
First of all, I locked all the disks and imaged them in DiskCopy 4.2, so the contents of the images are the disks exactly as they came to me. Then I renamed the images (that is, the modern wrapper, not the disk on the inside, which still has its original title) and organized them in folders in what I think was the order of their release. I've attached the 400K disks in one bundle and the 800K disks in another. Stuffed with Stuffit 3.5.
One additional bundle is a set of 400K disks that I recreated from my own working Hyperdrive. This computer, which contained files loosely organized in a folder, came to me without install disks, so I used the various disks here as a guide to figure out which files went on which disk, and recreated three install disks to use if my machine ever goes down. My files seem to represent the 5.1 version (Feb 86) of the original release, which preceded the release of V2R1 in March 86. This is the "V1_recreated" upload.
As far as I can work out, the version history for the early versions was:
Sept 85 - original release of the HyperDrive and its system software (V1 Disk 2 seems to belong to this version; Disk 1 sadly is the one that remains obstinately unreadble)
Feb 86 - 5.1 update of original release (running on my unmodified 512K)
Mar 86 - V2R1, provided support for HFS, but with some limitations explained in version doc
Aug 86 - V3R1, presumably a more stable release for the Plus
V3R2 and the various FX versions followed, but I haven't studied all of those closely.
I'll follow this up with a comment to attach photos. I don't want to clutter this post with my sixteen photos (can't zip them up because the post editor says they're too big!). Eventually I want to make proper archival scans of the disks, but that always seems to take me forever.
Included were a batch of "Backup Disks" which did not contain HyperDrive related files, but rather copies of applications that must have been on the original owner's drive. I imaged them, but haven't uploaded them (I can, if anyone wants them, but I think the applications are mostly to be found on Macintosh Garden). I did however make a scan of one of the labels, in case olePigeon wants to add to his label collection.
Let me know if you see any problems or want more details. I'll be out most of today, but wanted to get these up. They'll go up on Macintosh Garden eventually as well.
