Yet another interesting item that I recently ran through a Kryoflux is a set of 30 floppies labeled “IBM OS/2 Version 2.0 Pre-release Evaluation Copy – 6.304”. In this case, there’s no mystery as to what it is: 6.304 was the last beta of OS/2 2.0 released in February 1992, very shortly before the official GA release of OS/2 2.0. Very late in the game, this pre-release among other things introduced a new storage subsystem with familiar DMD and ADD drivers.
The trouble with this disk set is that it’s very incomplete. My estimate is that there should have been 32 disks in the set, possibly a little more. I have thirty, so it should be almost complete… except it’s not at all because a) there are duplicates of several floppies, and b) some of the floppies had been overwritten a long time ago.
The first missing disk is System Diskette 1, which together with the Installation Diskette is required to boot OS/2 at all. System Diskettes 5, 6, 7, and 8 are in the set, but overwritten. System Diskette 14 (the last of the system floppies) is missing. System Diskettes 2, 3, 9, 10, and 11 I have duplicates of, which does not really help.
There was a set of six printer driver floppies, of which I have all but one, but they are not that useful without an OS to install them on. There were also eight Toolkit floppies, plus another three Toolkit Debug floppies. Of those 11 there are only three in the set, but those aren’t essential.
The entire package should have consisted of the following:
- 1 Installation Diskette
- 14 System Diskettes
- 6 Printer Driver Diskettes
- 8 Toolkit Diskettes
- 3 Toolkit Debug Diskettes
That’s 32 floppies. It is possible that there might have been more, but there are no gaps in the part number sequence of the disks, so there’s a good chance 32 was the total.
All in all I have 17 usable floppies, just over half of the entire set. The real problem is that six of the 14 system diskettes are missing, including the first system diskette which contains the core of the OS installer and which is required to boot anything at all. What I actually have is the following:
- Installation Diskette
- System Diskette 2-4 and 9-13
- Printer Driver Diskette 1, 2, and 4-6
- Toolkit Diskette 1 and 7
- Toolkit Debug Diskette 2
All the floppies have a sticker “Souvenir of the SCOUG OS/2 Museum, Warpstock ’97”. If my recollection is correct, I got the floppies as a gift on a visit to the SCOUG (Southern California OS/2 User’s Group in Los Angeles) about twenty years ago. The set was already incomplete and partially overwritten.
So… does anyone have more of these disks? Perhaps even just one or two? Will it be possible to reconstruct this OS/2 2.0 pre-release, or at least enough of it to install the base OS?
