After 25 Years, 'Lost' OS/2 2.0 Build 6.605 Finally Re-Discovered (os2museum.com)

"In a fascinating example of poor timing, disk images of OS/2 2.0 pre-release level 6.605 from July/September 1991 were missing for over 25 years, only to show up literally one day after after the 25th anniversary of the OS/2 2.0 release," writes the site OS/2 Museum. An anonymous reader writes: It's the last OS/2 2.0 pre-release which didn't use the Workplace Shell (WPS), but "instead utilized the same old Desktop Manager as OS/2 1.2/1.3, which makes it the closest surviving relative of the Microsoft OS/2 2.0 SDK." Featuring a 16-bit/32-bit hybrid kernel and a "DOS Window" icon (as well as a few games like Reversi and Klondike Solitaire), "the look and feel was not quite the same as OS/2 1.3 and in fact was a cross between OS/2 1.3 and Windows 3.1."
The elusive 6.605 pre-release fell between 6.149 and 6.167 -- and "It is not known what possessed IBM to assign it a completely out-of-sequence number."

Re:OS/2 Warp 4: Better than modern Linux.

[Billly Gates]

Oh please!

OS/2 Warp is a better version of NT with a 1990s era kernel and usage. True Linux Desktop #### royally with the desktop and I gave up on it at home.

However, outside of the gui Linux has SMP scalable for 64 to 128 cpus, SATA, software raid, high end QOS networking functions, advanced power management and sleep, .NET, python 3, java, and api SDKs, oh and APPS!

Os/2 is not for modern age with support for 8 core 16 thread Ryzen or Xeon CPUs, modern mobile environments, HTML 5 app and browser support, or any server or database or language functioning you get with Linux and yes even Windows.

Hey CPM is fast to boot too but unpractical. OS/2 used to BSOD with MS showing it crash during the expos while NT could handle the same loads.
