4OS2 Versions

This is my (incomplete) collection of old 4OS2 versions. I have listed all old 4OS2 versions I got or know of. Any help from you to find the missing versions is very much appreciated. Note that these are all legitimate shareware versions and you need the appropriate brand program to register them.

Most of these files are mainly of interest for research purposes. For actual use select the final, most bugfree reelase of a major version.

Freeware Versions

 

For the following information I am grateful to Richard Steiner, who cleared up some of my confusion over the various versions floating around:

The development of 4OS2 has indeed been shelved by JP Software, but thanks to their generosity (and release of the source code) there are still improvements being made by third parties.

The source for 4OS2 3.04 was given by Rex Conn to Michal Necasek at SciTech Software (makers of SciTech Display Doctor for DOS and the well known SNAP Graphics drivers for OS/2 & Linux), and Michal has released a number of versions containing minor box fixes to the OS/2 community.

These new versions have been numbered 3.04B through 3.04G (the last release just made on 30 July 2005), and the only help file contains all of the changes in the "What's New" section.
There was no SciTech version 3.04A, just B/C/D/E/F and G.

The last three versions are available here on the SciTech web site:

• 4OS2 3.04e

• 4OS2 3.04f

• 4OS2 3.04g

and this page leads to their ftp site.

The source for 4OS2 3.04B is available on the Hobbes FTP site. This source compiles using the freeware OpenWatcom compiler for OS/2, which is quite convenient.  

Michal Necasek's and Steven Levine's 3.04H, Open Source Edition [2007-
05-09] is  posted at Open Watcom:

• 4OS2 3.04h

Difference from 3.04G, SciTech Edition:

- Fixed shift /1 crashes
- Fixed spurious REXX error reports

To make things a little more complicated, another OS/2 programmer and long-time 4OS2 enthusiast (Doug Lindquist) found the 4OS2 source files on Hobbes and decided to make some changes and minor enhancements of his own before SciTech's (Michal's) involvement was very well known in the OS/2 community.

Doug's versions were numbered starting at 4.00A (mainly due to some larger changes he had made), but associated problems and conversations with Michal on comp.os.os2.apps has resulted in his version being discontinued in favour of a unified version from SciTech. His versions were 4.00A, 4.01A, and 4.02A.

• 4os21125.zip

• 4os2401a.zip

• 4os2402a.zip

Hope that helps clear some things up regarding 4OS2 and the nature of the various versions that are floating around.
