Just for fun (because I have a warped sense of fun), I decided to revisit some of the old OS/2 software I wrote
|
||
almost 30 years ago. But first, I needed an OS/2 development environment.
|
||
|
||
So I started with a clean install of [IBM OS/2 1.0](/disks/pcx86/os2/ibm/1.0/) in the 8Mhz IBM PC AT machine
|
||
below, by booting from the "IBM OS/2 1.0 (1.44M Install)" diskette in drive A and reformatting the machine's 20Mb
|
||
drive C.
|
||
|
||
Next, I installed the [MS OS/2 SDK 1.02](/disks/pcx86/tools/microsoft/os2/sdk/1.02/). This SDK was released
|
||
in December 1987 along with [Microsoft OS/2 1.0](/disks/pcx86/os2/microsoft/1.0/). I don't have any of the
|
||
printed documentation that came with the SDK, such as the *Installation Guide*, but I do have the
|
||
[Microsoft® Operating System/2 Programmer’s Toolkit](/pubs/pc/software/os2/microsoft/ptk10/) documentation
|
||
from March 1988, thanks to the [OS/2 Museum](http://www.os2museum.com/wp/os2-history/os2-library/os2-1-x-programming/).
|
||
|
||
Aside from **Microsoft Macro Assembler 5.00A** (MASM) and **Microsoft C Compiler 5.10 (Beta)** (CL), the SDK
|
||
included some other useful tools, such as the **SDK Editor** (SDKED), which was essentially an OS/2 port of
|
||
Mark Zbikowski's full-screen editor (Z) that was used internally at Microsoft for many years. It was renamed
|
||
to the **Microsoft Editor** (M or MEP) with the release of **Microsoft C Compiler 5.10**, and it was later integrated
|
||
into **Programmer's Workbench** (PWB), the text-mode Integrated Development Environment (IDE) that came with
|
||
**Microsoft C Compiler 6.0**.
|
||
|
||
With the introduction of graphical IDEs, such as Visual BASIC in 1991, Visual C++ in 1993, and Visual Studio in 1995,
|
||
this stand-alone, text-mode editor became obsolete, but in the 1980s, it was a valuable tool. You can learn more
|
||
about [SDKED](/disks/pcx86/tools/microsoft/os2/sdk/1.02/#using-sdked) on the
|
||
[MS OS/2 SDK 1.02](/disks/pcx86/tools/microsoft/os2/sdk/1.02/) page.
|
||
|
||
Our [IBM OS/2 1.0](/disks/pcx86/os2/ibm/1.0/) demo machine (shown below) has the
|
||
[MS OS/2 SDK 1.02](/disks/pcx86/tools/microsoft/os2/sdk/1.02/) pre-installed, so check out our copy of the
|
||
[Microsoft® Operating System/2 Programmer’s Toolkit](/pubs/pc/software/os2/microsoft/ptk10/) and then write some code!
