It has been a couple of years since my introductory guide to PCem, which took a look at Version 11. As of now, it’s up to Version 14 with enough changes to warrant a refreshed guide. Some of the numerous improvements since then include supporting Voodoo 2 3D graphics, Iomega ZIP drive, network card emulation, and IDE drives up to 127 GB. PCem also has had a visual makeover so it’s more intuitive to navigate.
One of my earliest laptops is this IBM ThinkPad 755Cs dating back to 1994. According to the website ThinkWiki this model came with a colour display, either a 486 DX2 50 or DX4 75 Mhz processor, 4 MB RAM, 1 MB Western Digital WD90C24 video, Cirrus Logic CS4248 for audio, and a choice of a 170, 340, or 540 MB hard disk drive.
This particular one was maxed out with the DX4 processor and 540 MB drive, so it fetched some decent coin when new. It had also been upgraded to 20 MB RAM at some point.
OS/2 initially developed in cooperation between Microsoft and IBM back in the 1980s had a turbulent history over the years. By 1996 with the final retail release of OS/2 Warp 4.0, IBM conceded defeat by Microsoft realising it was not able to compete with Windows 95, although still managed to withhold a portion of the enterprise market. Years later it was still found on some servers and even ATMs on the street.
OS/2 Warp 4.52 was the final version by IBM released in 2001 with official support ending in 2006. It wasn’t offered in a retail package, but for those who had a contractual agreement with IBM for OS/2 support. After this the foundation of the OS had evolved into what is now known as eComStation.
IBM released the ThinkPad 380 series back in 1997 as a mid-range laptop to use essentially as a desktop replacement. These were part of the long running 300 series dating back to the early 1990s when IBM released a 386 laptop known as the ThinkPad 300. While initially housing the original Pentium processors, the 380 series had typically used a Pentium MMX or later a Pentium II. From what I can tell, these normally were preloaded with Windows 95, though drivers are available for Windows 3.1, NT, and OS/2 as well.
