I have a "Toshiba Satellite T2100 Series" mobile computer. My specific model is a Toshiba Satellite T2105. It has a 50MHz Intel i486 DX2, 4 megabytes of memory, and an upgraded hard disc of 2 gigabytes. These machines shipped with Windows For Workgroups 3.11, or Windows 95.
Interestingly enough, the manual for the machine makes it sound like Toshiba did not actually ship to you a set of floppy discs with the software on it. Instead, you were given an application that, like on modern Sony Vaio computers, helps you make a restore/install disk set. The idea is nice, but honestly? Every other vendor I know of in that time period had actual install disk sets.
The machine performs excellently with Windows For Workgroups 3.11. It is probably about as responsive at most tasks as Mac OS 9 is on a reasonable G3 system with 128 or more megabytes of memory. I was personally quite impressed with this operation. Under IBM's OS/2 Warp 3, performance is somewhat less stellar, the word processor app has problems keeping up with a slow to moderate typing speed, and wouldn't be suitable for everyday use. Windows 95, although being just as code-heavy as OS/2, seems to leave the system much more responsive to user input, even with an actual word processor like Word 95. Of course, it takes on average, five to six minutes to reach this state of usability. Windows 95 is, overall, significantly slower in all standard operations.
