Hi afther i found this nice forum with google it would be nice to join, i'm also the owner of the folowing series
U100,110ct,100ct and 70CT.
The use of the 110CT for me was DOS program's and windows applications.
I use dos more my very old games quake, duke3d, lemmings, wolf3d etc but also play music mp3 (underdos) mod s3m xm it music files something like midi music at that time of the 386 486 computers i was more grownup with the 8088 and the 80286 PC's. A DOS background will never leave me heheh

Its also why put these old stuff on the libretto.
I use windows 98se for programming for micro controllers in electric circuits to do there tasks example drive a steppermotor or control a lcd HD44780 controller, application programaming in C++ for windows and programming for CNC LASER cutting using G -CODES to creat a product from metalsheet it also tobe apart of my job just writing codinatings in x and y and execute the program on the trumph laser machine to create the programed product.
Other purpose use is viewing small mpeg movi's and playing mp3 files.
