      "This flexibly expandable computer grows by the increase of business activities and the rising requirements."

      A reliable office computer, which can flexibly adapt to the business work, as it is essential for the office to execute resulting works promptly, correctly, and precisely.\
      A user-friendly conceived EDP-system like the MZ-3541 is essential, particularly for small to medium sized companies.\
      The MZ-3541 contributes for a substantial increase of the productivity in the office by the assumption of routine works. SHARP has designed the new MZ-3541 in such a way that it can be used for the most diverse resulting office works. And because multiple peripheral devices are available, the system can grow dynamically with the business activities.

      The MZ-3541 is the result of Sharp's extensive market study and ergonomics studies. The free mobile keyboard makes data input and the operation easier and allows for spatial conditions an adapted installation of the system possible.\
      Sharp's MZ-3541 - the complete system for the business data processing.

This computer was not compatible with the other MZ series. It was the succesor of MZ-3200 series

Sharp started to sell 5000 systems in Japan in November 1982 before selling it to the rest of the world where it didn't meet a large success because of its high selling price and numerous options.

**Örjan Smith** adds:\
My first own computer was a SHARP MZ-3541. I used it for many years.\
I had both EOS and FDOS, but no other applications. I never did understand EOS, which was menu-based. FDOS meanwhile offered a machine-code editor (which I sadly lacked documentation for) and a BASIC interpreter with a typical 80's style line editor (with which I performed miracles :).

The ports on the back (RS232 etc) where all of the card-edge variety for flat cables. The second port on the front to the right of the keyboard port is the light pen port. The graphics mode required an add-in graphics board (which I did not have), and I think that was also required to get at the 8 colours mentioned (I'm not sure though, I had a monochrome monitor). Without it, you could still produce 160x50 pixel graphics by use of 16 quarter-fill characters in text mode.
