Is it possible to install windows 2000/98/me/95/DOS on Arduino DUE? As arduino due is a fast enough 32 bit processor with enough ram and EEPROM to handle older windows os.
An Arduino Due has 512k of flash and 96kbytes of RAM.
Windows (starting with 3.1) required at least 2MB of RAM, and a processor with a "memory management unit." Due is immediately eliminated. The difference between RAM and Flash is relatively important in situations like this, because programs were loaded one at a time (and sometimes a piece at a time) into RAM, which you can't do with flash.
A better attempt might be made with the original Mac OS, which only had 128k of RAM (still more than a Due.)
Windows and MacOS also requires a relatively high-resolition graphics display (not present, or even really available for Due) and mass storage (also not present, though a microSD card would work.) Plus mouse and keyboard ports. If you went to a lot of trouble and did a lot of work (added hardware shields, wrote a lot of software), you MIGHT be able to get a Due to run some version of some a windowing OS for not TOO many more $$$$ than you could buy a modern Refurbished Windows-10 capable PC.
