The PCW 16 replaced the [PCW 9512](/museum/amstrad-pcw-9512/). Contrary to the previous models, which used a text-based interface, the PCW 16 used a graphical user interface called The Desktop. The computer didn't run CP/M like the old PCW computers, but had its own operating system called Roseanne. Even though CP/M wasn't supplied, it was adapted to this machine by independent developers.
Unlike the previous PCW models which came with only the Locoscript word-processor, the PCW16 came with a complete range of built-in software - word-processor, spreadsheet, address book, diary/alarm, calculator and file manager.
Luckily, Amstrad abandoned the Hitachi 3" floppy format and switched to the standard MSDOS 3.5" 1.44 MB double-density floppy disk. The Roseanne system could use long filenames (up to 31 characters). The display was also standard: 640 x 480 VGA mode.
Amstrad provided Several internal expansions for the PCW-16, 1 MB RAM, 2 MB Flash RAM, Application ROMs, second FDD drive; but it seems that none of them saw the light.

**Rob W.** remembers:\
Dixons UK were selling the PCW-16 as late as December 1997, bundled with a Citizen Dot-Matrix Printer for about £170, which seemed expensive, but up against the latest £1,999 P233-MMX Packard Bell at the time, it seemed somewhat cheap :)\
Sadly, despite being taken in by its psychedelic keyboard colours and constant nagging, my dad didn't buy me this :(\
But... the following year he bought me a P233-MMX for £600 and the rest is history.\
Unfortunately, I have not seen one since. Wonder why...
