The PCW 16 replaced the 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...
May 2009. Further to my previous posting about the PCW16 some five years ago, may I report that I am STILL using my PCW16 for all my general correspondence. What a splendid machine it is and still giving faithful service. Since I purchased it for a pittance, it has also proved to be great value for money. May it long continue !

Hi, the interpreter is finished and available! I am uploading it in the next few days. I found the author who was more than happy to release the code as Open Source! So check out my site soon for updates! I also have programs to download, manuals, articles and more there and coming soon!
As Alan Birt mentions, the PCW series still has a handful of faithful fans, thanks to its simplicity and sole focus on basic writing/office tasks. Sure, they're not remotely comparable feature-wise to modern PCs, but still orders of magnitude simpler to use if you just want to write a letter or report.
Anyhoo, some extra tidbits about the PcW 16:
The OS, Rosanne, is an astounding achievement; written solely in Z80 assembler, it incorporates a graphical WIMP environment with the usual menus, dialog boxes, etc. that are de rigeur on multi-GHz machines. Additionally, it's really nice to program for -- a good set of well-documented OS calls means you can knock up a graphical app in a few lines of Z80 asm. Someone started on a BASIC interpreter, but it never came to light. The only way to use another language (hosted) is to use the CP/M port.
PcW 16s have severe build-quality issues. I've had two fail on me, and from speaking to other '16ers', it's not uncommon for machines to stop working. Inside the machine, it's quite clear it was cheaply put together. A shame, because the keyboards were great!
Hardly any third-party programs exist for the '16. An accounting program was produced after launch, and there was the idea to utilise the machine's serial port (with modem) for rudimentary internet access, but that died out as the PCW line ended. By far the most significant 'external program' (in '16 parlance!) is John Elliott's CP/M emulator which, although not supporting graphics, is excellent for text-mode CP/M programs, thereby extending the '16's software capability dramatically.
Also of note is John's 'ANNE' emulator, based on his 'JOYCE' program, which emulates a PcW 16. It's currently in mid-development status but works pretty well.
The '16 is a fascinating little machine, but was perhaps doomed from the start -- computer shops are more interested in selling expensive and absurdly complicated machines to Auntie Ethel than a simple little word processor and spreadsheet. Same thing I see happening with the em@iler, which my parents use happily! Not much commission in flogging those devices :-)
If anyone's still using a '16, it'd be great to read about it on this site. Oh, and this is the first time I've visited this site for a couple of years -- kudos to everyone involved. It's retrostalgic tastic!
