PC DOS 2000 review:1 stars (PC DOS 2000 CD-ROM) - According to the installation instructions in the User's Guide you must have a copy of DOS 3.3 or higher (THUS THIS IS AN UPGRADE). But, there is no indication in Amazon's advertisement or on the cover of the User's Guide that this is an upgrade. The first mention that it is an upgrade is on page xii of the User's Guide.So if you don't already have a version of DOS, DON'T buy the CD-ROM.5 stars (Best DOS yet) - I'm a big DOS games enthusiast and I've found PC DOS 2000 to be hands down the best version of DOS I've used. The best features of PC DOS 2000 are the amount of free conventional memory you can get compared to older versions, as well as the inclusion of ramboost, which is an excellent automated memory manager. I built another pc just for this OS (dual booted with win 2000 with no problems). Windows 3.x runs great in PC DOS 2000. I've been able to run many games perfectly that I haven't been able to run well or at all in almost 10 years. No problems running hardcore memory hungry games like Ultima VII. If you like DOS and you're using an older version do yourself a favor and pick up a copy.5 stars (IBM PC DOS 2000) - If you're truly an old hand at computers, you may still have 5.25 floppy drives, 2400 baud modems, AST memory expansion cards and maybe even a few CGA video cards laying around. Do you remember RLL hard drives of less then 50 Megga bytes? How about LIM ver. 4.0? If you know about this stuff, you're probably also a big fan of the command line. If so, DOS is for you. And THIS DOS is probably the best out there, not to mention last. Like most DOS OSs, (and unlike GUIs) PC DOS is fast, boots and loads/runs programs nearly instantly, and works quite well with Windows 3.x. PC DOS 2000 comes with plenty of utilities plus the REXX programming system, built-in Antiviral protection and good documentation. I recommend it highly!
