MS-DOS (1981) 1998 DOS

Originally 86-DOS, written by Tim Paterson of Seattle Computer Products, DOS was a rough clone of CP/M for 8086 based hardware. Microsoft purchased it and licensed it to IBM for use with Microsoft's IBM PC language products. In 1982, Microsoft began licensing DOS to other OEMs that ported it to their custom x86 hardware and IBM PC clones.

Microsoft Visual Basic (1991) 955 DOS

First released in 1991, Microsoft Visual Basic was a programming environment where one could build an application by visually creating the user interface first, and then adding code. In contrast, even the smallest Visual Basic basic programs could take reams of program code to write in C or C++. Visual Basic was extremely popular for business application programming. The language itself was an interpreted BASIC dialect, however speed was maintained through the use of reusable compiled libraries (DLLs and VBX controls). These however, limited application development to Microsoft Windows.

Microsoft Windows Boot Disk (1995) 640 DOS

These disks are original boot floppy disk media for use with Microsoft Windows CD-ROMs. Not all Windows 9x/ME CDs are bootable, not all CDs included boot disks, and DOS will not see a CD-ROM drive unless a driver is loaded. OEMs were expected to provide compatible CD-ROM with the boot media provided with their systems. However towards the very late 90s, most vendors standardized on IDE/ATAPI CD-ROM hardware and the use of the OEM Adaption Kit (OAK) driver. If your CD drive is not IDE compatible (such as an MKE or Panasonic interface) you must manually add your own driver. Note: you can use the Windows 98 boot disk with Windows 95 to make things easier. If you have any UNTOUCHED OEM boot disks with different drivers, please submit them.

PC-DOS (1981) 334 DOS

IBM PC-DOS was an IBM branded version of MS-DOS licensed from Microsoft for use on the IBM PC system. Versions of PC-DOS paralleled that of MS-DOS up until version 6.1, where PC-DOS was independently maintained by IBM up until 7.1, the last version. Although not the only OS available for the IBM PC when it came out, it quickly became popular due to its low cost in comparison to the others. Its direct competitors on the PC at the time were CP/M-86 and UCSD p-System. The major differences between PC-DOS and MS-DOS were only in terms of driver support and built in programs until version 6.1 where development diverged.
