- IBM PC DOS (an acronym for IBM Personal Computer Disk Operating System), also known as PC DOS or IBM DOS, is a discontinued disk operating system for the IBM Personal Computer, its successors, and IBM PC compatibles. It was manufactured and sold by IBM from the early 1980s into the 2000s. Developed by Microsoft, it was also sold by that company as MS-DOS. Both operating systems were identical or almost identical until 1993, when IBM began selling PC DOS 6.1 with new features. The collective shorthand for PC DOS and MS-DOS was DOS, which is also the generic term for disk operating system, and is shared with dozens of disk operating systems called DOS.
- Paraguay-Latin America: The Case of Dr. Mengele (PDF) (cia.gov)
The search for German war criminal Josef Mengele has centered on South America, long a haven for Nazi fugitives. Paraguay has been a special target for investigators. Mengele reportedly lived there during the early 1960s, and some Nazi hunters believe he still resides in Paraguay under official protection. Mengele, a physician, is accused of selecting tens of thousands of inmates at the Auschwitz concentration camp for medical experiments or extermination in gas chambers.
