Beige Against the Machine: The IBM PC turns 40.He has called the tool coffsyrup ( and you can take a look here.) The result is 1-2-3 for Unix, linked to glibc, which the Google guru calls 123elf. What Ormandy has managed to do is to build a tool to convert this ancient COFF-format object file into Linux's ELF format. The only way to release a proprietary application for all of these Unixes at once was to release a partially compiled object file, which could then be linked to create a binary for the specific x86 Unix variant you had. The closest thing to compatibility between them was an ABI called the Intel Binary Compatibility Standard or iBCS. SCO Xenix was the most prevalent, then its successor, SCO UNIX (largely the same OS, but with an officially-licensed AT&T kernel.) Others included AT&T's own Unix System V/386 and Interactive 386/ix. When 1-2-3 for Unix was released in 1990, there were a bunch of competing variants of Unix for x86 computers, all incompatible with one another. None were a big success and little trace of them remains today. With such a glowing endorsement, several leading PC applications were ported to Xenix, including Microsoft Word, WordPerfect – and Lotus 1-2-3. It's important to realize that MS-DOS is part of a family of operating systems… Providing the user with a family of operating system capabilities means a clear migration path from MS-DOS to XENIX.
