ORCA/Modula-2
open-in-new
<p>ORCA/Modula-2 is a <a href="/facts/Modula-2/DFyUTdAq">Modula-2</a> <a href="/facts/Compiler/WNfCDFJe">compiler</a> written in the Modula-2 programming language for the <a href="/facts/Apple_IIGS/IXyL2fd4">Apple IIGS</a> computer. </p><p>It was developed by Peter Easdown during 1993–94 and published by <a href="/facts/The_Byte_Works/Y5289b0I">The Byte Works</a>. Whilst originally developed separately, when it was finally published, it was fully integrated with the development platform/environment called the Apple Programmers Workshop or ORCA/M. </p><p>The compiler was originally developed using a version of TopSpeed Modula-2 on an <a href="/facts/Intel_80286/rucEU93g">Intel 80286</a> based PC. The output of the compiler at this point was <a href="/facts/65816/5Ce9Nh4P">65816</a> <a href="/facts/Assembly_language/7XuV0cla">assembler</a> source for assembly by ORCA/M on the Apple IIGS. Once the compiler was stable enough, the <a href="/facts/IBM_PC/yhcJGMPL">IBM PC</a> was decommissioned, and all development was done on the Apple IIGS. </p><p>At publication, the compiler was shipped with comprehensive support for the Apple IIGS's operating system (<a href="/facts/GS%2fOS/j9Gxzu09">GS/OS</a>) and toolkit. </p><p>Due to the demise of the Apple IIGS, ORCA/Modula-2 never had much impact on the market. </p><p>The compiler development continued however for a short while during 1995, after which it stalled. </p><p>The <a href="/facts/Source_code/o9J6Jv23">source code</a> for the compiler can now be found on <a href="/facts/GitHub/n1hNCsc3">GitHub</a>. </p> <p><a href="https://github.com/pkclsoft/ORCA-Modula-2">https://github.com/pkclsoft/ORCA-Modula-2</a> </p>
