thej Posted December 4, 2018 Share Posted December 4, 2018 (edited) The entirety of the PC/GEOS operating system, it’s SDK and apparently, ALL of it’s software, have been posted up on Git for community availability and further development ! It appears to be at least PC/GEOS 2.0 and possibly newer. Many files are dated 1991 and many have additional revision dates of “97/04/04 NewDeal” which is at least version 2.5 I believe. Most of the code is written in C and an updated (??) Watcom C compiler is also available from the author on his Git. It was common to write GEOS software with “ObjectASM” in x86 assembly. Their object technology was a key advantage they had over other OSes at the time. You can find the Git repo here: https://github.com/bluewaysw/pcgeos Here is the Wikipedia page: https://en.wikipedia.org/wiki/GEOS_%2816-bit_operating_system%29 …and here is a link to a PDF of the “PC/GEOS System Software Overview”. This document gives an overview of the system architecture and other details for developers. It is specific to ver. 1.0 of PC/GEOS. https://www.lyonlabs.org/commodore/onrequest/geos/PC-GEOS-System-Software-Overview.pdf j Edited December 4, 2018 by thej 5 Quote Link to comment Share on other sites More sharing options...
