This archive conatins a first beta release of ST-Oberon V4, an implementation of the ETH Oberon System V4 for Atari ST & TT computers. The system is supplied with an Oberon(-1) compiler, a linker and comes with complete source code. ST-Oberon has been tested on TOS 1.0 and 1.4 on a 1040STF, a MEGA ST2 and a Stacy. It may be that the current version of Oberon won't run on the newer TOS versions, since it uses some system variables, and modifies the exeption vectors. Hardware Requirements: Atari ST or TT computer with at least 2 MB RAM (for serious use, altough ST-Oberon will also run with only 1 MB) 4 MB of harddisk space, preferably on a harddisk connected to the ACSI port. The following files are contained in this distribution: SYSTEM.LZH the main archive containing - KERNEL.PRG the Oberon System loader. - $$OBDISK.IMG the data file containing the virtual Oberon harddisk partiton. - PCMOUSE.PRG a tool to connect a Microsoft or Mouse Systems compatible serial mouse to your Atari. - PCMOUSE.S the assembler source code of the above tool. - README.TXT this text. PR3FONTS.ARC an Oberon compressed archive containg the *.Pr3.Fnt fonts needed by the postscript printer. SOURCE.ARC an Oberon compressed archive containing the sources of the system. To start Oberon, unpack SYSTEM.LZH and execute KERNEL.PRG. have fun! please send bug reports or feedback to eglis@ubaclu.unibas.ch under the subject "stoberon".
