These files are suitable for intalling ATOS on a real Atari 8-bit computer that has a hard drive. They contain the same atos.arc file as what is found in the files1 directory. Atos.arc has been split up into several 80k files to allow users to copy them to floppy disks on a PC and then read them on their Atari 8-bit computer. The steps to install ATOS by using these files are as follows: Step 1 Copy each of them to a floppy disk on the PC. You will have to use a suitable utility to copy it in a format that your Atari 8-bit computer can understand. A double density floppy can hold two of these. A single density floppy can hold one. Step 2 Take these files to your Atari 8-bit computer and copy all of them into a D1:>temp directory on it's hard drive. Step 3 Type "-UNSPLIT". This will join these files into a single ATOS.ARC file. It will then unarc them into the correct directories. Note that unarc must be found in your path. Additional configuration instructions can be found in the ATOS web pages and WWW board.
