OS/8 was the primary operating system for the PDP-8. OS/8 is a single-user OS, used for support of application software.
All peripheral operations are handled without using interrupts. The file system uses contiguous files. Batch processing operation was supported by an extension.
It is different from modern OS's as you don't change paths/drives you assign the DSK: volume to whatever disk it is you want to work from (basically, defining the default disk).
Contents
Example of usage
delete basic.* deassign dsk: assign rxa1: dsk: squish sys: copy rxa0:<rxa1:*.sv R FRTS ADVENT (ESCAPE)
Some commands
BASIC
COPY
copy copys a file, but the syntax is different from most OS's...
copy Destination:<source:FILES
So that the follwing:
copy rxa0:<rxa1:*.sv
copys all the .sv files from rxa1 to rxa0
DELETE
deletes a file. You can use wildcards.
HELP
ODT
ODT is the Octal Debugging Technique: Or the debugger.
RUN
SQUISH
Squish is like defrag, in that it'll actually delete files, and move stuff around so you can get the maximum free space..
Interesting notes
OS/8 could run under another OS, RTS/8, as a virtualized guest. This made OS/8 be a background task in the RTS/8 context, but for the user, it appeared as a normal OS/8 system.
