This is the contents of the hard disk of an Archimedes A500 belonging to Logica
in the 1980s. It's a copy of LogicaA500 Host FS zip
on
the Domesday86 site.
The extraction was done by Ian Stocks. Major kudos.
Where you have two subdirectories B
and C
, B
will contain BCPL source
and C
will contain the compiled images of that source.
The Archimedes filesystem was not case-sensitive. The RISC OS character encoding is a bit like ISO 8859-1, but has its quirks.
