This is the source code, binaries and listing output for the
SDS Symbol Assembler described in Symbol Tech Manual dated March 1965, with
catalog number 900688A. This source code was obtained using the
ocropus OCR system and first assembled by a cross assembler. The result of
that operation was then used to assemble the code again
on the simh SDS simulator to produce the .bo files in this directory.
The section-7 code is a version extracted from the PAL tapes contributed by JPL.
Some portions of that were removed to get everything to work. The standard
SDS release of this module could not be located.
The cat_sym.sh script collects the binaries into a single file, or card deck if
you will, prefaced with a one card loader program. The script also produces
a namelist file giving the values for external definitions. The order of
the namelist is that which would occur when card reader, card punch and
line printer modules are included at run time.
Instructions on how to use the assembler can be found in the Technical Manual
and the Symbol MetaSymbol Reference Manual, SDS publication 900506G.
Two simulator command files, sym_ascii and sym, are provided as examples
of how to run the assembler.
