GST QL Assembler and Macro Assembler
In 2012, permission was given for the former GST QL software to be released as freeware. With much appreciated help from Rich Mellor, here are the QL Assembler and Macro Assembler packages. I am also grateful to Quanta committee for permission to make generally available the Quanta updated version of the Macro Assembler (Q-Mac as it was referred to within Quanta). As these files were prepared in good faith in rather a hurry on 24/09/13 , and I am not familiar with these programs, if anyone finds any problems please let me know so that any problems can be resolved quickly.
