SC_P03 is a compilation of SC_PD1 and SC_PD2 with an extra bonus utility Search: “SC_DISCLONE”.
There are two seperate Manuals for SC_SPECLONE and HUMPHREY (the only program that Steve did not write, its by Matthew Holt of Manic Miner fame).
All instructions for installing, manual, adverts, and my personal notes are in the PDF.
Assemble source for most of my products and a way to verify I have given full permission can be found separately under SC_Assembler source files on this site.
