Ordinarily, I would simply direct you towards Google, but after quickly checking the results myself I find that there aren't many such resources to be found. This online textbook is probably the best resource I was able to find.
Wow thanks so much. Yeah I looked Google first before posting and actually I've been using the Computer System book J. Stanley Warford who actually programmed Pep/8. Thans, this book is clearer than Warford wrote.
