I still have my copy of the book by Michael Singer: http://www.amazon.co.uk/Introduction-DECsystem-10-assembler-language-programming/dp/B0007AJF54/ref=sr_1_1?ie=UTF8&qid=1456948533&sr=8-1&keywords=singer+decsystem. This is the book I used to program a DECSYSTEM20 in assembler, although I must have used other resources to help me along that I no longer recall. The book is available at a much more reasonable price than the Gorin book (which I don't have). Regards Rob
