I had all of those books, yards of them, as they came out. But no one but board designers used the data books, they're were tediously hardware oriented.
What we all used were the cheatcharts. Foldout instruction set summaries.
Oh how I wish I had my collection! I had probably 25, chips if written code for. Weird stuff like 8x300. Cosmac. Weird little Intel and moto.
The cheatcharts are what you want. All dog-eared torn and coffee stained from use.
But the datebook will have the official instructions descriptions and assembler mnemonics in excruciating detail.
