Great - thank you! It was about the only one missing. Mind you, I've forgotten who created some of these PDFs so crediting them properly (let alone seeking permission to upload them) is going to be tricky. The Basic XL manual is from 8bitclassics. The MAC/65 one is an indexed PDF and I can't remember who put that together (several people, IIRC). I recall some heated discussions when folks started indexing other folks' PDFs a while back, and I don't want to tread on any toes.
I'm a bit short of Atari hardware manuals, but I think I have much of the ICD / OSS stuff covered. Nothing's been uploaded as yet.
