You can find a lot of them as PDF files on archive.org, along with a lot of the other classic computer & programming books. Zak's, Osbourne, and others,? tech manuals from the manufacturers, etc.
I don't know if I have the brainpower to actually use them anymore, but have downloaded a bunch of them myself.

Are you reading any books on the Zed-80?

Hi Josh, I dont remember that instruction, but I know it had quite a few more that were better than the old 8080 as well as an improved register set. I know that the HW took the 3 power supplies from 3 down to 5V only. Really great for that time. IIRC I think that is why Intel came out with the 8085? Wow so many years ago, I am mixing up what they did back then. As I read frm down below, I also mixed up the company names as well. LOL!! I think I was on the 6800 - 6502 path in my mind, not on the 8080 - Z80 path. So many things happened back then. Now so little memory left of what happened as well I believe. HEHE--thank God I am not a writer of computer history and such! lol As far as books, all I have left relating to the Z80 was the one I got back in the early 80's called "the Z80 microcomputer handbook" by Wlliam Barden jr. I read a bit of it back then when were designing a computer system for a new product that were making but went to the 8048, 8031 and other MCS51 stuff for our final design. I was not into home pc's back then so much for my career but into more controller applications that we were doing. MCS51 rocked the world for us. Home use I went from 1802 and 6502 stuff. Why, I really have no idea. I guess I just liked them all.
