Hello, i had been trying to find the 8086 instruction format, but all i found is 80386+ (that is oriented to protected mode). Does anyone has something?

Thanks

The original 8086/8088 opcodes? I found a few documents via Google...

For later processors, order the hard copy books from Intel.

go there, and then just filter out what is above 8086 (it will say 186+ or 286+ or whatever beside it if it is only for those cpus)
