Looking at the 68881 user's manual ...

https://archive.org/stream/bitsavers_motorola68anual1ed1987_15689294/68881_68882_Users_Manual_1ed_1987#page/n244/mode/1up

... it seems like both are wrong - 68881 can report 0x1f and 0x3f, and
68882 reports 0x1f. Newer versions of the FPUs could report even other
version numbers. To distinguish both, the length field should be used
instead, I think.

I've cc-ed Toni Wilen ... maybe he knows where the 0x20 comes from...?

I have no idea where those 2 values came from, they were there before I knew nothing about UAE and I assumed they were correct.

I just tested what my 68030 based Amiga 3000 with 68882 returns, version number = 0x1f. Unfortunately I don't have any 68881s.
