Rev 8 is a standard AMIGA 500
Rev 8.10a is the AMIGA 500+ that has the ability to do some extedned graphics reolutions due to an updated Denise chip and not much else. The trapdoor fast ram is not true fastram, but slow chipram re-mapped to the fastram address. It was nicknamed SlowFast ram.
p.s. I also have one
What I don't have is a AMIGA 1500 or was it the 2500

I forget now.
