lol i hear what your saying, i may not be a die hard amiga fan hence me not knowing what the boards exactly were, but i used to always envy the amiga screenshots in zzap being the owner of a C64 back in the day 
I have an amiga 1200 as well that i will use more often for gaming, so the 500 is surplus to my needs !
LoL fair enough, just wondered due to your post count.
I'm not 100% sure about that specific 2x speed 68000 CPU accelerator there but it may be possible that this unit can also be sold to earlier Atari ST owners as well as A2000/1000/1500 Amiga owners.
If you have an original 68000 for the A500 my advice is, if possible, remove the CPU accelerator and sell that separately.
