The Advanced Amiga Analyser is a fairly well known piece of hardware. It was advertised in the Amiga magazines in the early 1990s.
But I wish I could tell what kind of accelerator card is in that NASA A2500. It seems to have a daughterboard attached to it via two white pin connectors on the back of the CPU card.
http://tinyurl.com/yxhlhxIt might just be a stock A2630 by Commodore....chip layout is right. But did those have connectors on the back for a daughterboard (the BBOAH shows only the front side, where you can see solder points for those connectors)? EDIT: apparently it does have provision for a RAM daughterboard.
