Does anybody know this hardware on lefthand side ?

[holger.müller]

Hi all,

several years ago, I removed these PCBs.
I can only identiy the AT-Speed with Blitter Patch on righthand side, but I don't know the small one
on the left side.
Does anybody know or recognize this PCB ?

Best regards
Holger
