it looks like an zydecs megaboard. number of chips hint 1mb ram, and pass through connector is most interesting, probably with the gary adapter you can put an extra 512k or 1mb there for a maximum of 1.8mb (maximum for ranger memory ?)

@coze

a good shot their, but because of the pass through for another chip upgrade i think that its actually the AMRAM MegaBoard that can have up to 2MB of ram with an additional ram board.

Details from amiga.resource.cx

MegaBoard by Zydec, UK
Date 1992
Amiga A500
Interface trapdoor slot & Gary socket

Features
- 1 MB RAM - gives 1.5 MB total
- eight 256k×4 DIPs soldered onto the board
- connects to the trapdoor slot
- an adapter board connects to the Gary socket
- expandable with a standard 512 kB trapdoor slot RAM expansion (not exceeding 9 cm in length) for 2 MB total
- disable switch
- requires Kickstart 1.3
