After a quick Google search, it looks like the company's name is Dove, and MacSnap being a brand. From this company I'm only finding SCSI mods and RAM upgrades for the early compacts, but no ROM upgrades. They apparently were focused on making the 128k and 512k models into Mac Pluses, so it makes me wondering if this board was part of a floppy drive upgrade sold by the company.

If I had to hazard a guess, my gut feeling is this device implements a few hacks (which literally might just be changing a few one byte constants) to the hardware initialization routines in order to enable a really old Mac (perhaps only Macs with the original 64k ROMs, which would mesh with the 32k size of the EPROM) to recognize more than 512k or RAM, and thus work with one of their "MacSnap" one or two MB clip-on memory boards. It appears that when said board was sold with a SCSI expansion (with resided in *both* ROM sockets and required 128k ROMs) the complete package was called the "MacSnap 524S". This just says "524", so if the "S" means SCSI...

This is highly likely. Maybe they sold more then 1 kit.

Here is some more info from VintageMacWorld I found from a Google search:
