Check the label near the ISA slots, this should be your board, J11 is definitely the battery connector.

I happen to have a Micronics board of similar vintage, they have a REALLY ANNOYING ISSUE. Besides having a BIOS from a 286 (my board has a Phoenix BIOS), you can't enable hardware shadowing of the BIOS if you install more than 16MB of RAM. More details in the link. I think this is a limitation of Micronics' custom north bridge. Otherwise they are very high quality boards that were Made in the USA.
