Another collectible 386 Mobo but no brand and model
8 Pin30 SIMMs
8+1 DIP28 cache sockets ( 128KB cache preloaded )
AMD 386DX-40 / Intel i387DX-33 preloaded ( dual sockets )
OPTi 82C392 / 82C391B / IMP82C206P chipsets

There are little leakage around the battery
Fortunately, it can still boot and work normally
BIOS looks a bit old and don't support HDD auto detect

Some jumpers are not defined
They should be related to cache configuration or CPU / FPU
Does anyone have this motherboard or some hints?
