This is an early 386SX mainboard that was originally in a VOBIS Highscreen 386SX-16 big tower. It still has memory banks with DIL sockets. Due to parity 9 ICs are required per row and 18 to fill a bank. On the board 1 MB SIPPs are plugged (4 MB sum). There is a free socket for a NPU upgrade. The CMOS battery was removed due to slight leakage.
Notations on the mainboard are 'V-1 P9-8M'.
The board resembles closely a design found on Total Hardware 99: UNIDENTIFIED 80386 SX/16/20
