..."Local Bus S3 VGA Accelerator". An S3 911 perhaps?
It seems to be quite a large chip, maybe S3 805?
The mainboard itself is quite well performing with a ST DX2-80 5V CPU.
I love all the AIR and ALR stuff, the build quality was excellent.
The 4 chips of the chipset are also labeled:
DBC - Data Bus Controller
MCC - Memory Cache Controller
EBC - EISA Bus Controller
ISP - Integrated System Peripheral
Did they mix 28-pin (narrow) and 32-pin (wide) cache chips? How did that happen?
