Hi Gennadiy, I found this mainboard:
http://saul.pointclark.net/m/A-B/32079.htm
It has one CPU 486BLX3 (132-pin) at 25/75 MHz.

the number on the top is 50G3589.

Ciao!
Vinicio from Italy

These are commonly called "silvercaps". It' an Intel 386DX core in IBM packaging. For this particular FRU (there are FRUs of 51F1797 & 63F7615 that return CPUIDs of 0305h) it has been the only 'C' step 386DX (CPUID 0303h is the 'B' steps, 0305h starts the 'D' steps...) I have ever heard about, returning a CPUID of 0304h!
