I'm with Bloodline on this one... a doubtfull but possible explanasion is that it's equipped with an A2000 040 turboboard where the 40Mhz/040 have been overclocked to 60Mhz and where he's seen the 120Mhz crystal, or a Deringer 030 card overclocked to 60Mhz... though as Bloodline said... it's likely to be an old PC with an A500 manual.
