  We have computed the time-dependent susceptibility for the finite-size
mean-field Random Orthogonal model (ROM). We find that for temperatures above
the mode-coupling temperature the imaginary part of the susceptibility
$\chi''(\nu)$ obeys the scaling forms proposed for glass-forming liquids.
Furthermore, as the temperature is lowered the peak frequency of $\chi''$
decreases following a Vogel-Fulcher law with a critical temperature remarkably
close to the known critical temperature $T_c$ where the configurational entropy
vanishes.
