Alessandro,
As far as I know there are now equivelant replacements for the 74hc237. The
74hc138 does the same thing but outputs an inverted signal. If you are any good
at electronics you can fudge a 74hc04 into the prototyping area to re-invert
the signal, and use the 74hc138 in place of the 237.
Or try Digikey or allied electronics, but I didn't have much luck.
