    And the late 90's!
    The situation is a little more complex though. Pharmacia had an 
older instrument or two called the "Alf" and/or "Alf-red". I never saw 
one of those. But the Alfx -- that instrument rocked my world! 700+ base 
reads were common and there was a cycle sequencing kit available so I 
could sequence off 25+ kb subclones and lambda DNA.
    Anyway, I can probably dig up some .alx files. But I think I tried 
to read one with SeqIO once and it failed. So it may be that 
Bio::SeqIO::alf really only reads the older .alf files, not the more 
modern .alx trace file format.
    Phred could read them--poorly. It used the raw, rather than the 
processed traces, evidently.
