Hi Mark,

Odd, someone else was just asking about that version a week ago.
Companies come and go, websites are subject to fad, products become
unsupported. But here are 14 versions from my personal archive:

http://leapsecond.com/museum/xli/

Also, can you tell us why you're asking, what's special about v2.4, or
how well an XLi still works these days?

In general it's a great-for-time-nuts miracle that GPS receivers from 20
and even 30+ years ago still work fine. I used to think Western Electric
and Micro-Soft were rare examples of olde tyme respect for backwards
compatibility, but RS-232, WWV/WWVB, and GPS/DoD/2SOPS are also on that
list.

Let us know if you need more help. Pretty sure many of us have Datum /
TrueTime / Symmetricom gear from that era and can help you out.
