Wow, I hardly remember that.  I think they were 1200 baud
straight ascii and not AX.25 packets.  I cant find any such page
either...

Any old TNC going back 20 years can be used to TX these
announcements when your Retransmission is on the air.  They can
also be used to receive it if you are running any APRS software.
But few people run full APRS mobile with a PC anymore, since the
Kenwoods, Yaesu, and HAMHUD radios/devices make nice small
displays...
