 ```Just looked and again I find that when I click on the button to download the manual, the software gets downloaded. ----- Original Message ----- From: Larry Kayser To: Sent: October 21, 1999 2:30 PM Subject: [TenTec] Pegasus Programming Manual some Clarifications > > Greetings all: > > I have received a very nice email from the factory clarifying some of the > items in the Pegasus Programming Manual.
