Looking for a Couple of Programs in Buster

["Martin McCormick" <martin.m@suddenlink.net>]

I wanted ckermit and a program called dosemu and apt-get says
they aren't available.  Here is the sources.list file I am using.
Are these applications really gone or is there another archive to
search

sources.list follows and I started out in stretch:

# 

# deb cdrom:[Debian GNU/Linux 9.9.0 _Stretch_ - Official i386 NETINST 20190427-11:18]/ buster main

#deb cdrom:[Debian GNU/Linux 9.9.0 _Stretch_ - Official i386 NETINST 20190427-11:18]/ buster main

deb http://ftp.us.debian.org/debian/ buster main
deb-src http://ftp.us.debian.org/debian/ buster main

deb http://security.debian.org/debian-security buster/updates main
deb-src http://security.debian.org/debian-security buster/updates main

# buster-updates, previously known as 'volatile'
deb http://ftp.us.debian.org/debian/ buster-updates main
deb-src http://ftp.us.debian.org/debian/ buster-updates main

Thanks.
