Bug#1010998: simh: Upstream license change conflicts with DFSG

[Joan Touzet]

As an alternative, Bob Supnik's "classic" version continues to release - 
version 2.12-2 just released 25 April 2022 - and would be an excellent 
replacement. http://simh.trailing-edge.com/

Unfortunately, that version still must overcome the licensing issues 
outlined in Debian bug #824883.
