So late 1970s is probably the time you are looking for.

Just to fill in some info on the slightly later router history.

The Cisco AGS was released in 1986 and used the M68000 CPU connected to 
a Multibus backplane.  Lots more details available here: 
https://www.ciscopress.com/articles/article.asp?p=25296 The later AGS+ 
models kept the same M68000 CPU but had an improved bus (Cbus) for 5 of 
the slots to allow for higher throughput.

The 2500 series that shipped in 1993 (as well as others like the AS5200s 
based on them) used a Motorola M68360 CPU.
