Try this:

Lines <- "Q1-60 26.528 1.268

Q2-60 27.535 1.087 Q3-60 27.737 1.346 Q4-60 28.243 3 Q1-61 26.462 3.272 Q2-61 27.769 3.863 Q3-61 27.903 4.606 Q4-61 31.673 4.1 Q1-62 28.211 5.395 Q2-62 29.469 5.554 Q3-62 30.249 4.903"

library(zoo)

# z <- read.zoo("myfile.dat", FUN = as.yearqtr, format = "Q%q-%y")
z <- read.zoo(textConnection(Lines), FUN = as.yearqtr, format = "Q%q-%y")
colnames(z) <- c("A", "B")

# 60 should mean 1960, not 2060

time(z) <- time(z) - 100

plot(z)

plot(z, screen = 1, col = 1:2)

Below is a sample plot I have made and want the X axis to represent a time vector with values taking the form Q1.60, Q2.60, Q3.60...Q1.90..etc...Currently the X axis starts with value 0 and increases by 1 through the end of the sample.
