Typically models ending in 00 use the term "hundred", i.e.:

6100: sixty-one hundred

9600: ninety-six hundred

People using the term "thousand" are sometimes, but not always, thought to be inexperienced.

And models with 4 digits not ending in zeros typically are said in groups of 2:

5260: fifty-two sixty

6116: sixty-one sixteen

Often times Apple II series, except specifically the original Apple II, are said dropping the Apple. i.e.:

Apple IIGS: two G S

Apple IIe: two E

Apple II+: two plus

Apple II: Apple two
