It looks like yours has the same Memory feature mine has, so I guess it does have a computer in it LOL! OK - so it's got a memory chip and is hard coded, mine has not been to the shop since it was out of warrenty (got one free checkup) and DH has only cleaned it up a time or too, and I've used mine a lot!
BTW - I love my Viking. It's one of my few non mechanical machines.
