The MD-88 was the first variant of the MD-80-series to appear with EFIS cockpit,later,all MD-80's had this layout.
The real diff. between the MD-88 and the other variants was that the -88 was designed to be readily available for conversion to the planned Propfan engines being tested during the late -80's.This,however,never materialized.
The -219 engine is an option for all -81's and -82's,as well as being standard on the -83.
In SAS,we've got -81's,-82's and -83's,all with the EFIS cockpit,-217C/-219 engines and all have the screwdriver (or beaver) tailcone.
