[rescue] Sun 3/80 system part # questions

[Curtis H. Wilbar Jr.]

I have 2 3/80 chassis,

601-2203
601-2211

any idea why the different part numbers ?  Any idea if it depended on the
graphics option ?  drive options ?  etc ?

A google search didn't turn up much except a place called 'Recycled Goods'
that has a 3/80 available for $295.00 (hah !)
