+Skeleton driver for Reuters Model SK 101 BL trading terminal.
+
+This terminal is a small portable-sized unit with a 115-key keyboard, which is driven largely through LSTTL shift registers. The
+keyboard layout is similar to that depicted in patent EP0434224A2.
+
+Attached to the keyboard is a backlit LCD module displaying one row of 16 characters.
+
+The main board incorporates two DSWs and a "BLMHYB01" hybrid module containing unknown interface logic.
