http://www.modcan.com/bmodules/904A.html Just above Joel's laptop screen there are two small lights (on the Scanner 69B), above that are a second pair of small lights. To the left of the second pair of lights is a 904A which is characterized by a 2-2-1-1 knob arrangement with the single large knob in the 3rd row with the single smaller knob in the 4th row offset to the right. What makes this certainly a 904A is the arrangement of the jacks at the bottom, a row of 1 and 4 respectively. No other Modcan B series device has this arrangement.
