CES Ed-Lab 650?

This 1982 Ed-Lab doesn't have a model number or name at the top. It seems like it might be a 650 based on what's on a 651.

CES Ed-Lab 702 Digital Systems Lab

This one has a speaker on the back face for a boombox feel. It seems to be a newer version of the 700 with added keypad and LED digits and no meter.

CES Ed-Lab 700 Computer Systems Lab

Notice all the multiple jacks! I was surprised to see any multiples on a banana jack system.

There could be some potential educational clarity to using a multiple, but it seems sort of against the philosophy of banana patching.
