I am not sure how to test this one. Being sold as-is.  I’ve been told that the I/O accessory is pretty rare and allowed for the tester to run BASIC.
DOES POWER UP. SEE LAST PICTURES !!  I hit reset and go CPU UP.   played with buttons and got the other two messages....  see pictures...
has that interconnect cable.   each has an ac cord.     NO Directions.  not fully tested !!!
The top on ETA-3400 has some sticky square pads.   the units need q-tip cleaned.
