   That sounds about like it. RAM is 4 ea 2111A-4. There is an unmarked
1702 EPROM (A15) and an empty socket (A16) next to it. Does your's have
an IC in A3? If so can you tell me the type? Is there supposed to be
something mounted to the left of the keyboard? Mine is barren but there
are screw holes there.

   Yes I'd like to see it.

  That's my problem, no time.
