Originally, the computer came with no documentation. However, we have an original owner's manual (see below).

The computer is composed of five separate units, see the "Images" section for photos. The units include [1] the main computing module which is pictured just to the left (LAN-ALOG type LA 4) and which has four potentiometers, [2] a patchboard (LD-20)which doubles as the power supply, [3] a second patchboard (LD-15), [4] a Counter Unit (LD 80 C) and [5] a Relay Control Unit (RCU-5). We powered up the LD-20 unit, which contains the power supply, and the power light went on. The cables that supply power from unit to unit appear to have some kind of 5-pin DIN interfaces, like a misshaped "5" on a die.

     We were surprised to find an old-fashioned (well, not old-fashioned for 1966) phone dial in the bottom right corner of each patchboard. We are not sure how that was used to enter data. See the "Images" section for closeups of the phone dials.

     Strangely, some of the units have bottom plates, and some do not. The ones that do not have bottom plates we assume never did, because there are no screw holes to adhere them.

     Another unusual feature is the size of the patch cord inputs. They are not the standard "banana plugs" of the era but are much smaller. Unfortunately, no patch cords came with this computer.

We are not sure when this computer was originally manufactured. We believe it to be in the early-1960's. We base that on the "LAN-ELEC Digital Educational Computer Handbook" (see below) which is dated Dec. 1963. The computer may have been produced even earlier.
