     The 16k "Language Card" which expands memory to 64k should be in Slot 0,
the leftmost Slot when viewed from the front of the computer. A short 16-pin
cable plugs into the leftmost rearmost RAM socket (socket E3)-- you remove the
RAM IC and plug in the 16-pin plug.

     The "1986" may refer to the date the ROM or ROMs (or EPROMs) were
installed.

     It may be that someone installed the II+ ROMs or some special $F8 ROM or
PROM. (A special $F8 ROM may include a switch somewhere to pick Normal or
Special operation.)

     If do a Reset (or Control-Reset) you should be in Applesoft BASIC. If your
disk controller card is in Slot 6, entering PR#6 should boot the diskette in
Drive 1.
