-Switch the L32-64-R32 switch to 64.
Use the 5110 model number to identify the
read / write storage size:
Model A11,B11,C11 = 16K
Model A12,B12,C12 = 32K
Model A13,B13,C13 = 48K
Model A14,B14,C14 = 64K
Model A21,B21,C21 = 16K
Model A22,B22,C22 = 32K
Model A23, B23,C23 = 48K
Model A24, B24,C24 = 64K
-Check the read/write storage size in the 5110.
-Switch the DISPLAY REGISTERS switch to
DISPLAY REGISTERS.
(See DISPLAY REGISTERS in the Diagnostic
Aids section in the MIM).

-Switch the DISPLAY REGISTERS switch to
NORMAL.
-Perform a calculation as follows (see the APL or
BASIC reference manual):
-For APL, enter:
B+-9 EXECUTE
C+-3 EXECUTE
A+-BxC EXECUTE
A EXECUTE
- For BASIC, enter:
B=9 EXECUTE
C=3 EXECUTE
A=B*C EXECUTE
