*Applies to lOP PCA only.
On the S-Bus, lOP Bus, and Selector Channel Register peA's,
open all switch positions of Sl and S2.
Then, close those
switch positions indicated with a C on all three PCA's for the
appl icable mode.

CURRENT INSTRUCTION REGISTER (CIR) PCA.
The CIR PCA con-
tains eight jumpers (WI through W8) as shown in figure 2-24.
If
neither
the
HP
32105A
APL (A Programming Language), HP 32233A
COBOL '74 or,
the Extended Instruction Set (EIS)
PCA,

are
installed
in the system, WI through W8 are all
installed.
If the EIS PCA is installed
in
the
system,
remove
jumpers
WI
and W8 from the CIR PCA.
Removing jumper WI enables
the floating point instructions and removing
jumper
W8
enables
the
decimal instruction set.
If the HP 32105A APL ROM's are in-
stalled on the EIS PCA,
remove jumper W2 from the CIR PCA to en-
able
the APL instructions.
If the HP 32233A COBOL-'74 ROM's are
installed on the EIS PCA,
remove jumper W4 to
enable the
COBOL
'74 instr uctions.
