iSBC 337 Numeric Data Processor
The iSBC 337 Numeric Data Processor is a high-speed, floating-point math
board which allows a quick and easy upgrade to floating-point math for
the iSBC 86/14/30 board.
The iSBC 337 Numeric Data Processor is designed to be mounted in the
existing 8086-2 CPU machine socket (U48).
Refer to the iSBC 337 NUMERIC
DATA PROCESSOR BOARD HARDWARE REFERENCE MANUAL, Order Number 142887, for
more information on the board.
The following steps describe the method
of installing the iSBC 337 board onto the iSBC 86/14/30 board.
1.
Unpack the iSBC 337 Numeric Data Processor.
2.
Inspect the iSBC 337 Numeric Data Processor for damage.
If
damage exists, follow the instructions for repairs in Section 5
of this manual.
3.
Turn system power off.
4.
Remove the iSBC 86/14/30 board from the backplane and place it on
a soft surface (preferably a piece of foam), component side up.
5.
Remove the 8086-2 CPU from socket U48.
6.
Insert the iSBC 337 board mating pins into socket U48 and the
other mating pin (P2) into the jack (J5) on the iSBC 86/14/30
board.
Ensure that pin 1 of the iSBC 337 board is aligned with
pin 1 of socket U48.
7.
After ensuring the seating is firm, insert the previously removed
processor into the socket pins of the iSBC 337 board.
Ensure
that pin 1 of the processor is aligned with pin 1 of the socket.

iSBC 303 Parity Generator/Checker Multimodule Board Installation
The iSBC 86/14 board accepts an iSBC 303 Parity Generatory/Checker
Multimodule Board; the iSBC 86/30 board does not.
The installation
procedure is contained in the manual for the iSBC 303 board, contained in
this manual as Appendix C.
No jumper configuration is required, other
than the interrupt priority level configuration.
The iSBC 303 board is
installed over the iSBC 300A RAM Expansion Multimodule Board if both are
required in the configuration.

iSBX MULTIMODULE BOARD INSTALLATION
The iSBC 86/14/30 board provides two iSBX Multimodule connectors (J3 and
J4).
When an iSBX Multimodule board is installed, the iSBC 86/14/30
board's power requirement will increase by the amount specified in the
iSBX Multimodule board manual.
Install the Multimodule boards as follows:
