DESCRIPTION

Jumpers J1-J3 are removed to select board address FFF520 H.
Insert PCB jumper J1 to select board address FFF560 H.
Insert PCB jumper J2 to select board address FFF580 H.
Insert PCB jumpers J1 and J2 to select board address FFF5C0 H.
Insert PCB jumper J3 to select board address FFF620 H.
Insert PCB jumpers J1 and J3 to select board address F520 H (Short I/O).
Insert PCB jumpers J2 and J3 to select board address F560 H (Short I/O).
In reference to the PCB:	J1 = E13
				J2 = E12
				J3 = E11
If the ICP8/16 board is to be mapped into short I/O (VME_AM = 2D H, short
supervisory access) be sure to insert jumper E15. This forces PAL U85 to
decode only the address modifier lines. By inserting E11 and E13 or E11
and E12, address bits 1 - 15 are decoded and 16 thru 31 are ignored provided
jumper E15 is inserted. DO NOT jumper E11 and E13  OR  E11 and E12 without 
jumper E15 being in place !!!!!!!.

			revision level
release A1: Initial preproduction realease
release A2: Add VMEA5 into the VME address decode. Because this address bit
	wasn't decoded an icp8/16 card would interfere with a tape(TC50 or
	QIC2) at address FFF550 when the icp card was configured at FFF560.
