DSA (BBBBCcbb) Unit address
The disk unit has the xy0100FF (where x is the same as the first character of the
same DSA as the IOP xFFFFFFF IOA Unit Address and y is I/O bus 0, 1 or 2. Storage
controlling the Storage IOA I/O buses begin with 0 and are numbered from the tailstock
IOA. toward the middle of the card. Find the storage IOA with the
same DSA and xFFFFFFF address, then trace the I/O bus cable
to determine if the position is D09 or D15.)
The disk unit has the xy0200FF (where x is the same as the first character of the
same DSA as the IOP xFFFFFFF IOA Unit Address and y is I/O bus 0, 1 or 2. Storage
controlling the Storage IOA I/O buses begin with 0 and are numbered from the tailstock
IOA. toward the middle of the card. Find the storage IOA with the
same DSA and xFFFFFFF address, then trace the I/O bus cable
to determine if the position is D10 or D16.)
The disk unit has the xy0300FF (where x is the same as the first character of the
same DSA as the IOP xFFFFFFF IOA Unit Address and y is I/O bus 0, 1 or 2. Storage
controlling the Storage IOA I/O buses begin with 0 and are numbered from the tailstock
IOA. toward the middle of the card. Find the storage IOA with the
same DSA and xFFFFFFF address, then trace the I/O bus cable
to determine if the position is D11 or D17.)
The disk unit has the xy0400FF (where x is the same as the first character of the
same DSA as the IOP xFFFFFFF IOA Unit Address and y is I/O bus 0, 1 or 2. Storage
controlling the Storage IOA I/O buses begin with 0 and are numbered from the tailstock
IOA. toward the middle of the card. Find the storage IOA with the
same DSA and xFFFFFFF address, then trace the I/O bus cable
to determine if the position is D12 or D18.)
The disk unit has the xy0E00FF (where x is the same as the first character of the
same DSA as the IOP xFFFFFFF IOA Unit Address and y is I/O bus 0, 1 or 2. Storage
controlling the Storage IOA I/O buses begin with 0 and are numbered from the tailstock
IOA. toward the middle of the card. Find the storage IOA with the
same DSA and xFFFFFFF address, then trace the I/O bus cable
to determine if the position is D13 or D19.)
