The following list describes the 8809 Magnetic Tape Unit models:
• Model 1 A attaches only to and has its adapter in an 8101 or an 8140 Model BXX.
• Model 18 attaches to either the 8130, 8140, or 8101. It has its own adapter, permits attachment of up to three more 8809s, and provides power for any 8809 Model 2 attached to it.
• Model 2 attaches to all other 8809 models. It can only be the second or fourth drive because it has no logic power source, and receives power either from Model 1 A, 1 B, or 3. It does, however, provide logic signal regeneration for the third drive, if attached.
• Model 3 attaches only_ to the Model 2, has its own power, and provides logic signal and power regeneration to the fourth drive, if attached.
CP160 8100 System Hardware Maximums and Restrictions
8130 Hardware Maximums. The 8130 Processor can have an attached maximum of two 8101 Storage and Input/Output Units and four 8809 Magnetic Tape Units. The 8101s connect to the 8130, while the 8809s can connect to either the 8130 or the 8101. With the System Expansion Feature, the maximum number of communications ports (FACs) permitted on an 8100 with an 8130 Processor is 14; six reside in the 8130 and eight in the 8101 (s).
Refer to the last paragraph for loop maximums and restrictions.
8140 Hardware Maximums. The 8140 Processor can have an attached maximum of four 8101 Storage and Input/Output Units and four 8809 Magnetic Tape Units. The 8101s connect to the 8140, while the 8809s can connect to either the 8140 or 8101.
Because of physical board limitations, the number of communications ports (FACs) available on the 8140 depends on processor model and installed features.
• 8140 Models A31-A34 have a three-port maximum, but capability for only two second lobe adapters.
• 8140 Models A41-A44 have a two-port maximum, capability for two second lobe adapters, but no ports available when having the expanded function panel.
• 8140 Models A5X-A7X have no ports available.
• 8140 Models BXX have a 12-port maximum, but capability for only three second lobe adapters.
• One diskette adapter and drive
• Two disk adapters and drives
• One tape adapter, which permits attachment of one 8809 Model 1A drive.
• One display/printer adapter.
• Up to 12 data link attachments, but only eight if display/printer or tape is installed.
Refer to the last paragraph for loop maximums and restrictions.
8101 Hardware Maximums. The following describes the 8101 hardware limitations on an 8100 system:
• Two 8101s can be installed on an 8130, but only one can have FACs.
• Four 8101s can be installed on an 8140, but only two can have FACs.
• If the system has an 8809 Model 1 B, an 8130 can have only one 8101 and an 8140 can have only three.
SY27-2521-3
Each 8101 can have:
• One diskette adapter and drive (Models A 10, A 11, A 13, or A20)
• One disk adapter and drive (Models A 11, A 13, or A23)
• Two disk adapters and two drives (Model A25)
• One tape adapter, which permits attachment of one 8809 Model 1 A drive.
• One display/printer adapter.
• Up to eight data link attachments, but only four if the display/printer adapter is installed.
Refer to the last paragraph for loop maximums and restrictions.
8809 Hardware Maximums. The following describes the 8809 hardware limitations on an 8100 system:
• Only one 8809 Model 1 A, or one 8809 Model 1 B.
• Three additional 8809s; two 8809 Model 2s and one 8809 Model 3.
Communications Maximums and Restrictions. The following describes the communica-tions port (FAC) maximums on an 8100 system:
• An 8130 can have up to 14 FACs.
• An 8140 can have either 16, 18, or 19 FACs, depending on model. (See "8140 Hardware Maximums").
Loop Maximums and Restrictions. The following restrictions apply to each 9600 bps or 38.4K bps loop on an 8100:
• 9600 bps loop
- 8 loop wiring concentrators 64 loop station connectors
80 I /O devices, when using a second lobe feature
• 38.4K bps loop
- 4 loop wiring concentrators 32 loop station connectors
40 1/0 devices, when using a second lobe feature.
The total number of attachable devices and loops supported by an 8100 is also affected by program limitations and performance considerations.

CP170 8100 System Logic Card Descriptions
The following briefly describes the logic cards used in the 8100. If the cards are not present in all three machine types, it is so noted. The pseudo number designations are indicated in parentheses.
• BOP Adapter Card (8130 and 8140 only): A 4-wide by 3-high FRU (018-81 card) that mounts on the 018 gate. It permits panel information transfer between the panel and the processor and PSCF, and also provides the logical signal attachment for the MD.
• Processor Instruction/Execution Cards (8U1-BU9): In the 8130 and 8140 nine different cards, each 4-wide by 3-high, that provide processor functions for the 8130/8140, and are used for:
- Instruction execution.
- Processor addressing capability and to permit the addition of the storage expansion
- Processor addressing capability and to permit the addition of the storage expansion
