the 1100/80 system could be expanded to a maximum of two CAUs, and two IOUs. A later version was expandable to four CAUs and four IOUs. The SIU control panel of the updated 1100/80 (pictured above) was able to logically and physically partition larger Multi-Processor configurations into completely independent systems, each with its separate Operating System. The CAU was capable of executing both 36-bit 1100 series instructions, and 30-bit 490 series instructions. The CAU contained the same basic register stack, in the first 128 words of addressable memory, as previous generations of 1100 Series machines, but since these registers were implemented with the same ECL chips as the rest of the system, the registers did not require parity to be generated/checked with each write/read. The IOU, or Input/Output Unit was modular in design and could be configured with different Channel Modules to support varying I/O requirements. The Word Channel Module included four 1100 Series (parallel) Word Channels. Block Multiplexer and Byte Channel Modules allowed direct connection of high-speed disk/tape systems, and low speed printers, etc. respectively. The Control/Maintenance Panel was now on the SIU, and provided a minimum of indicator/buttons since the system incorporated a mini-computer, based on the BC/7 (business computer) as a maintenance processor. This was used to load microcode, and for diagnostic purposes. The CAU, IOU, and SIU units were implemented using

allowed I/O operations to be independent from the compute operations, no longer "stealing" memory cycles from CAU(s). The IOAU included 8 (optionally 16 or 24) 1108/1106 compatible 36-bit Word Channels, and also included the Hardware Maintenance Panel. Pictures/illustrations of a 1110 system typical showed the IOAU Maintenance Panel, as the CAU cabinet had no indicator lights. The IOAU Maintenance Panel could display the various CAU registers from one or two associated CAU(s). The 1110 CAU also introduced an extension to the instruction set of 'Byte Instructions'. The major components of the 1110 system, the CAU, IOAU and Main Memory cabinets were designed using the same 55-pin high density card connectors, and machine wire wrapped backplane(s) as the 1108/1106. The discrete component logic used by the older systems was replaced by

981:, the 1108 had memory protection using two base and limit registers, with 512-word resolution. One was called the I-bank or instruction bank, and the other the D-bank or data bank. If the I-bank and D-bank of a program were put into different physical banks of memory, a 1/2 microsecond advantage accrued, called "alternate bank timing." The 1108 also introduced the Processor State Register, or PSR. In addition to controlling the Base Registers, it included various control "bits" that enabled the various Storage Protection features, allowed selection of either the User or Exec set of A, X & R registers, and enabled "Guard Mode" for user programs. Guard Mode prevented user programs from execution of Executive Only "privileged" instructions, and from accessing memory locations outside the program's allocated memory. 1106:. Like the 1108, it was multiprocessor capable, though it appears that it was never supplied with more than two CPUs, and did not support IOCs. In fact, the only difference between an 1108A CPU and an 1106 CPU was a couple of timing cards. In order to keep costs low, an 1106 CPU could be ordered with as few as four word channels. This meant that only three I/O channels were available for peripheral subsystems, as channel 15 (the highest-numbered channel) was always, in both 1106 and 1108 systems, dedicated to the operator's console. Early versions of the UNIVAC 1106 were simply half-speed UNIVAC 1108 systems. Later Sperry Univac used a different memory system which was inherently slower and cheaper than that of the UNIVAC 1108. Sperry Univac sold a total of 338 processors in 1106 systems. 20: 1143:. Each memory cabinet contained eight independent 8K plated-wire memory modules, or 64K for the entire cabinet. As with the 1108/1106, there was a maximum of four 64K cabinets per system. The 1110 also had 'Extended Memory' cabinets accessible in a 'daisy chain' arrangement to augment main storage. It was possible to utilize the 1108 64K core memory cabinets as Extended Storage, but in most systems utilized, the larger, less expensive 131K memory cabinets from the 1106 system. Up to eight Extended Memory cabinets were allowed, for a maximum of one million words of Extended Storage. An ESC (Extended Storage Controller) was required for each pair of memory cabinets to provide the physical connection, and address translation, from the 1110 CAUs and IOAU(s). 1286: 942: 1045:(FFT). At a simplified level, one of the 1108A CPUs would move data arrays into core memory, and send the UAP an instruction packet, containing the function to be executed, and the memory address(es) of the data array(s), across a standard I/O channel. The UAP would then perform the operation, totally independent of the CPU(s), and, when the operation was complete, "interrupt" the originating CPU via the I/O channel. A very small number of UAPs were built, for 1197: 2468: 1248:(ECL) on high density multi-layer PC boards. The ECL circuitry utilized DC voltages of +0 and -2 volts, with the CAU requiring four 50 amp -2 volt power supplies. Power was 400 Hz, to reduce large scale DC power supplies. The 400 Hz power was supplied by a motor/alternator, because even though solid state 400 Hz inverters were available, they were not considered reliable enough to meet the system uptime requirements. 1226:) Memory Cabinet. The allowed Main Storage to be expanded from maximum of 262K to a maximum of 524K. The Type 7030 Main Memory cabinet still contained eight separate Memory Modules, but they were now 16K (38-bit words, 36 Data and 2 Parity), instead of 8K each. The Type 7013 131K Core Memory Cabinet (originally used on the later 1106 Systems as Main Storage) was also replaced with a Solid-State Memory Cabinet, based on 1024:

path for each IOC. The memory was organized in physical banks of 65,536 words, with separate odd and even ports in each bank. The instruction set was very similar to that of the 1107, but included some additional instructions, including the "Test and Set" instruction for multiprocessor synchronization. Some models of the 1108 implemented the ability to divide words into four nine-bit bytes, allowing use of

It was fairly common to discount list prices for large and/or Government customers. 998:

more separate cabinet(s), and consisted of two separate 32K modules, for a total capacity of 64K 38-bit words (36-bits data and a Parity Bit for each 18-bit half-word). The basic cycle time of the core memory was 750 ns, and the supporting circuitry was implemented with the same circuit card/backplane technology as the 1108 CPU.

With everything busy, five activities could be going on at the same moment: three programs running in the CPUs and two input/output processes in the IOCs. One more instruction was incorporated: 1174:

in the system. The 1100/40 utilized a new Main Memory cabinet, replacing the 8K plated-wire memory modules with 16K static RAM modules (based on 1024x1-bit static RAM chips), for a total of 131K per cabinet. This allowed expansion of the Main Memory to a maximum of 524K. As with the 1110, the 1100/40

The 1108 CPU was, with the exception of the 128-word (200 octal) ICR (Integrated Control Register) stack, entirely implemented via discrete component logic cards, each with a 55-pin high density connector, which interfaced to a machine wire wrapped backplane. Additional hand

The 1100/80 introduced a high-speed cache memory – the SIU or Storage Interface Unit. The SIU contained either 8K, or (optionally) 16K 36-bit words of buffer memory, and was logically and physically positioned between the CAU(s)/IOU(s) and the (larger, slower) Main Memory units. The first version of

The UNIVAC 1110 had enhanced multiprocessing support: sixteen-way memory access allowed up to six CAUs (Command Arithmetic Unit, the new name for CPU and so called because the CAU no longer had any I/O capability) and four IOAUs (Input Output Access Units, the name for separate units which performed

In addition to faster components, two significant design improvements were incorporated: base registers and additional hardware instructions.

characters. Most 1108A configurations included one or two CPUs, each with eight or (optionally) 16 36-bit parallel I/O channels, and two or three 64K core memory cabinets. Three CPU systems, with four core memory cabinets were the exception due to cost considerations. The IOC was a separate cabinet

1023:

The 1108 II, or 1108A, was the first multiprocessor machine in the series, capable of expansion to three CPUs and two IOCs (Input/Output Control Units). To support this, it had up to 262,144 words (four cabinets) of eight-ported main memory: separate instruction and data paths for each CPU, and one
