The processor performed 36-bit single precision floating point arithmetic in hardware, but did not implement double precision floating point. The Case 1107 was immortalised by being included by Case alumnus Donald Knuth in the calculation of the decimal representation of the computer in. It was the largest, and final, member of the 1100 Series, and was the only system to be liquid-cooled. This also results in four unassigned accumulators A15+1. The keypunch room was on the near side of the left face of the building in this view, and the 1107 occupied the far half of the ground floor.

The core memory was available in 16,384 36-bit words in a single bank; or in increments of 16,384 words to a maximum of 65,536 words in two separately accessed banks. . The processor could have up to 16 channels for peripherals. The machine's registers were stored in 128 words of , a faster form of magnetic storage. These registers include both user and executive copies of the A, X, R, and J registers and many special function executive registers. When the predictions proved true and Eisenhower won a landslide within 1% of the initial prediction, Charles Collingwood, the on-air announcer, embarrassingly announced that they had covered up the earlier prediction.

Interviewees include ; ; ; ; and. The two 18-bit base registers one for instruction storage and one for data storage permitted dynamic relocation: as a program got swapped in and out of main memory, its instructions and data could be placed anywhere each time it got reloaded. A series of machines based on the same basic design followed, and were sold into the 1960s before being replaced by the similar-in-name-only family. The system also included a System Support Processor for diagnostic testing and system console support. A Few Good Men From Univac. 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.

When the predictions proved true and Eisenhower won a landslide within 1% of the initial prediction, Charles Collingwood, the on-air announcer, embarrassingly announced that they had covered up the earlier prediction. Instead they showed some staged theatrics that suggested the computer was not responsive, and announced it was predicting 8-7 odds for an Eisenhower win the actual prediction was 100-1. The 128 word thin film memory general register stack 16 each arithmetic, index, and repeat with a few in common had a 300 nanosecond access time with a complete cycle time of 600 nanoseconds. Purchased Components group was in Blue Bell. Some models of the 1108 implemented the ability to divide words into four nine-bit bytes, allowing use of characters. 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 two 18-bit base registers one for instruction storage and one for data storage permitted dynamic relocation: as a program got swapped in and out of main memory, its instructions and data could be placed anywhere each time it got reloaded. Six cycles of thin film memory per core memory cycle and fast adder circuitry permitted memory address indexing within the current instruction core memory cycle and also modification of the index value the signed upper 18 bits were added to the lower 18 bits in the specified index register 16 were available. The was introduced in 1981. Each memory cabinet contained eight independent 8K plated wire memory modules, or 64K for the entire cabinet. In addition to faster components, two significant design improvements were incorporated: base registers and additional hardware instructions. The largest configuration, 6x4 was only used by.
