- UNIVAC_1107 abstract "The UNIVAC 1107 was the first member of Sperry Rand's UNIVAC 1100 series of computers, introduced in October 1962. It was also known as the Thin Film Computer because of its use of thin film memory for its register storage. 36 systems were sold.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. With a cycle time of 4 microseconds, the effective cycle time was 2 microseconds when instruction and data accesses overlapped in two banks.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. 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 16 I/O channels also used thin film memory locations for direct to memory I/O memory location registers. Programs could not be executed from unused thin film memory locations.Both UNISERVO IIA and UNISERVO III tape drives were supported, both of which could use either metallic (UNIVAC I) or mylar tape.The FH880 drum was also supported as a spooling and file storage media. Spinning at 1800 rpm it stored approximately 300,000 36 bit words.Univac provided a batch operating system, EXEC I. Computer Sciences Corporation was contracted to provide a powerful optimizing Fortran IV compiler, an assembler named SLEUTH with sophisticated macro capabilities, and a very flexible linking loader.".
