 instruction type.  All numbers were scaled to less than 1 in absolute value.  It had built-in automatic decimal-to-binary and binary-to-decimal number conversion that worked at 500 words/second.  The system clock ran at 1 MHz.  Addition operations took, on average, 850 microseconds, whereas multiplications and divisions took 3300 microseconds.

The system used both a 512-word mercury delay line and magnetic tape for memory, and for data input, the system was equipped to process Flexowriter paper tape (at a rate of 1 word/second), magnetic wire (40 words/second), Raytheon magnetic tape (250 words/second), and paper tape (150 characters/second).  The system could output to Flexowriter paper tape (at a rate of 1 word/second), magnetic wire (20 words/second), or paper tape (180 characters/second).

Use
All programming for FLAC was written in machine language, as the machine lacked any high-level language, assembler or compiler.  Typical programs transformed missile tracking data from missile tests, recorded to rolls of seven-hole Flexowriter punched paper tape, cartridges of magnetic wire, and reels of magnetic tape, into missile trajectory and performance data.

During its service life, FLAC was operated by an engineer or technician and one operator for two 8-hour shifts.  It had an operational uptime of about 90%.

Other features of the computer included insertion of short words, automatic truncation, automatic zero suppression, automatic scaling, and printed format control.

FLAC I was housed in a three-story wooden building south of the cafeteria at PAFB, while the two FLAC II systems were built in the South Wing of the Tech Lab in summer and fall of 1956.  FLAC II abandoned mercury delay line memory in favor of a faster and more versatile 4096-word magnetic core memory.

The FLAC machines' service life ended in 1960, whereupon they were replaced by IBM 709 scientific computers.

Some of the USAF personnel involved in the construction of FLAC, including Thomas G. Holmes, Charlie West, John MacNeill, Jim Bellinger, Steve Batchelor and Harlan Manweiler, together with Jim Allen, later went on to form Soroban Engineering, Inc. in Melbourne, Florida.
