It has allthe speed and operating features found only in much more expensiveequipment, including instructions that facilitate floating-point and multiprecisionoperations. An evaluation of the 920's unequalled performance-per-dollar<strong>ca</strong>pabilities <strong>ca</strong>n be made by comparing the followingcharacteristics with any presently available digital computer:TYPE: Single address with indexing and indirect addressing • Binary •Core Memory • Solid State • Instructions for facilitating floating-pointand multi-precision operations. Parity checking on Input/Output andMemory Operations • Programmed OperatorMEMORY: Coincident magnetic core • 4096 words expandable to 16,-384 words-all directly addressable. 24-bit word and parity.

Although its primary purpose is on-line control andreal time systems work, the 910 is useful as a general purpose scientificcomputer. The 910 is the first and only random access machine withbuffered input/output to be priced below $90,000. It operates directlywith all types of input/ output devices, including magnetic tape units,automatic typewriters, and analog-to-digital converters.TYPE: Single address with indexing and indirect addressing • Binary •Core Memory • Solid State • Parity checking on Input/Output andMemory Operations • Programmed OperatorMEMORY: Coincident magnetic core . 2048 words expandable to 16,384 words - all directly addressable . 24-bit word and parity.
