Description
The total production run of the 1130 has been estimated at 10,000. The 1130 holds a place in computing history because it (and its non-IBM clones) gave many people their first direct interaction with a computer. Its price-performance ratio was good and it notably included inexpensive, removable disk storage, with reliable, easy-to-use software that supported several high-level languages. The low price (from around $32,000 or $41,000 with disk drive) and well-balanced feature set enabled interactive "open shop" program development.
The IBM 1130 used System/360 electronics packaging called Solid Logic Technology (SLT) and had a 16-bit binary architecture, as did later minicomputers like the PDP-11 and Data General Nova.
The address space was 15 bits, limiting the 1130 to 32,768 16-bit words (65,536 bytes) of memory. The 1130 used magnetic-core memory, which the processor addressed on word boundaries, using direct, indirect, and indexed addressing modes.

Famous quotes containing the word description:
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
