Technical Description
The Datapoint 2200 had a built-in full-travel keyboard, a built-in 12-line, 80-column green screen monitor, and two cassette tape drives each with 130 KB capacity. Its size (approx. 2w×2d×1h ft) and shape (a box with protruding keyboard) approximated that of an IBM Selectric typewriter. Initially a Diablo 2.5 MB 2315-type removable cartridge hard disk drive was available, along with modems, several types of serial interface, parallel interface, printers and a punched card reader. Later, an 8-inch floppy disk drive was also made available, along with other, larger hard disk drives. An industry-compatible 7/9-track (user selectable) magnetic tape drive was available by 1975. In late 1977, Datapoint introduced ARCnet local area networking. The original Type 1 2200 shipped with 2 kilobytes of serial shift register main memory, expandable to 8K. The Type 2 2200 used denser 1 kbit RAM chips, giving it a default 4K of memory, expandable to 16K. Its starting price was around US$5,000, and a full 16K Type 2 2200 had a list price of just over $14,000. The 2200 models were succeeded by the 5500, 1100, 6600, 3800, 8800, etc.

Famous quotes containing the words technical and/or description:
“A technical objection is the first refuge of a scoundrel.”
—Heywood Broun (1888–1939)
“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)
