The Datapoint 2200 had a built-in full keyboard, a built-in monochrome monitor (green) with 12 lines by 80 columns and two 47 characters per inch cassette drives with a capacity of 130 kB each .
Datapoint 2200 was designed as a versatile and economical computer for connecting to various computers, loading emulation programs from tape, whereas most terminals of the time were hardwired. The Datapoint 2200 had 8 KB of internal memory and used cassettes with a capacity of 130 KB to store information 1 . An 8-inch floppy disk drive then became available .
Datapoint 2200 has a different connection to computer history. The original design was to use a single-chip 8-bit microprocessor as the CPU instead of a TTL circuit module. In 1969, CTC commissioned Intel and Texas Instruments (TI) to develop the chip. TI couldn’t make a chip that works stably, so it got off on the way, but Intel completed it for the time being. However, its performance did not meet the requirements of CTC, so CTC was forced to manufacture it with a TTL circuit .
while Intel’s single-chip design was finally published in April 1972 under the name Intel 8008 . Nevertheless, the 8008 CPU is of pioneering importance
