What is the Altair based on the paragraph?

Childhood friends Bill Gates and Paul Allen sought to make a business using their skills in computer programming.[12] In 1972, they founded Traf-O-Data, which sold a rudimentary computer to track and analyze automobile traffic data. Gates enrolled at Harvard University while Allen pursued a degree in computer science at Washington State University, though he later dropped out to work at Honeywell.[13] The January 1975 issue of Popular Electronics featured Micro Instrumentation and Telemetry Systems's (MITS) Altair 8800 microcomputer,[14] which inspired Allen to suggest that they could program a BASIC interpreter for the device. Gates called MITS and claimed that he had a working interpreter, and MITS requested a demonstration. Allen worked on a simulator for the Altair while Gates developed the interpreter, and it worked flawlessly when they demonstrated it to MITS in March 1975 in Albuquerque, New Mexico. MITS agreed to distribute it, marketing it as Altair BASIC.[11]: 108, 112–114  Gates and Allen established Microsoft on April 4, 1975, with Gates as CEO,[15] and Allen suggested the name "Micro-Soft", short for micro-computer software.[16][17] In August 1977, the company formed an agreement with ASCII Magazine in Japan, resulting in its first international office of ASCII Microsoft.[18] Microsoft moved its headquarters to Bellevue, Washington, in January 1979.[15]

The Altair as mentioned in the paragraph was a microcomputer developed by Micro Instrumentation and Telemetry Systems's (MITS). Its official name was the "Altair 8800 microcomputer". Altair BASIC was an interpreter that Bill Gates developed and demonstrated to MITS in March 1975 in Albuquerque, New Mexico. Paul Allen also worked on a simulator for the Altair.
