Depends on how you want them to be compatible.
The National Computer Center of Nepal had an IBM 1401 at least several years before 1978. It was use for many purposes including census and Royal Nepal Airlines. It was certainly the first large computer used there.
None. The Harvard Mark 1 ASCC (IBM Automatic Sequence Controlled Calculator) was an electromechanical computer built for Harvard by IBM's Endicott NY facility in 1944. It was constructed from 765,000 components which included switches, relays, motors, rotating shafts, and clutches. It contained no vacuum tubes.The Harvard Mark III ADEC (Aiken Dahlgren Electronic Calculator) was the first computer to use vacuum tubes. It was built at Harvard in 1949 using 5000 vacuum tubes and 1500 crystal diodes, along with electromechanical components. The Harvard Mark IV, built in 1952, was the first fully electronic design.
The IBM 7094 computer did not use a microprocessor; instead, it was based on transistor technology and utilized a series of integrated circuits. The 7094 was an advancement of the IBM 7090 and featured a more powerful instruction set and enhanced capabilities for scientific and engineering computations. It was introduced in 1962 and operated using a 27-bit word length.
The IBM 5150 is considered the first personal computer for home use. It was introduced to the public in August of 1981.

dell i thinkMost businesses use IBM machines
Yes, if you are using IBM specific components (Processor, RAM, etc.) they will most likely not work seemlessly in another motherboard.

The computer components in the Hubble telescope were custom-designed by IBM. It would be difficult to compare it to any consumer computer system.

IBM makes fantastic servers for the household. They are extremely reliable and trustworthy.

The first version of FORTRAN, developed in the 1950s by IBM, was not sold as a commercial product. Instead, it was provided to customers as part of IBM's service offerings associated with their hardware, specifically the IBM 704 computer. As a result, there was no specific sale price for FORTRAN itself, as it was bundled with the use of IBM's systems.
The term "PC," short for "personal computer," gained popularity in the early 1980s, largely due to IBM's introduction of the IBM PC in 1981. While the concept of a personal computer existed before IBM's model, the widespread adoption of the term can be attributed to IBM's marketing efforts, which helped define and standardize the category of personal computing for consumers. The term itself was in use prior to IBM's launch, but their product solidified its common usage.

Computer companies that are outsourcing to China at this time include IBM, Sun Microsytems and Dell. Another company that outsources to China is Modus Media.
