[[File:Altair 8800b Computer Front.jpg|thumb|right| Many companies made boards that could plug into the Altair / S-100 bus.]]

Owners of mainframe systems and minicomputers could purchase additional memory, interface boards and peripherals from third party suppliers; so it was predictable that owners of the Altair 8800 computer would do the same. MITS's delays in delivery of systems and accessories accelerated the formation of Altair compatible suppliers. The first ones started appearing in mid-1975 and by July 1976 complete computers systems were readily available.<ref name = "Byte July 1976">{{cite journal | journal = Byte | volume = 1 | issue = 11 | title= Advertisements | publisher = Byte Publications | location = Peterborough NH | date = July 1976}} Numerous advertisers in the issue claim Altair compatibility.</ref> The technical manuals for the Altair 8800 provided electrical schematics of the 100 pin computer bus allowing others to design compatible boards. There was not a proper technical standard at the time and some "compatible" boards did not work with other "compatible" boards. Later, the industry developed the [[S-100 bus]] standard.<ref name = "S100 Bus">{{cite journal | last = Morrow | first = George | author-link = George Morrow (computers) |author2=Howard Fullmer | title = Microsystems Proposed Standard for the S-100 Bus Preliminary Specification, IEEE Task 696.1/D2 | journal = Computer | volume = 11 | issue = 5 | pages = 84–90 | publisher = IEEE | date = May 1978 | doi = 10.1109/C-M.1978.218190| s2cid = 2023052 }}</ref>
