Line 120: The absence of a submodel comprising a word-processing card and an amount of RAM of 32KB is due that IBM set the specifications for the word processing units with a minimum of 64KB. The submodel must be determined not by the number written at the rear plate but by observing the features of the machine, as some plates don't have the submodel written or have dummy values. By late 1982, most submodels with 32KB and 31SD floppy drives had been withdrawn from the market.<ref>https://archive.org/details/bitsavers_ibmserviceceForConsultants198210_13344165/page/n69/mode/2up</ref> == Hardware Description ==
