Even just restricting discussion to the first season, before the same people apparently not only clone the PC but also create (facsimiles of) Sierra Online, McAffee, Netscape and Yahoo, she's not based on anybody real.
In real life the source code for the IBM BIOS was printed in the back of the manual. There was no Gordon inexplicably hand transcribing the assembly address by address. There was one team of technical writers that read the manual and the source and provided detailed specifications. Those specifications were handed to the legal team. The legal team handed them to a team of engineers. The engineers implemented them.
So she's a compound of a team, and I think the strange subplot about the friendly OS is completely fictitious; probably groundwork for Joe's discovery of the Apple Macintosh (i.e. that he was not a leader but a follower), and his ensuing crisis.
The people usually lauded from Compaq are the management, for successful execution of the machine; not any star engineer. But that sounds like boring television.
