In the version of "Jipi and the Paranoid Chip" that appears online, there's a note at the top: "(excerpt as appeared in Forbes, July 7, 1997)." Was the version that appeared in Forbes an excerpt of a longer version? Has the story ever been published anywhere excerpt Forbes?
The only place I can find any published information for "Jipi and the Paranoid chip" (AKA "Jipi's Day at the Office") is in Forbes Magazine with various copies of the same length story being found on the internet
If a longer version does exist, it's never been officially published. The copyright for the story is held by Forbes and in his book "Some Remarks", Neal refers to 'Jipi and the Paranoid Chip' as being
"extraordinarily ponderous and labored upon rereading and so has been left out [of future publications of his short fiction]".
