A number of computer historians have pointed out that the first example of "doing an Osborne" probably originated with North Star Computers, Inc back in 1978, five years before Osborne shuffled off its mortal coil.
North Star was an early CP/M personal computer vendor. In 1978, North Star Computers announced a new version of its floppy disk controller at the same price, but with double the capacity of the old controller. When sales of the old controller decreased, the company nearly went out of business.
