When Lisa arrived on the scene it caused a lot of excitment. Apple's stock jumped from $24 a share to over $60 in the space of a few months. But despite this Lisa did not sell well. The high price and slow speed of the original Lisa held back sales. Apple's stock dropped back to $17 per share.
Another problem was the 5.25 inch floppy drives. The Lisa's floppy drives were made by Apple and were prone to problems. Apple has never made a floppy drive since (Mac floppy drives are made by Sony).
Press stories about Apple planning a smaller, cheaper "baby Lisa" (released as the Macintosh) didn't help sales either.
In January 1985 Apple re-badged Lisa as the Macintosh XL. Within a few months, April 1985, the Mac XL was discontinued. Sun Remarketing bought 5,000 Lisas and sold them for several years.
