The Macintosh SE/30 was new the same year Apple bulldozed Bob's old (would be) Lisa Professional stock: 1989. At this point they are both running variations of System 6 and (from this article) it sounds like Sun Remarketing is selling to a lot of businesses, the market Apple wants to grow. It's easy for me to see the Lisa Pro as real competition for the SE/30, they might be far apart in terms of hardware but to customers they probably looked very similar, particularly customers focused on word processing and spreadsheets. From then on, it seemed like Apple was selling that machine forever. That SE/30 was improved a bit and branded the Classic II in 1991, the next year old stock was re-branded as the Performa 200 and they kept on selling that thing, AFAICT, until they sold them all. I remember seeing them in Sears as late as 1994 sitting right next to PowerPC Performa models.
