I doubt it.  Storage costs and hassles would be immense. Given that few people kept old Apple 1&#x27;s around, as small as they are (which is why they sell so high at auction), I see no sense in preserving a mainframe, then or now.<p>I would guess that most surrendered mainframes (for the past decade or two) would be directly decommissioned, having no subsequent market warranting re-deployment.<p>Have you <i>been</i> in an old-school mainframe shop? I left that world in 1986 for the minis&#x2F;PCs&#x2F;UNIX world and didn&#x27;t follow the industry after that.  But at that time, a mainframe like an IBM 309x (successor to the 308x, which was the successor to the 3033, which was the successor to the 370 era) required huge, elevated, Halon-protected, chilled rooms, with banks of tape drives the size of a phone booth, hard drives the size of a small chest freezer, plus numerous large peripherals (printers, card readers, card punches, etc.), and an enormous power infrastructure.<p>Today, you now have more CPU power in your phone.<p>I <i>loved</i> operating mainframes alone - it was like being an orchestra conductor, except you could reboot a recalcitrant concertmaster.<p>It was typical of the mainframe world that machines were <i>leased</i> rather than owned.  I guess the owners would redeploy if there was any customer, otherwise decommission for parts&#x2F;scrap.  The hassle of transport&#x2F;exchange was huge.<p>BTW, anybody need 9-track reel tapes?  I have a few.
