I was going to install it till a house fire melted the 820. The original 820 came with dual 8" floppies or an 8" floppy and an 8" harddrive and ran CPM. It was a spendy little computer for its time. Then they fit Dual 5 1/4" floppies in an external case, came out with a low profile keyboard and the add on 8086 Board. They called it the Xerox 820II-8/16. IIRC the design was taken from the Z80 Big Board which was a popular kit at the time. It was mounted flat, underneath the CRT and looked much like a terminal. At the time the IBM PC came out the Xerox design was hopelessly outdated. They redesigned the case to a rectangular shape with a separate monitor ala the IBM PC. They used dual 5 1/2" half height floppies oriented horizontally. I never saw an actual one but IIRC they used the same Big Board coupled with the 8086 board that was in the 820 and sold it as the Xerox 8/16. It ran CPM, CPM-86 and MS-DOS ( IIRC to 2.11). However it was not IBM Compatible, and did not have IBM graphics. By the time it was ready the bottom had fallen out of the crossover market. I don't think Xerox sold any commercially. A liquidation company sold the remainder for about three years. I doubt they sold many, I bet most were scrapped for the drives. The Xerox 820 II was my second computer system and still one of my favorites. (The first was State Surplus Litton 1251 that I bought for $25.00) I have had almost all of the various models of the 820 go through my hands over the years. Besides my original melted one I still have another packed away with all it's SW. Someday it will run again. Paxton Astoria, OR
