Somehow bit slice abd bubble memories are cataloged side by side in my brain. https://en.wikipedia.org/wiki/IBM_PALM_processor There is another golden oldie. The 5120 was a strange beast, selectable for either BASIC or APL. It's successor, the System/23, had an 8085 rather than IBM's homebrew but had a similar look. Familiarity with the 8085 was one of the factors for using the 8088. What i never could figure out is the 5100, 5120, and 5120 were all the PALM, whue the System/23 went to 53xx. Then they went back to 5150 for the PC that had absolutely nothing in common with the 5120.
