Found these inside a non-working 71B

Reading a little more about the memory configuration you could have a RAM module that contains more than 32K bytes the 64K nibble limit is for an individual chip but a module could contain more than one chip, for instance the the 4K modules used for the base memory contain four 1K byte chips, so when they are polled by the configuration routine, they report 0000E 0000E 0000E 8000E where each group of 5 characters (nibbles) represents on chip in the module the "E" indicates it is a 2K nibble chip and the "8" in the last one reported indicates it is the last chip in the module. The OS as far as freeport and claimport are concerned still treat it as a single unit of memory. For a 64K module you could have it composed of two 32K chips and it would report as 00009 80009. The last nibble in the string indicates the size and is equal to 15-log2(size in nibbles). When you run the RAM diagnostics from the diagnostic module it reports for each chip in the module.
