RE: Found these inside a non-working 71B
In the document of the proceeding of the 1985 HHC Atlanta conference there is an article written by Jim De Arras who appears to have been from Hand Held Products and he states that they originally made 64K memory modules, but ran into a bug in the original OS. What they found was that when freeported a 64K module when there is no hard configured module such as hard FORTH installed the free space routine would report no free memory because of the way the code worked that checked for space. All of the gory details are in that document. It is possible this may have been fixed in later levels of OS. So this would suggest that you can configure 64K of RAM in a single module. After reading this I went and looked at the IDS where they describe the memory configuration process and the table in that section indicates that the maximum size for a RAM module is 64K nibbles or 32K bytes.
