Past
There have been many 3rd party ram modules over the years. Here are just a few examples.
| NEC |  |
| Purple Computing 1983 |  |
| Purple Computing 1985 |  |
Other
There are also ram expansion accessories that connect to the system bus and either add extra banks of 32k to the internal ram, or replace the internal ram. These aren't normal ram modules that plug into the normal ram sockets. They plug in to the system bus cnnector and provide the entire 32K address space at once from there, as if all ram sockets were filled.
