Camintonn Memory
Overview
Camintonn made several memory modules for LSI-11 computers. Genuine DEC memory modules, with more than 256 KB onboard, are difficult to find and much more expensive than third-party modules. Configuration information on DEC modules, however, can be difficult to find.
The table below compares the different Camintonn modules.
