What are SIMMs?
> A SIMM, or single in-line memory module, is a type of memory module
> containing random access memory used in computers from the early
> 1980s to the late 1990s. It differs from a dual in-line memory
> module (DIMM), the most predominant form of memory module today, in
> that the contacts on a SIMM are redundant on both sides of the
> module. SIMMs were standardised under the JEDEC JESD-21C standard.
