Changes
/* Non-Standard Expansions */
* [[Otten & Fecht 1 MB RAM-Disc]] - Accessed through I/O ports (RAM is not mapped to memory)
* [[Vortex Expansions RAM card]] - an older expansion, uses 32K-banks, not compatible with the later standard
* [[Nova]] - Non-volatile 32KB RAM and RTC
== Expansions that are unknown how they work, and if they are standard or not ==
