Changes
The iRAM expansion sits in the CPU socket and requires no additional soldering inside the CPC.
== Compatibility ==
So far no incompatibilities have been reported.
The first 512K of expansion RAM follow the [[Standard_Memory_Expansions#Standard_128K-512K_Expansions_.28dk.27tronics.2Fdobbertin-style.29|DK'Tronics addressing mode standard]], giving up to 576K of RAM to legacy software. More modern software that supports the [[Standard_Memory_Expansions#Extended_1M-4M_Expansions_.28RAM7.2FYarek-style.29|extended 1M-4M standard]] will be able to access all the provided RAM.
Unlike other RAM expansions the iRAM can be used in parallel to an external RAM expansion. The iRAM has priority over external RAM expansions and only requests above the iRAM memory limit will be passed to an external RAM expansion. External memory expansions that are smaller than the iRAM will be ignored. This is particularly helpful for external feature-expansions that also provide a RAM expansion. Those expansions usually cannot be connected in parallel to another (bigger) RAM expansion. E.g. DDI-5/6, ULIFAC and Pico CPC limit the CPC to the RAM provided by those expansions. A great use case is to put the ULIFAC in ROM board mode which limits the RAM to 192 or 256K - but with the iRAM installed the CPC still has access to the full RAM provided by the iRAM.
