8-bit acorn hardware • Re: Interesting problems with commands from a rom image in SWRAM on an Electron

***ANYTHING*** passed to code in a sideways bank - such as filing systems, utilities, OSWORDS, OSBYTE, etc. - has to have its control block in memory that is visible by ALL of the machine, ie, *NOT* in a sideways bank.
Since it's not always obvious which OS calls might get processed by a sideways ROM, would you extend that to say that one should never execute any OS call with a parameter block or other data in sideways memory? Are there any exceptions?
