If the RAM appears in a ROM socket then to write to it IIRC you load the
image into normal RAM, select the ROM number of the sideways RAM and
then copy the data to the ROM.

Thats how I got data into a sideways RAM i fitted to my electron's AP3
anyway.

You could try to get hold of RLoad, which IIRC came with the SJ sideways
RAM, we used that at school to load images into a number of sideways RAM
systems.
