I only have experience with the Nova 4 Jr. CPU and Nova 3, both without the
Battery Backup, Memory Management or Multiple/Divide options. The Nova 4 Jr.
CPU had 64k byte of memory in the front left corner of the CPU pcb. It does
have the virtual terminal that connects to an external terminal. This
replaced the paddle switch functions of the Nova 3.

Subject: Nova 4/C Questions
I'm assessing a pair of Nova 4/C chassis that I have had for a few months.
One of the units has a CPU but no memory; the other has a MOS memory board
but no battery backup unit.
Can anyone tell me whether older Nova core memory is compatible with the
4/C processor (I suspect not), and whether the battery backup unit is
required for the memory to operate, or whether it was just sold as an
option ? I think the wiring is there for it in the chassis.
