Yes. I have no special purpose registers that you can directly access. The stack top register you have to use an instruction to actually look at or change.
I can link to my horrible google sheets for my Instruction set if that helps at all. But basically all arithmetic logic types of instructions work directly on registers and can not touch the ram. You have to load and store from ram into the registers to access anything.
