There was so much stuff to cover but there's a slight mention saying " had to add the LOADM and STOREM instructions as these handle the spilling of local registers to memory when the register stack is full" I can add an extra explanation there.
It was more an expression of surprise than anything else. The defining feature of the 29K, when I was introduced to it at least, was what appeared to be an enormous register set and the way of dealing with the stack better than the SPARC equivalents.
The fact you got this stuff working at all is completely mind bending.
