Two small factual errors in the 34S article.
There are 112 registers -- X, Y, Z, T, L, I, A, B, C, D, J, K plus the numbered ones.
There are 104 flags -- A, B, C, D in addition to the numbered ones. Of these A is linked to an annunicator and D allows dangerous returns but B and C are altered by operations in integer mode but are freely usable in real mode.
A lessor point, I started coding the design before approaching Walter for assistance with the layout. The article implies (to me at least) that the reverse occurred. I won't deny that the outward appearance is now mostly Walter's doing.
