Not so the MMU registers/41CL RAM, so it's going to take some futzing (that's a technical term :-) ) with the data. Geir Isene had to handle this when he did the HP-IL update stuff, so I would look at that code as a starting point.POP!!! The 10-bit is the instruction width of the Nut CPU, the addressing (PC) is 16-bit wide (64K or 16 pages of 4K). |
