Quote:Enter in programs, make assignments, save to XM
Enter "OKALL" into Alpha
SF 1
The first thing I notice here is that the display does not show 1FF but only 800>1FE. So I must be doing something wrong as it seems to only save the MM state of the machine. Any tips?

Second, when I want to retrieve the state, I do
Quote:Enter "OKALL" into Alpha
SF 1
Again, the program only shows '1FE' but not '1FF' which at this point is expected. However all I get is a "Memory Lost" with no content in my memory.

Please tell me what I am doing wroing.

@PeterP - Check the manual on pp. 55-56. While it says that it requires a V3/V4 board, I'm not sure if V5 is compatible as well (it did not exist when the manual was released).

1FE is the Flash Page that RAM page 800 is written-to, likewise with RAM page 804 written to 1FF. The FOCAL code on p. 56 shows this.
