Hello Erwin,

While you are waiting for the configuration setup, I am giving you some home work to do

This home work will do bank switching between the Finance 16KB ROM and the CurveFit 32KB ROM.

Loading ROM images into FRAM memory

1. POKE "2C000","00000000000000000000000000000000" [ENDLINE] // to start with a clean sheet
2. // power cycle
3. MEM [ENDLINE] // you should have ~16.5KB of RAM
4. POKE "2C000","A3" [ENDLINE] // setup bank #1 -> Chip #0 with FRAM-Block #3 as 16KB RAM
5. // power cycle
6. CLAIM :PORT(5) [ENDLINE] // just in case the port was freed by a previous configuration
7. MEM [ENDLINE] // you should have ~32.5KB of RAM
8. FREE :PORT(5) [ENDLINE] // create the space to received the 16KB Finance ROM
9. MEM [ENDLINE] // you should have ~16.5KB of RAM
10. SHOW PORT [ENDLINE] // you should see -> Port: 5 / Size: 16384 / Type:1 IRAM
11. // load the FRAMTK LIF image into pyILPER or ILPER
12. COPY ROMCOPY:TAPE [ENDLINE] // load ROMCOPY LEX file into main memory
13. // load the FINANCE LIF image into pyILPER or ILPER
14. ROMCOPY FINANCE:TAPE TO :PORT(5) [ENDLINE] // load FINANCE 16KB ROM image into port 5
15. CAT :PORT(5) [ENDLINE] // show port 5 Finance ROM content
16. POKE "2C000","00" [ENDLINE] // remove Chip #0 configuration, this step prevent a computer freeze or a memory lost
17. // power cycle
18. POKE "2C000","94" [ENDLINE] // setup bank #2 -> Chip #0 with FRAM-Block #4 as 32KB RAM
19. // power cycle
20. CLAIM :PORT(5) [ENDLINE] // just in case the port was freed by a previous configuration
21. MEM [ENDLINE] // you should have ~48.5KB of RAM
22. FREE :PORT(5) [ENDLINE] // create the space to received the 32KB CurveFit ROM
23. MEM [ENDLINE] // you should have ~16.5KB of RAM
24. SHOW PORT [ENDLINE] // you should see -> Port: 5 / Size: 32768 / Type:1 IRAM
25. // load the CURVEFIT LIF image into pyILPER or ILPER
26. ROMCOPY CURVEFIT:TAPE TO :PORT(5) [ENDLINE] // load CURVEFIT 32KB ROM image into port 5
27. CAT :PORT(5) [ENDLINE] // show port 5 CurveFit ROM content
    

Activating the 16KB Finance ROM in Bank 1 (Chip #0 with FRAM-Block #3)

1. POKE "2C000","00" [ENDLINE] // remove Chip #0 configuration, this step prevent a computer freeze or a memory lost
2. // power cycle
3. POKE "2C000","A3" [ENDLINE] // activating bank #1 as IRAM
   or
   POKE "2C000","E3" [ENDLINE] // activating bank #1 as ROM
4. // power cycle
5. CAT :PORT(5) [ENDLINE] // show port 5 Finance ROM content
   

Activating the 32KB CurveFit ROM in Bank 2 (Chip #0 with FRAM-Block #4)

1. POKE "2C000","00" [ENDLINE] // remove Chip #0 configuration, this step prevent a computer freeze or a memory lost
2. // power cycle
3. POKE "2C000","94" [ENDLINE] // activating bank #2 as IRAM
   or
   POKE "2C000","D4" [ENDLINE] // activating bank #2 as ROM
4. // power cycle
5. CAT :PORT(5) [ENDLINE] // show port 5 CurveFit ROM content
   

With the above steps, reading carefully (multiple times) Hans manual, Dave/Robert/me how-to's and some experiment you should be able to try other configurations by yourself.
