Forth-41

[coniglius]

Thanks for the quick response dmh. Yes, that's the link I got the FORTH 41+ module from. I tried to extrapolate the steps you mentioned in your video for loading it onto a 41CV to loading it on a DM41X. Maybe I did that incorrectly. Here's how I understood it and what I did (I'm also using latest v2.1 firmare on my DM41X):

1. Need FORTH41+ module in Port 1, extended functions in Port 2, extended memory in Port 3 and 4. I did this by copying the FORTH.MOD (from link above), the EXT-FUNS.MOD, and the EXT-MEM.MOD (both from hp41DOTorg/mod/) into the /MODS directory on the DM41X. Then adding them to flash and "plugging" them in under the Manage Modules in Flash on the DM41X. Doing this twice for the EXT-MEM.MOD (is it necessary to do that twice?). This gave me 4 active modules representing the 4 mentioned above (2x EXT-MEM. They're represented in the Active Modules list as (ellipses for brevity):

Extended Functions... MOD 1P
Extended Memory... MOD 0P
Extended Memory... MOD 0P
FORTH 41+ MOD 2P

Next I ran:

2. XEQ SIZE 010

3. XEQ FORTH

Code:

OK
DECIMAL
OK
5
OK: ( so yes I do get the colon until it errors/beeps as I'd previously mentioned )
.
5 OK
: STAR 42 EMIT ;
OK
STAR ( beeps )
STAR ( STAR remains in the editor and need to use repeated <- to delete, then R/S )
OK
5
OK ( note that I now no longer get a colon after OK when adding to the stack proceeding the "beep" error from executing STAR )
BYE
OK ( note here that BYE does not work, I get OK )

At this point, I have to hit ON/ON to power off and back on again and the behavior of FORTH will go back to normal where I can enter numbers on the stack and get "OK:", type "BYE" to exit etc. but I still will not be able to execute any words I've defined.

Did you use the FORTH-41 ROM from the article here?

If you are not getting OK: (with the colon) when putting numbers on the stack then you are probably running the older/original version.

Also, did you do SIZE 010 before running FORTH for the first time so it has enough buffer space?

I have FORTH-41 running on a 41CV and DM41X (as per the video). DM41X is running the latest firmware.

Let me know how you go, happy to compare my configs with screenshots etc if required.
