Cool place like EEVBlog, but for software / programming?
mkiijam:
Title says it all. I have a CF card that I need to read and change code on, nothing illegal, just lost access codes. My thought was to copy the data and dig in, but I'm not a software guy.

Sorry, but the title does not help with your question.
Provide specifications about the CF card. Do you have a card reader connected to your computer? What type of operating system are you using? How much data are you talking about? Is it readable text or is it encoded binary?
Try to be more specific when asking a question.
Like eti suggested, you can start a new thread in the programming section but use a title like "Need to retrieve data from a CF card" and word your question such that it provides the needed information.
rstofer:
If I wanted to dump a CF, I would probably use the Linux 'dd' command. There are places where Linux shines and this is one of them.
The 'dd' command will allow you to copy, byte by byte, from the CF to your hard drive. It will also copy an image from hard drive to CF.

Title does say it all cause I didn't know there were cool software / programming dudes(ettes) here! Yay!
Okay, I don't got nothing yet. A reader makes perfect sense. I looked on eBay and Amazon and haven't a clue of anything trust worthy. Recommendations on brand / model?
1. Windows 10, but I have many computers I could load any OS on.
2. It's a 32Mb card.
3. At this point I have no idea how the data is stored.
Here are some more details and then maybe I should start a new post in the programming section(?)
a. This hardware is an automated industrial processor that no longer has any support.
b. It has a touch screen GUI that is asking for a "access code" that is numerical 0-9. It looks like could any length up to 7 digits. i.e. 01 is just as valid as 001, 0001 as an attempt. Unlike some "PIN" numbers that require 4 digits as a minimum and maximum.
c. Some digging into some available history reveals the previously written automation protocol, including the user password / access code is stored on a CF card. I opened it to indeed find a card.
d. It does have a way, through dip switches, to erase any user loaded software and return to factory settings, but I need to run the unit AS IS before I do that, hence wanting to get pass its password block.
