Token decode

Chris9999

My shop was broken into and a computer stolen. This computer had a sx program that was not backed up.
I have the eeprom with the program in it. I can read the eprom code, but I was wondering if there is any source for reversing the token codes back to some sort of human readable text.
Thanks
Chris

You could probably get it back to assembler, but all the variable names, comments, etc. would be lost.
It probably won't be something you could modify any further anyway.
If you can read the code back you can make new chips if that is your goal.

Thanks for your comments,
That is my goal, to get it back to assembler without the variable names and comments.
It is just to get the aid in re-writing it.
My question is now is how or who?

read the code back, then use angelica, a very good disassembler for the SX. It will rename everything, but bring it back to a state you can use. Just get the hex file off the sx chip with SXKey, save the hex file, and run it through angelica.

Good Luck

Thanks so much Kris,
I will give it a go.

The program was written for the basic stamp version of the SX chip.
The eprom has the token codes.
Is there a disassembler for those codes?

bunni

you mean SX/B? no, sorry, AFAIK there is nothing to put the SX/B code back to the way it was.

Bunni,
I think he means he is using the BS2sx chip.

Chris9999 if that is the case, you should re-post your request in the Basic Stamp forum. Make sure to say you are using the BS2sx chip.

Thanks
Yes it is the BX2sx chip. Sorry for the confusion
I will check out the Basic Stamp forum
