Initiating the TDS Pro Survey Program on HP48GX
Im breaking out my HP48GX with the TDS Pro Survey Card and 128K RAM card that purchased and used back in the mid 90s. Problem is I have lost the manuals and cant remember how to initiate the program. I did download a TDS COGO card manual but that didnt work. I do remember hitting alpha alpha twice but cant remember the balance of the key strokes. Can anyone help?
Thanks.
