Instructions for use:

you need:
1) a serial null modem cable to connect to PC or similar, to support text transfers
2) the model T laptop with an option rom installed that you wish to extract the binary information from
3) a PC with some form of terminal program, capable of text capture


Steps:

1)  Download the program (rom2s1.do for M100, rom2s2.do for T200) to the laptop.  Use your favorite method for doing this.

2)  Make sure the program loads up properly in basic.  From basic, type load"rom2s1.do".  Should return fine.

3)  Connect laptop to PC with serial cable, and start the terminal program.

4)  Set the terminal program to 19200 baud, 8 bits, no parity, 1 stop bit, XON/XOFF flow control enabled

5)  On the terminal program, start a text capture to a filename like "romdat.hex" or something.

6)  Type "run" from basic on the laptop...so that you are running rom2s1.do or rom2s1.ba.

7)  Once rom2s1 is set up, pressing any key will start the transfer.  It runs to completion.

8)  At the PC, once completed, exit the terminal program.  I've observed that some terminal programs have to be exited for the final captured text to be appended to the file.

9)  Check the size of romdat.hex.  It should be 65536 characters in length.


The data is hex encoded, so 32768 bytes is 65536 hex characters.
