So I put a test clip on the option rom and wired it to a 27C256 pinout but my TL866 and couldn't read the rom. Can anyone verify that the pinout here ftp://ftp.whtech.com/club100/rom/pinouts.txt is correct?
I found ARTROM (also on club100) which does indeed dump the option rom to the serial port to a rom burner called an A.R.T which I saw a picture of on club100. I thought I might be able to capture the serial port contents but I'm not seeing any output from the T102, so there must be some handshaking expected. I was hoping this had an easy answer to it. I guess I'll doubleXtriple check my wiring and try the TL866 again.
