well, the thread is not as old as not to mention something very relevant:
"The original ROM image
(.bin files copied with the programmer
) is not publicly available for commercial reasons. I know an unfortunate 300HC user, who has been Begging for the ROM image on forums but to no avail, even though he has the right EPROM programmer and the know-how. Another luckier user had to send his 300HC almost across China to have his 300HC suffering ROM loss fixed."
well, i don't know what commercial reasons are there, but if someone is in dire need of such a rom and is willing to overlook those commercial reasons, i probably have a valid rom dump of the celux.
btw really strange story as to how i did the rom copying...

at the moment the screen isn't working
(waiting for repair
) so i did everything only using keypresses on a japanese hpc2000 system
(if it was english, it would've taken only 1 minute to do the dump
) and had to use infrared for getting the rom files off the machine
(whew, sending 32MB over infrared
).
