I have done these and they have displayed the ROM in the machine, but they did not display the ones I was looking for. I have my BBC connected to a CNC lathe and until about 6 months ago it worked from a 5 1/4" floppy, This no longer works and now displays the message "Disk Fault 08" and as a result the lathe no longer works. I found two ROM chips inside the system which have written on them "Techsoft CNC Designer" but they cannot be found by the computer. So I need to find the original software and copy it over onto more of a reliable type of memory. The software is made by Lander Microsystems (for the Conect 121 CNC Lathe) does anyone know where I could get hold of this in any format compatible with the BBC? Thank you.
