I got a old CNC mill with fanuc control system. The program needs editing and I have a guy with fanuc software that can help me do this. The only problem is that fanuc has made a "EDITING CASETTE" to read out the program from the two chips and into their software. I found one off ebay for $1400 and that's heavy for one time use. I've been looking at this TOP853 programmer. Will it do the job?
The EPROMS are marked "TC57256AD-15" and on this is the list of supported devices on the TOP853. I found a number where the last three digits are zero that fits mine but I can't figure out what the "256AD" is for. The "-15" in the end of the number is for 150ns access time according to the datasheet.
