Is the PLC working now and where you can get access to it? I do have the software, a cable and a spare PC 085 to pull the program off an EPROM. If you have the PC085 available, and you can pull the EPROMS, and there are (2) of them, and can burn a copy of them, and then send them to me, I can pull the ladder off them here. If there is only 1 EPROM, this method won't work. The program is then only in battery backed RAM. If you are going to use the tape, you would need the PP 0105 to interface with the cassette player. The cable and software is the only way I know of to get the ladder into the computer, other than burning some EPROMs as I mentioned above. Of course if you wanted to send the PLC I would be glad to pull the program off it for you for free, then return the plc for shipping fees only. Perhaps if you have an old cassette player you could make a .wav file to use it on the computer as an additional backup. Unless the only accessable copy of the program is on the cassette tape, I would recommend staying away from that option. By the way, I have a PDF of the manual around here somewhere if that will help.
