I saw online where someone had a text version copy of their ladder. Any suggestions on how to achieve?

I have an Oi-Mate-MB and backed up SRAM on my machine on a card and got two files with names SRAM1_0A.FDB and SRAM1_0B.FDB. Is there a way to view the ladder from these files without buying special expensive software?

Also, I tried to get the ladder to punch to my PC via RS-232 and just kept getting errors. Despite the fact that I dripfeed from the PC all the time and can send and receive programs just fine plus have been able to punch the other data (parameters, pitch comps, macro variables, tool comps, etc). For some reason I can't get the ladder. Am trying to follow the steps exactly in the Fanuc Maintenance Manual (Section 3.2.3) with no luck. For examples, in step 11 is the "floppy cassette" what you select for RS-232 output, and in step 14 where is the "@" symbol on the Fanuc keypad or am I missing something obvious here?

Man, I love Fanuc for its history and commonality but they sure don't make it easy on a guy

Thanks fellow Fanuc sufferers
