I have done some revision work on the UFOS format. But in my research I found that the format has a bit of variation in it on my old YM6021 the component field has 6 digits and the later YM series it has 8, also does the designator comment crash your machine. The other question was the panel information. I assumed O00001 that is (Oh 4 *zero + 1)was the first panel. If you have any more data / version information,
an old DOS program you know is correct I am very interested!
The VIOS file has also undergone revision and could do with a little more as I have conflicted information on what constitutes a valid line in the feeder part of the file ex: "&F 1=TQFP-44A " my other example has "&F 0=SOL-20000000000000003000000000000" or thereabouts.
