Excellent site. Pretty new, but read post whenever i have time. This is my first post. I have a 1999 HAAS SL 30. Once in a while while righting a program or editing one, the control locks up with an alarm code K#-965. This automaticly gets added to the end of the program just before the M30. Once this happens it warns you that programs may be corrupted and should be downloaded and deleted from the machine memory. I have no idea what causes this and it is a royal pain. Secondly, i know how to download all programs to a floppy, how can you upload all programs at once. I must be missing something so simple. Any help would be greatly appreciated as I run a home based shop nights and weekends. Thank you.
