I work for the Department of defense and we have an HP 9825A calculator used in a very old application. We are trying to make a copy of the program tape that is used to prevent loosing the program until newer technology is intoduced over the next several years. We have not been able to have the tape duplicated. Can anyone offer any suggestions.

Can't you simply load the program(s) into the 9825 and save them back out to a new tape?

Programs are OK, but what about data files? You have to read them in, and then save them without messing them up.

BTW have you looked at the 9825 manual? This thing is totally wierd.

Apparently there are some files that are protected some way. It will not allow us to copy all the files. Some copy fine others do not. To the best of my understanding there is some type of duplicator tape that allows you to copy the other tapes and the one that we have is bad.

Can it be true that the DOD is still using 1980's technology to run an important application? I admire the DOD's frugality in not updating hardware and the quality of HP's older calculators. However, if you think better technology from HP is right around the corner you might be waiting a long time.

You start of by questioning the use of old technology and then turn around and say...

"However, if you think better technology from HP is right around the corner you might be waiting a long time."

Which seems to imply that no new technology is better. So which is it? You seem to be giving an argument for using old HP while at the same time, questioning that.
