VERY interesting phone call re: HP 9845. Can you help?

I just got a VERY interesting phone call from the US Department Of Defense Cybercrimes division. I don't think it would be prudent to disclose the details but this MAY turn out to be VERY important. They have several HP 9845 tapes that they need to read. Can anyone help? Yes I know all the problems about the HP tapes and tape drives. I'm the one that found most of them so let's not rehash that. What I'm looking for is a working HP 9845 with a working tape drive preferably in the Washington DC area. Also information about linking a 9845 to a PC or other modernish computer so that any readable data can be transferred to a modern format. I know there's been some discussion about trying to read HP tapes on other devices. Has anyone tried to do that yet? I have several 9845s but I haven't fired up any of them in a couple of years and I know none of them have a working tape drive. I have rebuilt the drives on other HP but never bothered to in the 9845s. Joe
