Reading 9845 tapes in HP-85 Message #1 Posted by Chuck Guzis on 7 Apr 2005, 9:06 p.m. I've been asked to read a bunch of DC100A tapes created on an HP9845. While I don't have access to a 9845, I know where I can borrow an HP-85. Can the 85 read these tapes or am I expecting too much? Thanks, Chuck

Re: Reading 9845 tapes in HP-85 Message #2 Posted by Vassilis Prevelakis on 7 Apr 2005, 10:50 p.m., in response to message #1 by Chuck Guzis If you are asking whether you can insert a tape, type CAT and get a listing, the answer is, unfortunately, no. If you are willing to write a program to read the tapes, I think it can be done, but it'll have to be in assembly as BASIC does not allow low-level access to the tape drive. You may have more luck interfacing the HP-85 with an external (HP-IB) tape drive that is compatible with the HP-9845 tapes. BTW anybody knows whether the 9845 tapes were read/writable by the 9825? **vp
