Re: New Tapes Available for the 85, 9815, 9825 Message #3 Posted by Katie on 23 Sept 2004, 11:21 p.m., in response to message #2 by John
While I don't have first-hand experience using the DC1000 tapes in the 85, I do have a lot of experience using them in the 9815 and 9825. My experience is that they have never had any failures at all. I've used dozens of these tapes over the years and they've all been good. I haven't even had so much as a one-time mis-verify.
I agree that the coercivity rating on the DC1000 tapes is higher than the DC100A tapes, but my guess is that the 9815 and 9825 (at least) use a lot more current than was necessary to write the DC100A tapes with.
Aside from my direct experience with these tapes, I've sold many to other calculator users and have had only good reports on their use in all three machines.
