Continuous Memory TM? Message #1 Posted by Tom (UK) on 9 May 2001, 7:10 a.m. Who had 'continuous memory' first? I have seen a TI-44 (BAII) calc manual (from about 1984) where it says: 'continuous memory TM' HP had the 25C (in 1976) which had 'continuous memory' printed on the case. Was this an infringement of TI's trade mark or did HP forget to trade mark this name and TI 'stole' the phrase??

TI used "Constant Memory" Message #2 Posted by Gene on 9 May 2001, 5:21 p.m., in response to message #1 by Tom (UK) AFAIK, HP was first with the HP25C. TI used the term Constant Memory on their models, including those that just saved the contents of one memory! (Like the LCD TI-50). The biggest one they made in terms of utility was the TI-58C (the first calculator I ever bought with my own $$). It kept 480 program steps or 60 memories when turned off. TI never made a constant memory TI-59, which contributed to their marketing problems in the early 1980s. Hard to believe but TI essentially gave up the calculator market to HP and casio, etc., at the time. My, my how things have changed! Gene
