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??
