TI-2500 Calculator




Comments:
  • Identical to my very first calculator (that I bought back in the early 70's ... probably 1974 or '73)
  • Received last week (a retro Christmas gift)
  • I didn't think it worked but I didn't know how to turn it on. Today under close inspection I found the on-off switch
  • Model is TI-2500B
  • I'm surprised this still works ... but it works like a champ
  • I love the clunkiness
  • See earlier post

TI-2500 Calculator


Comments: I'm am bidding on a TI-2500 Calculator on EBay. I bought one of these new way back in 1974. Checkout the Datamath Museum for more information on the TI-2500.
