Re: Vintage Speech+ Telesensory calculator

From: Katie Wasserman


I have one and had to replace the rechargeable batteries in mine too (of course). IIRC it uses 4 AA nicad cells which aren't too hard to replace. Opening the calculator is easy enough, just 4 screws; but closing it up is a little tricky because it uses some plastic spacers to keep the circuit boards in place and the screws need to go through these spacers. It's definitely worth the effort, it was really innovative and expensive way back when and sounds pretty cool!
