The
Datamath
Calculator
Museum received this
PLT USB1 Universal Serial Bus Module together with some unique graphing

document it.
The Dallas,
TX
based team nicknamed it PET Project including three advanced graphing
calculators:
•
PLT
SHH1: Spot Hand Held,
first generation PET device with smaller, portrait oriented screen. • |
This PLT USB1
Universal Serial Bus Module was developed for the PLT FHH1 and PLT SHH1 to connect with
external devices using the USB 1.1 standard. The related PLT SHH1 offeres with
the PLT DS1 Data Sled a second option to supports USB 1.1 connectivity.
Disassembling
