The
National Semiconductor Datachecker 103 A is just another Account Manager like the Olivetti Chequebook,
the Radio Shack EC-430 or the Texas
Instruments TI-2200
Checkwriter.
Don't miss the Corvus CheckMaster introduced by MOSTEK already in 1975. This rare product retains the balance of your memory even when shut off but uses power-hungry electronics.
