This Toshiba SLC-8261 replaced the SLC-8260 introduced few month earlier. It was sold as OEM products, we know the MBO ALPHA 502 and the Radio Shack EC-4007.

SLC-8261_PCB.jpg (120194 Byte)The internal design of the SLC-8261 doesn't look like the usual Toshiba design. We are missing details like the battery holder found in the LC-834WA.
Nevertheless there are other important details inside the SLC-8261. The printed circuit board was manufactured by
Sansyu, a well know company since we dismantled some TI-1750 calculators.

SLC-8261_IC.jpg (151376 Byte)The next surprise could be found on the calculator chip found inside the SLC-8261, it is the same
T3763 found inside the first version of the TI-25.

Don't miss the Canon F-42 and F-55S using a similar calculator chip.

The SLC-8261 was later replaced with the SLC-8262. The SLC-8310 added some statistical functions.
