Radio Shack PC-2
Whoops. This calculator looks eerily familiar. Of course, I know why. Despite the label that seems to suggest that this is a handheld version of Tandy's venerable TRS-80, in reality this machine is none other but the Sharp PC-1500 handheld computer in disguise.
And a solid, albeit somewhat bulky, BASIC programmable unit it is. Nobody complained that Radio Shack had bad taste when they picked the models that they chose to sell under their OEM brand name.
The PC-2's programming model is illustrated by the following example, computing the logarithm of the Gamma function to high precision:
10:INPUT X 20:Z=ABS X 30:G=2.506628275+6.3E-10+(225.5255846+1.9E-8)/Z-(268.2959738+4.1E-8)/(Z+1) 40:G=G+(80.90308069+3.5E-9)/(Z+2)-(5.007578639+7.1E-10)/(Z+3) 50:G=LN(G+(.011468489+5.435E-10)/(Z+4))+(Z-.5)*LN (Z+4.65)-Z-4.65 60:IF X>0THEN 90 70:RADIAN 80:G=LN (π/X/SIN (π*Z))-G 90:PRINT G,EXP G
