The system ROM of the Model 100 laptop has one error within its logarithm
table. Rather than some early model 100s being afflicted, my
understanding is that the erroneous logarithm table is present in the system
ROM of all Model 100
The system ROM of the Model 100 laptop has zero known errors within its
*logarithm* table (as Ron wrote)--there is one known error in a
*trigonometric* table.
ATN(1) is also miscomputed for NEC PC-8201 BASIC Ver 1.0 and OLIVETTI M10
BASIC 1.0, in addition to the TRS-80 Model 100.
