Product Alert #25
STARLOGGER - Model 6004B - Ser #s to 2348 - V22.4
Incorrect result - DDIVS (signed divide) Instruction
22 August 1995
Problem
The signed double divide instruction returns incorrect results when a negative numerator is divided by a demomenator greater than +/-255.
Symptom
The MSB byte of the denominator in a DDIVS instruction with a negative numerator is incorrectly read as zero.
The DDIVS instruction is not used in standard scheme generation, so this error may not be noticed.
Correction
Upgrade firmware to Version 22.5.
