Advisory: confusingly, the RS/6000 7043 is one of the few unique 'system types' that features dissimilar hardware! Normally an IBM system type indicates that the motherboard/firmware and other main components remain similar, but not so with the RS/6000 7043 43P and its various (incompatible) models between one another.
To add to the confusion, the Model 240 and 140 look identical externally, but internally they are not. Even more confusingly, the Models 140 and 150 sometimes shared documentation together, but then IBM merged it all with the Model 240 (which is why a lot of PDFs have the Model 140, 150 and 240 together). The Model 150 is quite far removed from the 140 and 240.
Released in 1996, manufacturing ceased in 2000 but IBM continued to support these systems up until 2017 (like most RS/6000s).
Note: Firmware package contains both DOS (.exe) and AIX (.bin) packages
