Having failed completely – by its own lights – with PCjr, a personal computer designed specifically for the mass retail market, IBM is considering trying again in the US, but this time with the low-end models of the PS/2, the 25 and the 30. It has been test-marketing them through four Burdines department stores in South Florida since September, and will decide on the basis of the test whether to go ahead US-wide. The move risks alienating IBM’s dealers, especially if the mass retailers start heavy discounting. IBM says it is a good time for the test because the Model 25 is a Christmas kind of a machine.
