Overview

Found on the model 50 and 60. The model 60 includes an additional chip (72X8287ESD). It supports 10MHz operation. It is very similar to the Model 80 T1-T2 chipset. There the 72X7385 (Bus controller) has been replaced with discrete logic and 2x 8259A-2 (Programmable Interrupt Controllers). Speculation: the 72X7385 contains two 8259A-2s.
