Weitek and were
Their main differences were the CPU, RAM, and Weitek Floating Point Accelerator boards, disk controllers and disk drives ( both ST-506 and SMD were available ).
Some floating-point units, such as the AMD 9511, Intel I8231 and Weitek FPUs were treated as peripheral devices, while others such as the Intel 8087, Motorola 68881 and National 32081 were more closely integrated with the CPU.
