1985. A late model in the TPA-8 line, one with bitslice processors, LSI components, and a new system bus called the AMBUS. However, it was still software compatible with the earlier 12-bit TPAs (and of course with the original PDP-8), and with the appropriate adapter, all the peripherals used on other TPA-8s could be accessed.
