M8190-AE ; 11/83 CPU
M8190-AB ; 11/83 CPU (or /73??) w/FPU
As far as I know, all the M8190's are _basically_ the same: they are the
KDJ11-B CPU, which support the PMI memory bus, can operate with a KTJ11-B to
provide a UNIBUS, etc. They are the CPU in an 11/83 (with QBUS only
backplane) and the 11/84 (with QBUS/UNIBUS backplane).
The various models of the M8190 vary in details (e.g. although all have a
socket for the FPJ11 floating point accelerator chip, the earlier ones don't
work properly with it), including the clock speed (15/18 MHz, etc).
The 11/73 uses the KDJ11-A M8192, a completely differente card.
