I saw the board was sold :-(
Eeek, sorry, that was me...
But, thinking about purchase one if the occassion is
present...
How exactly could be done the connection ? We have the M8189
and the M8188. Where or how is connected one board with the
other ?
The FPF11 has jumpers along the bottom which determine which backplane
pins it uses for power and ground. These allow it to be plugged into
either a Qbus or a Unibus backplane, for use with a pdp11/23 or a
pdp11/24. As far as I recall, it uses no signals from the
backplane...only power and ground. It connects to the processor via a
40-pin flat ribbon cable which terminates in a 40-pin DIP header.
This header plus into one of the MICROM sockets, where one would
normally plug in the floating point microcode ROM chip. It should
work with any F11-based system.
