Full set of chip :)

Nice!

You might want to hunt for an FPF11 (M8188) next - it is the super-fast floating point accelerator for the F11 chipset, using a boardful of AMD 29xx bit-slice processors. It plugs into the FP11F socket on your M8189 CPU board and pretends to be a FP11F (but a really fast one!).

Nice, now I want to see the rest of the system too ;)

Maybe nice to tell a bit about yourself also? Where are you from?
Do you collect more pdp stuff?

I will take a picture, but this is not a completed PDP-11, but rather a stand for experiments. And it look awful :)

I am from Russia, on the PDP-11/03 Soviet counterpart computer I studied programming and computers - these were the days when computers were big and programs were small.

I have a collection of processor boards - from LSI-11 to KDJ11-B. To boot operating systems I can use RQDX3 and CQD-420, to which I can connect hard drives, and to CQD through an adapter - CF cards. And I have a homemade controller (not by me) to which you can connect up to 4 CF cards and one SD card. CF cards are visible directly (I wrote drivers for RT and RSX-11M-Plus), and the SD card emulates old controllers, currently RK11, there is also a firmware for emulating RLV211.

The KDJ11-B has a firmware to boot from CF cards directly. The others processor boards I can boot from CQD-420 or thru serial line disk emulator, created by one russian friend.
