I have recently got results for number pi calculator runs on the Soviet clone (Elektronika 85) of the Pro-350. The results under RT-11FB 5.01 are: for 100 digits - 0.92s, for 1000 digits - 56.15s, for 3000 digits - 486.28s.
It would be very interesting to compare these results with results from genuine machines (Pro-325, -350, and -380). Screenshots are optional but they are welcome. The number π calculator page is here. This page contains sources for RT-11, RSX-11, 2.11BSD, and AT&T Unix v7. I gather results for EIS-of and noEIS driver versions. Many thanks in advance.

interesting project, how did your soviet clone perform ? does it come close to the J11? I dont have one of those systems but maybe someone here can help you

If I can get these onto an RX50 diskette I will give this a try.

I dare to repeat my request. It would be great to get results from a genuine machine.

The first Soviet personal PDP-11 was the DVK that was released in 1981. They used the original Soviet processor K1801VM1 that doesn't support protected mode, FIS or even EIS. But it was faster than the F11 for integer computations. So the DVK was faster for integer computations than the Pro 325 and 350.
The Elektronika-85 was released in 1985 and it was an almost exact copy of the Pro 350.
The Pro 380 was superior to the all Soviet personal PDP-11. The later DVK used the K1801VM2 (EIS was added), K1801VM3 (protected mode was added), K1801V4 (it is a FIS co-pro). But they were slower than the Pro 380.

K1801V4 (it is a FIS co-pro)

Firstly, 1801VM4, and secondly, not FIS, but FPP coprocessor
