Nice! I have one of those in my personal stash, haven't done anything with it, but I may dig it out soon. Such a cute little board.
I am unfamiliar with this SPEED3 benchmark that you've run here. Where can I find that?

This is a (heavily) modified version of the program that came with some (personal) computers compatible with PDP-11, made in the USSR.

You can download from here: http://www.kpxx.ru/soft/utils/Speed3

SPEED - original version
SPEED0 - a shortened version for a quick assessment of the processor speed on two commands
SPEED3 - version that disables the cache (if any) and evaluates the speed without cache memory
SPEED4 - version that enables the cache (if any) and evaluates the speed of work taking into account the cache memory

But, I apologize, program messages are in Russian, comments are in English to the best of my knowledge of this language

mcguire · Feb 27, 2022

That's very useful. Thanks! I will be running this on some real hardware at LSSM.
Do not worry about the language differences, I will figure it out.
With all the craziness going on in the world today, I'm glad that I was actually able to reach your website.

Exotic - J11 (KDJ11-B) at 24 MHz with cache hits:

Type a command then press the RETURN key: MAP

I have plans to make a version with messages in English, but there is no definite time in the plans...

mcguire · Feb 27, 2022

24MHz!! I've never seen a J11 run that fast, I bet that's nice!

-Dave

Hunta · Feb 28, 2022

As the tests of the J-11s I have showed, the chance to get the J-11 at a frequency of 24 MHz is 60-70 percent (for the -09 J11 variant). But I have only two KDJ11-B boards and I replaced the quartz on only one of them, so there are no statistics on the performance of chipset microchips at an increased frequency.

mcguire · Mar 1, 2022

How is the temperature of the J11 when running at those frequencies?

-Dave

Hunta · Mar 1, 2022

I can’t say for sure - two fans blow over the boards, but after turning off the stand and removing the board, the processor is barely warm

The bootloader for HX has been added to the standard ROM. Work is underway to optimize the code to save regular loaders for DD, DX and DY.
