Re: Bull Micral 45 - revival
[please don't repeat the previous message if it's not necessary] Great news. So now we have 3.20, 3.30 and 6.20 variants of BM OEM DOS. I've tested your images, everything seems intact. https://i.ibb.co/VHQLdBN/Screenshot-101.png New v2.2 configuration diskette doesn't take that much long with anim...

Re: Bull Micral 45 - revival
Ok, no problem, if you find some time, check it later.
I've found images of Bull-Micral DOS 3.20 (FR), but these you should already have.
Concerning ST-225, its spindle could stuck after years of non-utilization.
I will think after you'll add more information about its behavior in that topic.

Re: Bull Micral 45 - revival
Quelques nouveautés aujourd'hui. Une page supplémentaire de la documentation qui résume les caractéristiques de la machine : Thank you! This configuration with 12MHz resembles your BM45 machine more. And this photo is better than previous. If he had some time and scanner (or camera and enough light...

Re: Bull Micral 45 - revival
Thank you. It's ok. As far as i see, everything is quite similar. If it's only Z322 what makes that major difference, I don't understand how it's affecting the capacity of my memory slots. I've asked some friends, that's something connected with RAS signal but I don't have proper equipment to deal w...

Re: Bull Micral 45 - revival
That's what I've expected.
Then I can safely pull this pin down to ground without any extra resistance and get turbo working.
Thank you!

Re: Bull Micral 45 - revival
@ Lenord, tell me if you see enough details. The ideal would be that I remove the motherboard but I don't want to do that. Thank you! Photos are great. That's ok, you don't need to remove the motherboard. And when you have time to pull out PSU, take some shots there, most mysterious place is the ar...

Re: Bull Micral 45 - revival
Wow, I'd almost given up hope to get that. Thank you and this guy! It's in French but today I'll learn to read :D But even with the doc I did not understand exactly how SW1-1 and SW1-2 worked. I can explain now. Great that we've got this page, i hope we'll get the others soon. https://i.ibb.co/vvrtP...

Re: Bull Micral 45 - revival
Ok.
Strange that yours don't work with 256K SIMMs. Both 256K and 1M were standard SIMM sizes for 286s.
I've also discovered that it won't work with 4Mb SIMMs, but that was rather obvious.

Re: Bull Micral 45 - revival
I did some tests with different combinations of memories and switches. Thank you very much! That stuff becomes little more determined with your help. I've done the same and created better form of both results: https://i.ibb.co/LJJMv3G/Screenshot-419.png According to what you've got, turning ON #1 g...

Re: Bull Micral 45 - revival
I have found the meaning of the two switch blocks, and some others. See page 239 and on in the book I posted here: http://waltje.varcem.com/book.pdf . That is literally the ONLY info I could find on it... Thank you much, Fred! Best 2.000 page book I've ever read :) Despite some of my research effor...

Re: Bull Micral 45 - revival
[...] I have an answer for "M" - that's because M and V share a key on RU/EN keyboard layout. So that's just a misprint for 45V. Maybe that's an export version, I also think that V letter was original, not a sticker. I couldn't find anything about GenPacific brand. And v1.2r bios version ...

Re: Bull Micral 45 - revival
Yes, but I have difficulty making conclusions. 1- the boot display depends directly on the position of the jumpers but not on the saved configuration 2- the MEM command indicates the same thing as the boot 3- the EMT51 program returns the amount of memory saved by the configuration Same for me. And...

Re: Bull Micral 45 - revival
At first I did not see the count until 6 MB. After a few tries I found that SW2-2 had an influence on the memory like this: Thanks you. So much memory, you're lucky) This is what i get (only if last 2 slots are populated, otherwise all zeros) SW2-1 SW2-2 EMS SIZE OFF OFF 0.5 MB OFF ON 2 MB ON OFF 0...
