SWF operation box OS upgrade

SWF/B-UK1204-45
floppy

Thank you very much indeed!
Probably it is what I need, I run it on my PC, parameters seems to be, that I'm looking for. But when I try to install this file on my machine, it says "program too big to fit in memory"...
I don't know reason. Maybe because I have only 4mb memory installed. I will try to set one more 72pin old memory card. Maybe it will help me.

forget to attach picture

Yes, before upgrade I pressed f1+f2+f3, then I chose F1 - Flash Format, internal memory was clear. And then, after reboot, I pressed f1+f2+f7 and chose F1 (system install).

Wow! But how can I upgrade this?

Thank you!
Please, look at the pictures, this is my system.

As I see - it's v.1.8

By the way, frolito, Do you have old system files? In case if something happens during update, I could have possibility to recover system.

I did backup system file. The name of this file is SWF_C.exe
But when I try to install SWF_CB.exe (that you give me) - it says "system file not found"
When I try to rename SWF_CB to SWF_C - it says "program is to big to fir in memory"
What about another file, that you give me - SWF_BB.exe - what is it?

Thank you, Frolito, I appreciate your attention to this question.
Upgrade costs too much... So, maybe later I will buy brand new OPbox.

I would never want to upgrade system, but I have problem - looping during embroidery. Problem is in frame start moving angle. In old OS there is no possibility to change these parameters. But in new OS we have new part of parameters.

I've spent some time with testing and learning.
I have 6 different version of OS files. But in every file there is no possibility to choose trimming method. I need to chose "motor", but in new OS there is only "solenoid"...
So I need older OS file...
