Hi , sorry for my poor English  ;)
I have change all the caps on my X68030 but now when i turn it on , i have the boot screen but nothing other

i try with hard disk or with floppy but nothing happens , like it has no rom or can't boot on it
Anyone have ideas about the cause of this?
thx

 Hi Dunmcl !

Try pressing and holding OPT.1 when powering on the system. It will bypass SRAM settings and try to boot from floppy drive. If that does not help, it could be linked to poorly seated components. Reseat everything and make sure that both floppy drives are properly connected with the ribbon cable.

Let us know how it went.

Keep the scene alive !

 Hi !

Did you use the same specification capacitors ? If you are absolutely sure that they are compatible, the problem could be linked to broken traces or corroded traces under solder mask.

Check your X68030 components for the presence of similar solder pads as the circled ones in the following picture. There have been reports that they get corroded over time and fail continuity test.

P.S. While you are at it, check all cables, especially floppy drive, for continuity.

Best of luck and keep us posted !

 Hi !

I remember BlueBMW mentioning that he has the X68030 service manual.
