Hi Amit,

What kind of hardware issues are you having?

One of the problems we had several times was that when the boards were installed or removed from the VME crate the back side of the board could scrape against the VME chassis and damage some of the solder connections or wire jumpers.  Look carefully at the back side of the board for such damage.  We were able to fix them with wire jumpers.

I think there is also a battery that can need replacing that is used for the "non-volatile" memory where the boot parameters are stored.

Subject: MVME-162 CPU Boards

Dear All,

The subject matter of this mail may seem little out of context as far as EPICS is considered. But I believe this community has quite a wide experience and expertise on related matters also.

This is regarding VME based CPU boards from Motorola which were once very popular : MVME-162 ( 68040 processor based)

I would like to know if anyone has experience of hardware troubleshooting and repairing of these boards.

Thanks & Regards,
Amit
