Thank you for our responses.
First I enclose my question :

> Hello,
>
> We plan to upgrade our two old SS1 in "simili-SS5".
> We plan to buy two Cycle 5 Upgrade Boards from Cycle Computer Corp.
> It seems worth the price since it allows the swapping of the SS1 mother
> board by the new one, and permits to use all the old devices (memory,
> video-card, screen, etc.)
>
> Is somebody have ever used one of this Upgrade Board ?
> May you share your experience with me ?
>
> Thanks a lot.
> I will send a summary.

I have received 6 answers.

This motherboard seems to work fine and speedy. But not as speedy as a =
true SS5 since the SS1 memory is not as speed as the SS5 memory.

Some advices are :
- If we mix different kind of memory (SS1 style and SS5 style), we have =
to switch the motherboard to the lowest memory speed (100ns).
- The old disks are just SCSI, not FAST SCSI-II.
- Check the price on the shops around.
- Try a SS5 clone without a screen and use the one's from the SS1.
- Look at the Axilerate board from Axil Workstations.

So in the meantime Sun has announced the SparcStation 4. So, before =
buying anything, we will wait until we receive more informations on this =
new one.

Thanks a lot to you :
