DIMMs don't weight much, so you woulnd't have to get them locally.
If you can find a good deal on them from a US vendor that will ship
international, it might be cheaper than locally.

You won't.  Sun Microelectronics did not publicly publish information
on that board.... only with later boards did they start to make information
widely available.

I have a manual for an Aries Marixx SS which uses that board, so I have
the jumper information (although I seem to recall there is an inconsistency
in the manual on 40/50MHZ MBUS speed jumpering... quite aggravating).

Well, supposadely the module-info command will report the mbus speed,
but either mine is not doing 50mhz or the module-info command in my
OBP version is not reporting accurate information.

In solaris I belive you can get this information (although you have to
hunt for it) in prtconf output I believe (I don't recall the options but
I think you need -v).

>BTW: What is the main difference from SS10 to SS20? Only MBUS and RAM

Mbus, RAM speed, SX video is there by default (i.e. no SS20SX) just add
the VSIMM, sca scsi (although still narrow) vs 50 pin scsi, built in
cdrom drive (with the later Aurora II Sun chassis they switched to a
full height drive rather than that third height design), and the addition
of standard audio jacks on the back rather than needing an external speaker

Shipment would not be expensive.... depends on the shipping option and
wether or not you want it insured.  Payment may be trickier, but I've
had good luck with international bidders using bidpay.com.  bidpay.com
sends me a US funds money order which you purchase with a credit card.
There is also paypal if you have a paypal account.

I just checked and I can ship one new in the box to Germany for $8.70.
(delivery time estimated at 4-7 days).

For insured shipment, $15.85 becomes the cost (because only Airmail
Parcel Post and Global Express can be insured, Airmail Letter Post and
Global Priority can not be insured).

If your interested in one of these, e-mail me off list, I will ship to
