You can use 16MB or 64MB SIMMs from an SS20 or Ultra in the SS10.  Sometimes
the SS10 may work with 32MB SIMMS, but I'd like to get a couple more
confirmations on that before I'm really confident in it.

Diag mode will get you much more detailed information than the standard
bootup messages.  To turn it on, 'ok setenv diag-mode? true', unless I've
forgotten since I used it last.
