Upgrading 3/280S --> 3/480S?

[Stephan Wasserroth]

Hello, out there!

I need some info about two "upgrade" problems:
1. Does SUN offer an upgrade 3/280S ---> 3/480S (that would be a
   CPU-upgrade)?
2. SUN now has 32MB-memory-boards. A 3/480S seem to support both 8MB and
   32MB boards (up to a total of 128MB). Is it possible to put the 32MB
   boards into a 3/280S? If not, why doesn't it work? Is it possible
   to put more than 32MB into a 3/280S?

The "official" answer (our friendly sales rep...) is:
1. CPU-upgrades only 3/280S ---> 4/200 (but we need 3/... no SPARC!)
2. No 32MB boards into a 3/280S. Reason unknown.

Both answer make me wonder! Are there technical reasons? Or should we
throw flames against marketing? Any comments? May be from SUN?

P.S.: Two "features" about SUN marketing:
      The basic network-workstation are configured with "standard 4MB
      memory" - even the 3/80. But SunOS 4.x machines should have at
      least 8MB (so says SUN)!
      At least in Germany the 3/50 aren't gone. You may order them. You
      ask for the price? More than 80% of the list price for a 3/80!
      FLAME: SUN MARKETING!! THIS IS RIDICOLOUS!! GET SERIOUS!! flame off.
