Hello All,
We have an Apollo 3000 which is a 68020 box based on an AT bus [just
like a PC]. Our machine has a token ring board which is of no use to
us. Apollo offers another board that supports tcp/ip. My boss being
notably tight-fisted balks at spending $700 for a board. On the other I
suspect that the Apollo board is merely a 3COM503 Ethernet II. It would
be nice to verify that.
Does anyone know?
Thanks alot...

[...] The only problems are: 1) there is a special chip that Apollo adds to the 3COM503 board that lets it figure out its unique 48-bit Ethernet hardware address (based on the Apollo's node id), and, 2) the original Apollo DN3000's didn't understand anything but token ring boards, and there is a boot PROM (or something) on the motherboard that needs to be replaced for them to accept an Ethernet board as its primary network.

Actually, this little PROM isn't necessary at all. The only thing it is used for (apparently) is self-diagnostics at reset time. If you take out your ring card (like I did from my DN3000), the diagnostics will fail because the Domain PROM tells it to look for a ring card. But since this check comes last, the loss is trivial. You can EX AEGIS anyway. According to our service rep., replacement of this PROM is included as part of regular maintenance. I haven't bothered. ...lori

When you order a workstation you have the choice of PHYSICAL interface i.e. either Token Ring or Ethernet 2. The TCP/IP protocol is generally independant of PHYSICAL interface and can run over both token ring and ethernet. It appears that what you really _want_ is to run on an ethernet physical interface with TCP/IP as your transport (and other) protocols... -- Danny Wilson IDACOM Electronics danny@idacom.uucp Edmonton, Alberta alberta!idacom!danny C A N A D A X.400 danny@idacom.cs.ubc.cdn

The PROM (?) is necessary for *diskless* machines (yes, we have a few) to be able to boot over the ethernet. We have a node without this PROM still running SR9.7 because we can't get it the recognize the DI E command to run the SR10 invol. Yan. )~ Yan K.
