I totally agree and this threw me for a bit of a loop when I was testing
my 11/24. I can do a quick check next week, but from what I can remember
I was baffled at no ODT until memory was in. Maybe it was the 7273's but
I went through 4 cpu boards trying it. Memory in and it all worked.
And I have 3 spare 11/24 cpus all in working order for sale if anyone
needs one :-)
I'll double check later.
