[ih] The UCLA 360/91 on the ARPAnet/Internet

[Jack Haverty]

Curious - obviously my message got through, or at least part of it.
But I got this response:

"
Your mail to 'internet-history' with the subject
   Re: [ih] The UCLA 360/91 on the ARPAnet/Internet
Is being held until the list moderator can review it for approval.
The reason it is being held:
   Message body is too big: 1386210 bytes with a limit of 400 KB
"
I guess the nuances of email protocol still escape me....
