For historical amusement...
In reading the Phase II NSP spec, I spotted a summary of how that differs from Phase I. I've never seen any Phase I documents (perhaps no formal documents ever existed?). From the discussion in the Phase II spec, it's clear that Phase I is quite a different protocol. Phase II through IV are all very closely related, especially at layer 4 and above. Not so Phase I -- it would be quite difficult (at best) to make an NSP implementation that could speak both Phase I and Phase II. I don't see any signs that this was ever done. For example, there is no "how to interoperate with the previous version" chapter in the Phase II spec -- unlike the Phase III and IV specs.

How many people on this list have ever used paper tape at a job? My first computer job we used it to control phototypesetting machines. When an 11/70 was added to the mix of gear there, we ordered it with paper tape readers and punches on it to help in transitioning away from the paper tape only gear it was replacing.

Speaking of IBM...what'd be the maximum storage capacity of a punched card? I was thinking of TCP/IP over paper tape last night...
TCP/IP over punched cards carried by pigeons, of course.

I mentioned that in my next reply. ;)

I sense an april 1 RFC here... :-)
Maybe! I could always make it IPoPC/ACR (IP over Punched Card/Avian-Carrier relay)
Classic 80 column punched card: 120 bytes if punched in unrestricted "column binary", 80 byte if punched in extended EBCDIC code (as on the IBM 360 green card) where only one of rows 1-7 is punched per column.
Hmm. It would be rather slow on real hardware, but it seems like it might be doable to "network" older systems. ;)

Hello!
No, what happened is that your place was surrounded by a bigger
version of what Slimer happened to be. It exploded and covered your
place in what is politely called slime.
However there are indicators that it was sent by someone in Ohio.

Yes there are. ;)
73,
Is that a number, a misplaced number, or did I break my encoding again?
It's ham parlance, CW shorthand, that basically means "seeya, have a good one".
Ah. Makes sense. Good to see I didn't break my encodings again...I have a habit of ending up with mismatched encodings...
