Re: Token Ring

[DrFranken <midrange@xxxxxxxxxxxx>]

The 2744 was THE PINNACLE of Token-Ring development as it ran at a 
staggering 100 (yes two zeros) Mbps! I installed exactly one of them for 
a customer who was using Token Ring. Soon as we upgraded to that machine 
but before we connected it they dropped T/R for Ethernet. :-)

It also supported 16M (and maybe 4M too, I don't recall.)

I'm quite sure that card would work on a POWER6 with PCI-X slots as it 
took an IOP to drive it.

For all I know it's still works in i 7.2 too as the CRTLINTRN command is 
still in i 7.2!  AND -trivia of the day- POWERHA supports replicating of 
Token-Ring lines!
