[mod.computers.vax] Ethernet LANs

Two questions...hopefully lots of answers:

     I am in desperate need of Ethernet hardware... preferably thin
Ethernet, and I need it delivered within the next two weeks (!).  The
problem:  I cannot find any dealers/manufacturers that sell the stuff
and can delver it soon enough.  Does anybody know of a reliable and 
stocked source for three transceivers, cables and associated accessories?
(We are located in south-eastern Ontario, near Toronto)


     While on the Ethernet topic.... can anybody elaborate on the 
Ethernet topics...
                          thin ethernet/thick ethernet
                          IEEE 802.3 / ?
                        * Ethernet V1.0 / Ethernet V2.0  transceivers
                          Transceivers with a "Heartbeat"            
                          
We are experiencing some problems in communicating between Sun workstations
and uVAX's and a VAX 780.  In one case, a remote login prompt takes about
20-30 seconds to get... as if communciations were in almost continuous 
collision.   I have heard rumour about "slight incompatibility in timing
and signal level thresholds" and "differnet revisions of the IEEE 802.3
standards".    Comments anyone?
