Apparently after just looking at the IEEE standard, and a little (well
actually rather big) book about networking, THINNET (by the IEEE standard)
supports the following...
Cable Media that is supported (Thinnet):
Cable Impedance Description
RG-58/U 50 Ohm Solid Copper Center
RG-58 A/U 50 Ohm Wire Strand Center
RG-58 C/U 50 Ohm Military Version Of RG-58 A/U
RG-59 75 Ohm Cable TV Wire
RG-62 93 Ohm ARCnet Specification
THINNET can also RELIABLY only transmit for 185 meters (about 610 feet).
Maximum of 30 attachments, which takes THINNET or THIKNET out of the
question (This includes any repeaters, or connections on the cable - even
an barrel connection counts as an attachment as far as my book here goes).
I think this is all the info I have at the moment about Thin and Thicknet
Ethernet standards (by IEEE). Hope it helps us all :)
*makes note to go download all IEEE standards*
