Hubs are still available that are REAL hubs. I got 4 netgears about a year ago and they are still available.
However, there is a problem with your specification: No hub (that I am aware of) can do 1Gbps. All hubs are 10/100 AFAIK.
Ok, so I guess what I am speaking is not strictly a hub, it is a non- learning bridge (single collision domain per port, full duplex, etc). There used to be a bunch of devices sold like this -- there were a few really cheap chipsets (AFAIR, Vitesse SparX VSCsomething was one of them -- basically a standard switch chipset that they shaved a few cents off because there was no learning logic / memory) that many people used in cheap "hubs"... I still have some of these somewhere and will rip the lid off to figure out exactly what it was so I can get some more...
And, note carefully: some "dual-speed hubs" are actually a 10BT hub and a 100BT hub *with a switch between them*. I forget which brand I caught this on, but it bit me a couple of years back.
Which speed cable you plug in determines which hub you're talking to.
I see your weird hub story and raise you one: I went along to one of my wife's clients to help lug a printer up the stairs... We get it on the desk and I go to plug in the Ethernet port -- I follow some cables and find this small white switch jammed behind a photocopier -- I pull it out and it has, emblazoned in large red letters on the front, "10/100 Hub with Switch" -- this was back in the day when switches were still cool... I turn it around, and on the back there is... a switch, one side is marked "10M" and the other is marked "100M"... After I stopped laughing I tested it, and sure enough, its a standard hub, and you can make the ports either run at 10Mbps or 100Mbps by flipping the switch... I *really* wish I had replaced and kept it... W
Yes, it's weird.
