Apologies for any ambiguity, but to be clear, the genuine StarLAN
transceivers I have are working fine on my 10BaseT network at 10Mbps,
not 1Mbps.  I was not trying to suggest you could plug a true 1Base5
StarLAN network directly into a 10BaseT network.

Is it possible that different kinds of devices were all badged "StarLAN"?
