I thought the spec was to default to 10baseT half-duplex if auto-negotiation was not present at either end. That works well enough with a 3c509B in a PC, for example, and it also works just fine with the adapted MACE AAUI in my 840AV and 8100/80, and the 8390-based NuBus card in my IIcx, when I attach those to a 10/100 switch. The 3c509B was one of the first cards to support 10baseT *full* duplex, but did not support auto-negotiation and therefore requires a managed switch (with the port forced to the correct mode) to make use of that feature. However, in half-duplex mode it works just fine as-is. - Jonathan Morton -- -- ----- You received this message because you are a member of the Vintage Macs group.
