They're definitely 50 pin, not 64 pin (I just eyeballed one to double
check). AFAIK, only the [23]100 had the wider cables.
A big disadvantage of the 5000/200 is that it only has onboard
ThinLAN co-ax - no AUI connector. Makes life hard in UTP or 10baseFL
environments. Most of our 5000/200's have an extra PMAD ethernet cards
so we can hook them up to UTP hubs.
