· Why only 10BaseT ethernet? Why didn't you put 100BaseT on the Mark 2 player?
Because the hardware doesn't include the necessary PCI data bus for 100BaseT circuitry (it's ISA only). Less expensive that way, and the extra bandwidth isn't really needed.
Yes, there is a such thing as ISA-based 100BaseT adapters, but even if one of these chips were in the player, it wouldn't be able to transfer data fast enough to take advantage of the bandwidth. It would still only run at about 10mbps.
Remember that at 10mbps, it only takes a couple of minutes to upload an entire album.
