I thought I'd already posted this source, but ISTR that I'd only PM'd somebody about it.

I ordered three of the 5300/EN versions but got 2 and one Video only instead. Both seem to work fine, but one has displayed some interesting characteristics.

Haven't tested the 10bT as yet, but I found my second PCMCIA boot disk and there's a crossover cable sitting on my desk!
