テレビは２台と、ビデオキャプチャボードがついたPCが１台ありました。
回線も、PSOは回線の帯域をそんなに使わなかったみたいで３人プレイに関しては問題なかったです。

当時はフレッツISDNで、もうつなぎ放題になってたような気がします。

I had two TVs and one PC with a video capture board. As for the lines, it seems PSO didn't use that much bandwidth, so it was no problem to have three people playing.

I had FLET'S ISDN at the time, and I get the feeling it's now become so you can connect all you want.
