[Oberon] oberonstation questions, ps/2?

[Lars]

Was wondering why PS/2 was chosen for the oberon keyboard and mouse ports
when all the keyboards being sold in stores these days are USB. Was ps/2
much simpler to program without complexities of USB ?  Drivers easier to
write?

Do people use USB keyboards with a ps/2 converter? If so, do almost all
USB keyboards have the ability to use ps/2 with a converter, or are some
USB keyboards USB only, no conversion possible.

Also, no HDMI video, DVI? too complex? the svga port is a little bit
outdated. Any plans to release an OberonStation version 2.0 or something?

Note: I am completely ignorant of the OberonStation. If these questions
have already been answered in a book, or on a website (non existant "Wirth
Blog" or "Wirth Wiki" or "Spinach Planet") then let me know where to read
info.
