Whilst I'm on the list....
I hope no-one is offended by the idea of using the Model 200 shell and
keyboard as a housing for more modern components. I thought about this
for the Model 100/102 but the aspect ratio of the screen does not lend
itself to finding a modern equivalent.
I have found a 7" TFT screen that will fit within the existing bezel of
the Model 200 and would be looking to install a raspberry pi with an
arduino providing the conversion between keyboard and USB.
Has anyone tried this before? I haven't come across anything on the net
(so far). Would be interested in people's thoughts.
BTW - this came up on the Retrocomputing Rountable Podcast in a recent
episode (http://rcrpodcast.com/)

Thought if you hadn't seen it might be of interest.
Regards, Mark.
