My favourite 80's system, the Oric-1/Atmos range of computers, has even gotten a few re-designs as well:
The Oric-1/Atmos machines: https://en.wikipedia.org/wiki/Oric
The SuperOric: http://andre.cheramy.net/super/hardsuper.htm
The AtmoStrat: http://forum.defence-force.org/viewtopic.php?t=1692 -and- http://oric.club/atmostrat
The Twilighte expansion: http://orix.oric.org (^^ named in honour of one of the best programmers for the Oric systems that ever lived...)
One wonders whether or not we won't see, in a few short years time, some sort of return to the retro-computing ethos of simpler computers, more easily maintained by their interested users, for more advanced tasks.
I could imagine, for example, building an Internet capable suite of software for Atmos machines equipped with the Twilighte card, and do away with (for example) using my MacBook Pro for email/casual news reading. The idea of moving to a less powerful architecture for the most common daily tasks, as perverse as it sounds, really appeals to me. There's no reason I couldn't use the same machine as a Twitter client, also...
