Now I have it in my hands

The machine itself is in excellent condition with the case never being opened.
This does of course mean that the PSU has never been recapped and is most likely going to fail at some point in time.

As it's such a nice example I think i'm going to treat it and see what we can do to upgrade it.

Next steps:

• Recap the PSU
• Investigate options for modern TV, VGA, Possibly even HDMI output
• Options around floppy disk drives and modern alternatives.
• Rom Upgrades
• Giving it a makeover

As I get to each stage I'll create a sperate blog post to document my journey.
