There are loads of such projects out there, even a commercial one called 
C-One "the reconfigurable computer", here:

<grin>  What do you use for papertapes?  We used to make a "tray"
[don't remember what we called them] of papertapes which would get
shipped with the PDP-8s.  They may have been diags, or bootstrap,
or something...I can't remember what was written on the labels
right now.

It is a great effort but last time I checked it was a bit pricey ~$300
for a basic system.

Just my opinion but some of the other ways of doing it will be more
successful if volume is the sole criteria. For instance all those
MP3/4 type players seem to use some variation of Rockchip or Sunplus
'System on a Chip.' In the Sunplus case it has ~160 mHz ARM processor
as the core. Currently they only emulate NES or GB, type of old system
but they certainly have the processing power and enough I/O sans
keyboard to do most 8 bit and 16 bit computers. Build quality is a
problem of course but you can pick a 4 gig system with LCD screen for
about $50.

Another terrible moment in a deeply terrible movie.

I wanted the dinosaurs to kill them all. And quickly.

But the neat thing about the C-One is that it has support for what, 10 
systems in total and at the least 4 of them really good.

There is also some support for connecting to older hardware and more on 
the way I gather, but frankly it is more of a hobbyist unit than what 
you are describing

Just out of curiosity, how old are you?  Giving the decade is OK.
A game system is that price so I'm wondering if "kids" think $300
is too much.
