The complete Colossal Cave Adventure in 64K!

[pdragon]

Here's the result of my latest Forth adventure (see what I did there?). This is a full TaliForth port of the original Colossal Cave Adventure (350pt version) for the 65C02 that runs in just 64K. Thanks to SamCoVT for all the support hacking on the amazing TaliForth code base!

I translated into Forth fairly closely from the C code and hadn't written much Forth before so I'm sure there are many possible improvements. Suggestions and pull requests welcome.

That's a really nice setup.

Very interesting, thanks for sharing!

Yay! It is so nice

Impressive all around. That it's running on a breadboard computer is icing on the cake.

I love the diodes there. Make it clear and visible that this is an expensive keyboard with a diode for every key!

If only they were LEDs

I entirely disagree. I see LEDs on a keyboard, and I think it's for some kid gamer who wants flashy-flashy. I see 4148s, and I see that someone's been willing to spend money on real functionality that the gamer kids probably don't even know how to tell if it's there or not.

A diode on every key to prevent phantom keypresses for certain combinations in the matrix is for people who drive stick shift. LEDs are for people who can use only automatic transmissions.

lol, the keyboard is this nullbits kit, love it!

it does in fact *also* have some underglow LEDs which I use to indicate different layers.

it has a more powerful CPU than the breadboard, but i just use it to send ascii keypresses using SPI

We have reached the stage in our hobby of using a five-axis CNC machine to make replacement parts for our steam locomotive...

(and I thoroughly approve).
