Anybody remember Ladder from the CP/M days?· My dad let me play it on his Kaypro when I was a kid...

It's something like "Donkey Kong" but with text graphics...

Update:· Added a 640x480 version, removed test code

Note:··"ladder_vga" requires a vga monitor capable of 640x480·and a keyboard
········· "ladder1a" requires·vga monitor capable of 1280x1024 and a keyboard.

I think it's all done now.
But, I don't know for sure because I haven't made it to the end yet...
One note:· Don't hold keyboard keys down, just hit a key once for an action...

Here's a preview pic and final codes (ladder1a.zip, ladder_vga):

    holly Smile!!!! I spent hours playing that game! I'd love to play it again for fun. My dad also purchased A kaypro, our first computer for around $1800.00, I think after many many hours of playing I beat the game only to find out the it just starts out again only faster. monochrome, text for graphics games those were the days!!

    Nice work!

    Excellent. I was just contemplating spending the time to understand how to get the original code for this working under CP/M running on my 8085 emulator for the Prop. So I'll be looking into your code[noparse]:)[/noparse] If something like the ladder game would work I'm sure we could have Wordstar etc running on the Prop as well.

    heater, I'm actually starting from unix curses c code, not the original CP/m source..

    Ah, THAT curses, of course. I guess the original CP/M ladder used escape sequences for VT100 terminals or such which I have yet to look into.

    Got it working! (I think). I've updated the original post with the latest file...

    It's still pretty fun (and challenging) after all these years...

    That game makes me remember the old TK-85 (discrete version of a CZ1500, ZX-81) Donkey kong. It was also text with low resolution "graphics" at 64x48. The game was pretty cool for my age and that machine smile.gif. The floor had some arrows that dragged the player in a direction and made your life more difficult. The fireballs were asterisks and they even followed you!. what memories !!

    I think it's complete now... I posted a new version to the first post (ladder1a.zip).

    Just did a quick hack of the VGA_HIRES_TEXT driver to get it to do 80 columns x 30 rows in 640x480 mode. This works pretty good for Ladder...
    I added this version to the original post and removed a test versior
