Re: Dropout 1K BASIC listing

Thanks for the text listing XavSnap :-)

Out of interest, how do I use "Xur" text files?

Regards,

Shaun

Dropout 1K BASIC listing

Here's Dropout to type in:
Dropout 1K
Dropout 1K
Use 1 to move left and 4 to move right.

Happy typing!

Edit: I've added a slightly improved edition of the game for the unexpanded ZX81 which doesn't "flicker" the catcher when you play.

In what way? DEF FN can be used for any calculations, so yes. You may also be able to use the USR command with it as well to call let's say certain ROM or MC routines directly.

Re: ZX81 Clone Tynemouth Minstrel 3

Just a thought, does the Chroma Interface work with the Minstrel 3 clone? If so, is the Chroma still available to purchase?

Thanks,

Shaun.

Greet Master…
16K of RAM ought to be enough for anyone, right?

Excellent work, as always!

One day the apprentice will become a master.

I've added additional white spaces for some more readability. Remove them to save bytes.

Re: is there an updated zx81 rom?

Is there a Forth ROM (or other language) that will work on the ZX81 Minstrel Clone by any chance (or real ZX81)?

Regards,

Shaun.
