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.

Code: Select all

2 LET A=USR VAL "3086"
3 PRINT "@80@00@01@02@87@04@05@83@03@85@81@82@07@84@06@86"(RND*15+1);

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)?

Re: Tricks in BASIC

Hi, The dot character equal a "0" integer and don't save memory. (8 bytes) Anyway, it a good code! 8-) I think it is faster then NOT PI and 0, or am I incorrect on that? Also, this line: 7 LET I=I+LEN INKEY$ Any reason why LET I=LEN INKEY$ wouldn't work instead? (i.e., why I had to increment the I ...

Re: ZX81 Clone Tynemouth Minstrel 3

I treated myself to one of these bad boys for Christmas. Wonderful stuff. Although I'm having some difficulties in loading from cassette tape.

The tape player works fine on my Sinclair ZX Spectrum and has also worked perfectly well on my Minstrel ZX80 clone.

Any clues anyone?

Many thanks,

Shaun.
