Re: Programs on tape

Yes, that is what I've been doing gammaray. "Periodic analysis"--looking at the size of the bits in the dropout, and then overlaying a "healthy" 4 or 9 bit pulse to replace them. Sometimes I can't really tell how the area should have looked, and then it becomes an "educated guess" at where the valle...

Re: Programs on tape

Partial success,... I went after the .wav images with a sound editor, and "cleaned up" Programs 1, 2, and 4 to a point where they will load reliably to my Lambda. Muppet Labs.jpg Program 3 however, has severe dropouts, and I have been unable thus far to repair the missing areas with cut & paste embr...

Re: Programs on tape

Hi Jørgen, and all, I too am looking forward to working with those .wav files, hoping my "Scrubber-Dubber" gizmo can retrieve questionable images and write cleaner copies. Like you mrtinb, I have zero "native" software for my "Your Computer" (what an insipid name) version of the Lambda. This is very...

Re: A Gaggle of ZX81's for sale

No power or accessories--tough sell. Somebody had aspirations of distributed-computing something or other, but with today's Arduino and Fruit Pi platforms, there are better ways. It would be nice to refurbish them all and sell them one-by-one, but collectors want the full package. Being on the Ameri...

Re: 2k adventure

I won't be expanding it. As a 2K Adventure game it was a development novelty only--a fun exercise in coding. A full-RAM version with more rooms and features would require a redesign of some of the compromises to make to fit into 2K, and Adventure games abound in the wilds. (I think the one I posted ...

Re: 2k adventure

Thank-you Siggi. That helped a lot! Success. It took some more crash dieting, but it now fits in an un-expanded Timex-Sinclair 1000 with the core game intact. 10 SAVE "ADV2k" 60 PRINT "YOU ARE IN ";R$(R),"THERE IS ";O$(R),,,"YOU CAN GO:",,(N$ AND R<V3),,(S$ AND R<V4),,(E$ AND R=V4),,(W$ AND R=V2) 10...

Re: 2k adventure

I started my program on a "Sinclair Diet", but I don't think I'm going to make the 2K finish line without some major loss of functionality, which I'm reluctant to do. :cry: So. I have failed The Challenge. "This school is about combat gentlemen. There are no points for second place." :lol: 3KADV.p H...

Re: 2k adventure

I took a different approach. I'm a firm believer that programs should be bullet-proof and robust. But Adventure games are a challenge, especially when limiting oneself to 2K! So I tried for 4 rooms and 4 feature items. In the end it's more like 3K. Anyone care to pare it down with more of that PI/PI...

Re: 2k adventure

I also read the machine code articles for the zx81 and need the basic equivalent of LDIR, ADD and RET, if you could help with that, I'd be grateful Hmm. Not sure where you're going with this, and I'm not terribly Z80 assembler literate, but I'll take a poke at it. (Whoops,... THAT was a poor choice...
