Re: Relocating MTX Machine Code

Nice Bill. It could also check if it is on a machine it was already recompiled on and skip the relink. Some commercial software would load a block of code at 0x8100 from a basic loader to get around the problem. Some would stuff it into an ASSEM line with a bit of code to copy it 0x8100 before runni...

Re: New tape cleaner tool

Wow Bill, thats an amazing piece of work.

That is at least one commercial MIA that I know of recovered.

As for Interrupt, unfortunately these wavs are just files I accumulated from various places so I don't know what they are meant to be.

Re: New tape cleaner tool

What would be read? In normal operation an interrupt is triggered on an edge (can't remember which on). Would not the bit read just reflect if an edge has been detected or not? As an aside, one of these days, when the emulators are up to it, I would love to write a tape loader with music and loading...

Unconverted mp3s

Hi all, I have a number of mp3s that I have discovered over the years that I haven't been able to convert. Now might be a good time to see if, as a group, we can do it now. This first list are working mp3s, i.e. that load correctly into a Memotech however I've not been able do that with my setup. Ji...

Re: New tape cleaner tool

Here are some calcualtions that might help: The MTX tape routine works by configuring the CTC to interrupt on edge detection. While waiting for the edge, register A is decremented. No of cycles to execute "DEC A ; JP C, -3" - 14. It takes 14 cycles to decrement reg A. 22050 sample rate is 4E6/22050 ...
