Re: Write binary data to TRD from ASM

Neither Rodionov's book nor the disassembly mention that one (I don't even see it listed as a TR-DOS variable), although it's possible to trace where the check occurs in the disassembly. Well, there’s this , which describes the variable at #5d10 as “MSB of TR-DOS error code, cleared on 15616 callin...

Re: Write binary data to TRD from ASM

The online text is on your link is correct, but the download is linked to the wrong book, ha. Whoopsie. Didn’t notice the download link at all. Anyway my asm calls aren't working, even Hikaru's reference asm load example. My basic calls work fine. Mating calls of other species are notoriously diffi...

Ha, thanks! That's the one I have. I translated the TOC (and the first 20 pages), and I think there is nothing about TR-Dos at all in this book. Even the cover says "ZX Spectrum for users and programmers, no mention of TR-Dos.

Re: Woot! ZXMAS Tape Magazine 2017

Neat! I love cover and the font. I disagree that 2017 has been a stinker of a year for the Speccy. For starters, we’ve solved the mystery of the floating bus on the +2A/+3. That news could have made it to the front page of The Guardian , if only I’d remembered to return their call. (It was a busy Tu...

I’m also quite confused. Is it compressing the data or simply puts machine code inside the BASIC loader? Because you can do both with many assemblers already.
puts machine code inside BASIC loader. What assembler do that?
zasm, for instance.

Re: 128k paging BASIC loader

Thanks Andy. I’m playing around with your Mojon loader adapting it to TR-Dos. Seems a little convoluted to me, switching back and forth between BASIC and custom machine code. Like I said earlier, I recommend you write a small MC loader and stick it into BASIC. Then run the whole thing with RANDOMIZ...

Re: Q*Box, by ThePope (3D game with AGD)

Interesting. Taking the notion of “game over” to the next level. Tried the 48K version, and when you lose all your lives, the computer resets.

Re: 128k paging BASIC loader

Is there a magic way to: be in 128K basic run a program call m/c from the program in that machine code, do the m/c equivalent of OUT 32765,17: POKE 23388,17 Frig the sysvars and stack (somehow) to... return to 48K basic, with your program still running, without resetting ? That’s a tall order, brot...
