EDTASM+ for the Dragon 32/64

Attached below is Radio Shack's EDTASM+ which has been converted for use on the Dragon 32/64 by Stephen J. Woolham. A copy of the original EDTASM+ manual is included.

The most powerful assembler ever written for the CoCo 1/2 is now available for the Dragon. 8-)

DragonDOS/SuperDOS uses memory from $00EA to $00F8, and from $0600 to $0BFF.
simon wrote: is the irq vector at $10c like the coco ?
Yes. The secondary interrupt vectors are exactly the same as the CoCo 1/2.

Re: Tools for converting Dragon DOS <-> DECB and CAS->DECB

I think reading from stdin on Windows needs special attention. stdin is by default opened as a text stream, so various conversions would happen on Windows. Try adding this to the top of main(): freopen(NULL, "rb", stdin); EDIT: Added to git Its still not working correctly. C:\cas2decb <formx9.cas >...

Re: Tools for converting Dragon DOS <-> DECB and CAS->DECB

It compiles OK now. But its not working correctly. C:\cas2decb <formx9.cas >formx9.bin Program "FORMX9 a?@" loads at 0x3F00, execs at 0x3F00 Could not read next byte after offset 0x02E6 The modified source code and compiled win32 binary are attached. EDIT Attachment (cas2decb_test1.zip) removed.

Re: Tools for converting Dragon DOS <-> DECB and CAS->DECB

Thanks, Tormod. :) The only one I can't compile with gcc is cas2decb.
cas2decb.c:24:17: fatal error: err.h: No such file or directory
compilation terminated.

Re: New 1bit PWM music engine for the CoCo and Dragon

so now i have come up with a couple of VU meters incorporated into the routine..... (these use text mode block gfx).... i have no idea if the "normal" screen on a dragon starts at $400 ???? - my coco II (no dos) does, so the meters are plotted at $420 / $460..... change the addresses to suit I like...

CoCo 1 vs 2 detection by Darren A.

The following text was copied from the CoCo mailing list. I think I may have found a way to detect a CoCo1 vs a CoCo2. At least it worked in the very limited test of the two machines I have. Rather than look for the SALT chip it tries to detect if the machine has the custom integrated DAC chip. The ...

Re: New 1bit PWM music engine for the CoCo and Dragon

sweevo is for "the music box" not "the music studio"..... I know. it sounds allright in music studio on beepola, but you probably need to halve the pattern tempos for it to sound allright on the coco/dragon player.... I did halve the pattern tempos. I think sweevo9 sounds pretty good. But I'm NOT a...

Re: New 1bit PWM music engine for the CoCo and Dragon

Yes. But they are mostly the same songs.

Here is one that I downloaded from the other (ftp) link you posted. The v9 engine is included.
