It would be nice to have a copy of the Dragon 32 SSTV program (Grosvenor) in the archive as well.

Will try another recoding computer later. Thanks. :) I could have converted it to a ROM image in less than five minutes last night if your wave had been suitable for loading under XROAR Dragon emulation. It may be possible to get your original wave file to load with some fancy audio editing (and ha...

Your wave file recording is not good enough to load under XROAR Dragon emulation. Please save it again, but make sure the wave file will load under XROAR before uploading. Use AUDIOON:SKIPF under XROAR Dragon 64 emulation as a check to make sure the file will load without I/O errors.

Here is a slightly modified version. It does the same job, but is much faster.

A copy of this title (.cas format) has already been uploaded by robcfg on April 15th, 2012. It was dumped from the original cassette, and tested on XRoar and a real Dragon. He was also kind enough to take the time to create a nice wiki page with good quality pictures of the original inlay card, full...

Thank's for keeping us informed. I have just uploaded a couple of different copies of the program to the Uploads section along with the instruction manual. I'm looking forward to your write-up. :) The RTTY CAS file you have linked to at http://www.dragon32universe.info/ can't currently be downloaded...

Attached below is a copy of the G4BMK RTTY program by Grosvenor Software. This title is already in the archive, but is marked as underdumped.

Here is a program I wrote for recovering BASIC programs that have been deleted by accidentally entering NEW before saving a copy to cassette or disk. The program is compatible with all CoCo and Dragon machines. It will also work on a Dragon 64 in 64K BASIC mode.

Listed below is a quick example of how to enable and disable the 15700 Hz Horizontal Sync Interrupt on a Dragon 32/64. 10 ORG $5000 20 ORCC #$50 * Disable IRQ/FIRQ interrupts 30 LDX #ISR 40 CMPX $010D 50 BEQ DISBLE 60 ENABLE LDA $FF03 * Disable Frame Sync Interrupt 70 ANDA #$FE 80 STA $FF03 90 LDA $...

How should I proceed if the part of code is much larger (in time) than the updating of the text screen in your example? Do your best to work out a compromise. :) How could I know that the 'bonus' time has finished without using interrupts? The time period is always exactly the same (remember that i...
