CLOCKSET

Further understanding of the inner workings require disassembling the code.

Do you know if it's possible to run the compusense DISM on XRoar and disassemble the ROM image

The cartridge has a 2KB rom and it boots with XRoar

I've attached the rom file and a screenshot.

Cheers,

Yes thats the screen I get when used in a real Dragon 32 or 64.
Is there any way of getting data from the rom file that would help with the functions and syntax

If needed I can provide you with an FTP address you can upload it to.

Thanks!

Forum won't allow wav files, could you send me the ftp

That's too long. It should be at most a couple of minutes (give it 3 or 4 just in case). Try repeating the process but with this call instead: CSAVEM"MTXIO",&HC000,&HFEFF,&HC000 As reading from the last 256 byte block may cause it to hang because it's the I/O control block... Yes that sorted it, do...

That's excellent! The process is really easy. You just need to connect the audio cable for loading tapes on your Dragon, and connect the audio out jack to your PC's audio input, which is usually the light blue one. Open Audacity, select the right input source and set the recording volume to somethi...

I assume the outputs will all have the same ground point, so you could look to see which of the 16 output terminals are connected. Each alternate one on each side no doubt. Obviously not connected to the Dragon when testing. That might then allow you to work out which pairs are ports, and you could...

Robcfg I think I have the necessary cables and a copy of Audacity on my PC, just need you to step me through the process because it's not something I've done before. It should be similar to when I dumped the ROM from the DASM/DEMON cartridge - see Steve's (zepher) instructions at https://archive.wo...

The Dragon User Magazine, page 12 April 1986 shows a bit about it along with a short program listing. I'm still hoping someone out there can shed more light on a user manual.
