Cheers all that seems to be helpfull.
I have found that adding -timeout 30 is handy for games like "Screaming Abdabs" that don't turn off the tape once they finish loading!
Cheers.
Phill.

Dragon Quicks
Hi all,
Is there a version of the Dragon quickstart archive that contains the same content as the Android phone / wav archive but in *CAS* format. This would be idela for DragonMMC as it can fastload CAS files.
Failing that is there an automated way to convert WAV->CAS?
Cheers.

To clarify on DragonMMC : On the Dragon (or DraCo in Dragon mode). Load Dragon basic file however you want to load it (From real tape, cas file, disk file etc). Convert from Dragon to CoCo Tokens : MRETOKC Save the converted basic program direct to the SD card : MSAVE"filename" The move the DragonMM...

Re: DRAM data retention time
I keep wondering about using SRAM for a memory upgrade after all 512K RAMs can be had pretty cheap nowadays, and you don't have the problem with refresh. However you would have to demux the Z0..Z7 lines from the SAM, and cope with the fact that the Dragon & CoCo designs rely on the fact that general...

OS9
Hi all, Was the disk with the modules that would allow a custom OS-9 install ever released? What I'm looking to do is build a custom OS-9 boot disk with some updated / changed modules (specifically disk and clock). Yes I know about Nitros9, but I'd also like to backport my work to "official" Dragon ...

Re: Dragon Beta
Are both CPU's really running code from the ROM at the same time? Wouldn't that cause conflicts on the data bus? Is CPU#1 ever HALTed? The current code has a comment saying FIRQ goes to both processors, confirmed by your notes, but the old working emulation never seemed to do this. I'll see if I ca...

Re: Comparison of Dragon mass storage options
Does the Dragon MMC come with a case ever, or will I have to make one from Lego? I've uploaded the source for the DragonMMC firmware to my github repository here : https://github.com/prime6809/DragonMMC There is a folder with the FreeCAD source and generated STL files that will allow you to 3d prin...

Re: Dragon Beta
The emulation of the Beta last worked in MESS 0.138, which was 10 years ago! The MAME framework has advanced significantly since then but the Beta driver has been left to rot. I'd really like to get the Beta emulation working again, but will require more or less a rewrite to make use of the latest ...
