Interesting Stew - so have you added a ear and remote socket, and made the uDW play out the cassette loadable Drivewire dweeb?
I might try to add in a drivewire column.

Comparison of Dragon mass storage options
Phil H-S suggested a comparison between the various mass storage options available for the Dragon would be worthwhile. so I've created one.

Re: MAME Emulation - 80 track double sided
Compiled mame 0220 the other week. Still appears to be a problem with Soren's OS9 double sided disk booting, which works fine on a real machine, on Xroar, on multiple drive emulation mass storage solutions.
Something is definitely wrong with Mame's floppy subsystem for Dragon 32/64 machines.

Re: Dragon power board problems!
Interesting measurements Stew! I assume those were all bare-machine, no disk interface and on factory original 4700uFs?
The TO-3 packaged switch mode converters ... this looks like them...

Too tempting not to try, have ordered a couple.

Re: Dragon power board problems!
I'm inclined to agree with Mr. Orchard here... measurements under load are key. I don't even know what some of your franken-dragons might draw on the 5V line, but on my oldest, most heavily used and customised machine power up is unreliable (won't boot, works after reset) with its original power boa...

Re: Debugging a real Dragon with NoICE - serial port
Hi Pere, I think it's probably most useful for real hardware scenarios, as you say. I have been looking for a real hardware options for some time, and this looks useful. I understand also that there is a Nitros9 module, though whether it can work in L1 may be an issue, but it's a very interesting pr...

Re: Debugging a real Dragon with NoICE - serial port
I just came across this thread... wow, another excellent Dragon tool! To make it even more worthwhile, the NoICE author loves the 6809 and 6309 so much that, unlike every other CPU the project supports, he will offer the license for 6809 and 6309 for free if you simply email him and let him know abo...

Re: A next-generation Dragon?
The main parts of a next generation Dragon are effectively in existence right now... A 6309 machine, with CoCoSDC and V9958 based Graphics. Keeping the SAM/VDG keeps backwards compatibility. Add something that gives CoCo3 style paged memory capability - like Tormod's MOOH, or the still vaporware CoC...

Re: Using the Wordpak2+ on the Dragon
Yeah, Wordpak 2+ and multipak emulation for the Dragon in Mame will be nice wins. Thanks Pernod!

Re: Dragon64
This is interesting - I have a Dragon 32 which I've just acquired that displays EXACTLY the same symptom.
It boots normally, then after a very short time, the screen instantly changes colour set and clears.
Haven't had time to investigate further, certainly a strange one.
