Use the expansion port to host VDG character ROM? In short, not a chance.

Yeah, I have a standalone Flashfloppy unit from Zaxon too, and I've used it with the Dragon. I've used 3.5" and 5.25" drives as well. I gave in and added a column for HxC / Flashfloppy / Gotek units but seeing as you need a Dos Cart anyway, for most people it'll be 'Well, where do I get a Dos Cart t...

I've added in a generic Drivewire option (uDW or PC server) now.

Gotek or Flashfloppy standalone I'm a bit cautious about adding in.

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.

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

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.

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.

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...

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...

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...
