Re: smoking dragon
As Alastair said, looking visually is a good place to start. There are probably some people on here who would take a look (I'd have a go) but there'd be shipping costs etc. It may or may not be repairable, it's hard to say without investigation. As you're planning on selling it anyway, if selling it...

Re: WTB Dragon and game carts
Just got to get it to work now... It confused me a bit, because the "power switch" isn't. It's a TV channel select switch. The power switch is on the transformer box... I think it's working - my logic analyzer shows the 6809's address bus doing reasonable things - but I can't get video out. I've got...

Re: WTB Dragon and game carts
I've just received my Tano Dragon 64 from the California Digital - so they definitely hadn't sold out.

Re: Stuff found
I've just uploaded a dump of the ROM from the disk controller to the upload section

Eurohard Dragon DOS v4
This is slightly different from the one in the download section. It came from a 'Cumana disk controller' (http://archive.worldofdragon.org/index. ... gonDOS_FDC)
It seems to be mostly the same as the v4.0 ROM in the download section, but with Spanish text

Re: Dragon 32 "Quick Reference Guide"
I can't remember, but there is a bit of similar card with perforations in my BASIC manual which looks as if something was removed from there. The Quick Reference Guide is too worn to be able to tell if the perforations match

Re: Utility to convert Anadisk "dumps" to VDK
Most of the 'machine that is changing' stuff should be handled by the OS, not the application software.
It seems that most of it just because the linker/run-time-library authors just don't care. What is an extra 40-80kB or so on Windows nowadays?

Re: XRoar wish/patch info?
I would suggest Python :P Ugh. See: these benchmark results Lua is almost the fastest interpreted script language - Python is almost the slowest (only Bash is slower) Also, Lua is tiny, written in C, and specifically designed for embedding - Python isn't :-) There's a reason games like WoW use Lua ...

Re: Utility to convert Anadisk "dumps" to VDK
Not quite - most 80x86 opcodes are still 8 bits wide. Some are 3 or 4 bytes wide (with prefixes etc) but those are the rarer op codes (some 6809 op codes were 2 bytes wide). eg. ADC AL,02 is 14 02 Some of the operands will be 8 bits wide, but only if you're using 64 bit values. The biggest problem i...

Re: XRoar wish/patch info?
It would be cool if the cart code was able to assert EXTMEM/DSD, but I do realise it's probably not widely needed and it could affect performance. I don't know how tight performance is - I guess it depends on host PC's performance. If it affects it too much, I guess you could always have conditional...
