Re: WTB Dragon and game carts

$49 for the Dragon and $90 for shipping :cry: They say a package weights 19 pounds (= 8.6 kg), so shipping is expensive. Shipping starts September 16 and my Tano Dragon arrived today. It's DOA -> http://archive.worldofdragon.org/phpBB3/viewtopic.php?f=8&t=4393 On the USPS form stands "Total Postage...

Tano Dragon 64 NTSC to PAL ?

My Tano Dragon arrived. But it's DOA :( I heard a clatter. So i open the case and the clatter comes from the Tano Dragon. So i open it. The 4700µF 16V capacitor had come loose. See pictures. I will solder it him again. IMHO was the problem, that there was no fill material in the transport box. The n...

Ah! Good hint. Thanks!

Re: Howto setup Slim SD HxC Floppy Emulator ?

From http://dragon32.info/info/drgndos.html : 3.

Re: Dragon emulator written in Python ???

I have worked more on the "code generator"... The generated code skeleton looks now like this: class CPU6809Skeleton(object): @opcode( # Add B accumulator to X (unsigned) 0x3a, # ABX (inherent) ) def instruction_ABX(self, opcode): """ Add the 8-bit unsigned value in accumulator B into index register...

Re: 6809 opcode missmatch...

If you don't have a copy of the "MC6809 Microprocessor Instruction Set Summary" card (where it's shown as "60 NEG INDEXED 6 2") you can download a copy from the forum . Thanks for the link. This PDF is new to me. The wrong information: But in http://www.maddes.net/m6809pm/appendix_a.htm#appA stands...

Re: Dragon emulator written in Python ???

I enhanced the scraping scripts with: https://github.com/jedie/DragonPy/commit/c0e2a4e56c1043613693965ff15fa1ec04c4f6b6 Now i merged the informations from the three sources.

6809 opcode missmatch...

This opcode line:

Code: Select all

 | 60    0096 | NEG         | INDEXED      |   6   |   2   | uaaaa |
says address mode "indexed"... Thinks that's right.
But in http://www.maddes.net/m6809pm/appendix_a.htm#appA stands only Inherent, Extended, Direct

Maybe the error is in the origin Reference?

Re: Dragon emulator written in Python ???

I will start a new implementation. I hacked some data scraping scripts: https://github.com/jedie/DragonPy/commit/79e0b749ca71f97534da8eec2d83265f6e75d903 These script will collect information from: http://www.maddes.net/m6809pm/sections.htm#sec4_4 http://www.burgins.com/m6809.html http://www.maddes....
