Re: MK1 Dragon 32 hardware fault
Yep I'll attach the Eagle files Gerber files........ Please note you will need to break IC13, pin 11 from the circuitry on the D32 mainboard (either by cutting and bending the pin, or cutting a track on the mainboarrd). Gerbers : D32VidFix1.10 - Gerbers.zip Eagle files : D32VidFix1.10 - Eagle files....

Re: DIY-Project for USB/SD/Floppy connection
Is there a DIY-Project (maybe on Github...?) for a Device to load programs/games from USB, SD or a Gotek Drive ? Yes, I´ve seen that there are several Devices like CoCoSDC or DragonMMC, but they seem to be closed source and I could buy them here or there, but I would like to build something on my o...

Re: Dragon 32 with DRAM removed, video output?
Yeah, I replaced all the fuses with 3 amp. Caution from the PSU board designer...... 3A is probably ok on the 5V and 12V lines (the 12V is just passed through anyway), and the 5V reg is rated at 3A, though it will get hot, if you draw 3A from it! However the -5V/-12V circuit is only good for 750mA,...

Re: Fried DragonMMC, please help!
Hi, You should be able to test the vreg if you power the board up, one of the end legs should be 5V, the other 3.3V (centre is GND). If there are no LEDS lit, then chances are the AVR is not getting power, as part of it's powerup routine is to check for the card, and mount it, which should blink the...

Re: DragonMMC Out of Memory with CoCoVGA
I've seen this with DragonMMC when the edge connector is dirty / not making proper contact with the socket in the Dragon.
Try giving both a clean and see if things improve.

Re: D64 with new Dragon PSU issue
Hi all, As the 'designer**' of the new PSU board I'm perplexed too. My first instinct with the D64, would be to temporaly remove the Plus board and test as a stock 64. Though I don't see any reason why it should not work with a Plus equipped D64. Not sure on the DragonDrive problems, do said VDKs wo...

Re: Atom RGB port?
Hi all, If it's the one that plugs into the 6847 socket, I did design an adaptation of Hogelt's board for the Dragon (and the Atom, but Atom version is more problematic). The later version also integrated the Dragon 200-E character generator that JohnW reverse engineered. It worked reasonably well, ...
