Pere, you wondered if you are the only Dragon user with physical floppies, a CocoSDC and a MultiPak. Maybe you are but I will receive my CocoSDC soon and I do have a Race-electronics kind of Multipak for the Dragon ( http://worldofdragon.org/index.php?title=RACE_Computer_Expansion_Cage ). When I ge...

Well you can grab these ones. MESS emulates Dragon Plus if you don't have one Thanks a lot! I own a Dragon-Plus and I had used it quite a lot back in the 80's but by now it is in John's case waiting for me to install it someday. By now I am far too busy with my MSX2+ project for the CoCo-Dragon mac...

hello,
pleased to hear from you again!
Any link for anyone interested in NitrOS-9 for the Dragon-Plus?
thanks beforehand

we are happy enough to have a hardware guru like Darren Atkinson helping us to solve awkward problems Thanks a lot, Darren, you are vey kind!! cheers By the way, I could not resist and have taken two resistor arrays of 4k7 and a std resistor 5k6 .. the only components I have right now and have added...

Hello John, sorry for the delay, but it has been impossible to take the photos earlier ...

with 256x424 pixels resolution
cheers!

Hello John, this is strange, I have not this problem. What mode where you looking at? Let me know and I will try it tomorrow... The best images use to be for BASI12 which uses two frames for each image. But the other resolutions give very acceptable images too and no vertical noise bars at all ... c...

hello, just to give a little hope to Dragon-MSX2+ users ... Mike Miller has found that the SDC firmware activates FIRQ for next byte very fast (10usec) and he would like to have the chance to double this value just to see what it happens ... So, I have contacted Darren Atkinson telling him Mike's id...

oops, I have tried to start the Dragon with the MSX2+ board connected but without power supply ... The Dragon goes mad and fills the screen with garbage. No way to start in this setup, so the pins from the MSX2+ module without power supply do not have the expected level and are pulling to the wrong ...

Hello, I have done a first try changing the DP50E read sector routine, I have tried copying the ROM to RAM and then inverted the lda and ldb to acknoledge the interrupt first place. I have changed the cmpx to three nops and then modified the branch to be a BRA But loading a program to play some VGM ...
