Re: 2 Button Joystick?

Yes, it does have 2 buttons.

Re: CoCo MIDI

If you configure Drivewire 4 you can use a PC as a Midi device, and I think you can also wire a midi cable to the 4
pin serial port.

GBS-8200 RGB to VGA

  So before I found out this was a bad choice, I ordered and paid for 
the cheap Chinese RGB to VGA converter board.
  While waiting for it, I began to learn that the H signal from the Coco 
is inverted and an inverter chip will be necessary to correct that...bummer.
  Then I read that another fellow was connecting a Coco 3 to an SCART to 
VGA converter board and he found the same problem with the inverted H&V 
signals from the Coco. He used the Video out and mixed them for the 
SCART to use and it worked for him.
  I tried something like this on the GBS8200 but I only put the video 
out from the Coco on the H line on the converter.
  It works beautifully in 32 and 40 column modes but the 80 mode does 
jump up and down a bit. Otherwise it is great looking.
  Tomorrow I'm going to play with it some more but, this looks really 
promising. I've simply connected the video out directly to the H input 
on that converter. Next I'm going to play with levels and resistors and 
caps, I might even play with the vertical line also but, I have a pretty 
good feeling this GBS 8200 is going to work just fine.

Re: 2 Button Joystick?

I keep reading about CoCos supporting 2 button joysticks, but I have yet to even find an example of one.   I've
seen the typical RS black one button type, which is what I have.   I've also seen a "deluxe" which is beige and
has a button on the top.  Can someone point me in the right direction here?

Or does the deluxe seen here [

Hard drive interfaces

I have been looking for a hard drive interface for a while. I know Cloud 9
used to make one but now does not.  I have a slew of old IDE drives sitting
around on the shelf. If anyone has an IDE interface they might be willing
to sell please email me directly.

CoCo MIDI

I was looking on the CoCopedia website and saw a hardware device call CoCo
MIDI. Does anyone know about this device or even have one for sale?  The
wiki article is nonexistent. I been wanting to get more into MIDI and have
been looking for MIDI hardware for my vintage computers.
Thanks,
Mike

Thanks

I just want to take this time to thank everyone for being patient with me.  Lately, I've been asking a lot of
questions and I'm sure sometimes they can be taken a little differently than intended. As I mentioned in an
earlier post I have been away from OS9 and the CoCo for some 22 years now and I find it very refreshing to see
that everything is so well supported by knowledgeable people as yourselves.  Just the fact that we still
have a viable replacement for the OS9 system after Microware's demise is testimony to the hard work that
has gone into the development of NitrOS9.  I also certainly appreciate all of the tools that have been
created to support the system, like Toolshed and Lwtools.  Soon, I will adopt these tools and learn how to
use them as I can see that they are very useful.  However, I have some reasons (not merely because I'm
stubborn!) for trying to get some of this development working natively from NitrOS9.  I have some projects
that are more of an embedded nature and I plan on using some equipment that will be 6809-powered but not
necessarily by a CoCo and now, not even necessarily by a 'real' 6809.  Being able to make changes on the fly in
an environment where moving information back and forth from a PC is not practical is important to me.  So
please don't take any of my questions or statements as an affront against anyone.  On the contrary,
everyone who has contributed to this effort is worthy of praise on my part.  I just hope that eventually I can
give something valuable back to the group.

A couple of my near term goals are to try to get my CoCo3 FPGA untethered from the PC and to implement a version
of Level 2 NitrOS9 on a modified Multicomp project.

NitrOS9 booting sequence

Ok, so as everyone has probably figured out I am trying to make some 
modifications to the REL, Boot, and Krn modules in order to get the 
CoCo3 FPGA booting directly from the SD card without help from DW.  I'm 
also trying to accomplish this with native tools under NitrOS9 instead 
of using the Toolshed and Lwtools packages. So, today I was able to 
create a boottrack file and svdgen a disk.  When I try to boot it the 
screen shows all of the modules loaded through Clock2 and then at the 
end it prints  "i2xo*X" just before the boot fails.  I'm guessing that 
something is still missing on the boot disk.  I have an OS9Boot file, a 
sysgo file, and a CMDS directory with just "shell" in it.  What am I 
missing in order to complete the boot?

lwtools assembler difference

Well, in my comparison of the code generated by the lwtools assembler 
and the stock OS9 assembler I have found a quirk of the lwtools 
assembler.  I won't call it an error because it appears that the outcome 
is not affected and it seems to be a minor thing.  On every other 
assembler I've used including AS6809, CSC6809, and the stock OS9 
assembler the following assembly source:

ldb  ,x
  or
ldb 0,x

is assembled in machine code as:

E6 84

which is the indexed addressing mode with no offset
However, the lwtools assembler (evidently) assembles in machine code as:

E6 00

which is the indexed addressing mode with a 5-bit offset with the offset 
being zero.

I dont have a copy of EDTASM anymore so I can't say how it would 
assemble it.  This just seems to be the case of a smart assembler which 
determines the given offset to be zero and thus translates it as a "no 
offset" postbyte as opposed to a "5-bit offset" postbyte.
