[Coco] FW: Green mountain micro color burner

Mon Sep 16 19:57:42 EDT 2013

Hi Everyone!

Everyone who is interested in this project, please send me a private email
so we can determine who would be appropriate for hardware diagnostics and
testing for this project.  

I do have an idea for a power supply for this project.  I have some 24V
center-tapped transformers that would work very nicely for a simple 27V
power supply.  I've been sitting on these transformers for over a decade!  I
always say that if you hang on to parts long enough, they will become useful
. eventually.  J  

No plans at this point for any software changes.  If anyone has any ideas
for additions or upgrades for this project, please let me know.  Once I get
a handle on who all is interested in getting involved in this project or who
just wants to get one once the development is completed, we can work out
further details.  Thank you all in advance.  Take care my friend(s).

Kip

Hey,

Did you forget that I live up north here in Quebec ? There is on ABRA
Electronics branch here in Montreal and they seem to have the PIAs and other
components. 

Yes I can assembly but I'm a software guy, finding bugs on the PCB would be
too much for me. You need at least 3 PCBs, Daniel Campos in Brazil is also
interested in this project too in one although for him it would be hard to
find the PIAs.

As suggestion what can we use in place of the 9V batteries since they seem
to drain too fast?

Other nice project would be the lowerkit, i just love using my coco1 and
having lowercase would be great :)

Hi Luis!
I have now entered the schematic for the Color Burner into my laptop and
have created an initial PCB layout.  Would you be willing to build one and
be my first official tester?  I have to buy 3 PCBs when I have a prototype
PCB fabricated anyway.  I believe my entered schematic is exactly like the
original schematic in the color burner manual in every detail.  Shipping a
PCB to Brazil would be a lot less if you already have most if not all the
parts on hand since it sounds like you are a hard guy like me.  Also if you
have any ideas to make this recreation better than the original, please let
me know.  Since it is in the public domain,  I'd like to eventually reissue
this project in kit form or sell the new PCB to anyone who has similar
interests in hardware projects like us.  Thoughts, Ideas?  Please let me
know.  Thank you in advance and take care my friend.

it would be great to have a pcb for it Kip, but what about the personality
module?

is it just a wired socket or does it  have ony other component on top of it?
couldnt this be replaced by a dip switch?

i just want an affordable a 24pin eprom burner for my personal projects here
but only very expensive xeltek burners can do it.

Hi Luis!
Inspired by your question I think I will tell the story of how my version of
the Color Burner came to be a reality.  In the meantime, how it all started
was I came across an article for my version the Color Burner and built mine
about 3 decades ago on a Coco Prototype PCB that Radio Shack use to sell
back in the Glory Days of the Coco computer line.  I honestly don't remember
how I got the software running from disk, but I did come across the DECB
floppy disk a while back and read it into my workbench PC a year or two ago.
After looking at the Color Burner manual PDF last night that Al Hartman so
kindly and generously had scanned (at great cost I might add) I realized I
needed to look at my homebrewed Color Burner PCB again, for I don't remember
using any 6821s in it.  What this means is My version of the software may or
may not work on Dennis' original PCB design as I might have modified it or
it might be another completely different eprom burner altogether, so I'd
like for someone who does have Dennis' original version to test this theory
from me and let me know by private email the results.  I certainly DON'T
remember much of what I did back then.  Recall after long term storage has
always been difficult for me at best.  I'm actually speculating much of what
I might have done.  When I found my Color Burner hardware, I was wondering
what two eproms my two 16-pin header personality modules were wired for, so
when I saw this discuss begin on the Green Mountain Micro Color Burner  I
decided to participate.  I'll need to look at my Color Burner PCB project
again, because I absolutely don't remember using any 6821s at all.  Weird
how something you built almost completely escapes your memory.  And I
thought my memory was non-volatile!  :)   As to your question of PCBs, I
don't have any other PCBs for the Green Mountain Micro Color Burner as I
made only the one.  After all, once I built it, I didn't need another one
and back then I did not know how to go about making my own PCBs though I
thought about it from time to time.   I can enter the schematic and layout a
PCB for you if you'd like.  I don't think Dennis would mind since he
published the article those so many years ago anyway detailing the whole
with software to boot.  Thank you Dennis for sharing your design.  I really
appreciate it.  I never in my wildest dreams thought I'd ever be able to
communicate with you personally.  Luis, I'll get to work on it right away.
How I built mine?  I point to point wired it on the Coco Prototype PCB from
Radio Shack and now that I think about that PCB layout, it was not pretty
nor professional, but it worked for me just fine!  :)  I used it quite a bit
for a while helping various members in the Spartanburg Color Computer Club I
use to belong to in Spartanburg, SC before I went into the Air Force in
1986.  I had a lot of fun with it as I recall.  Well, I better stop this
email as it is getting long and you guys know how I enjoy sharing my
experiences.  Take care everybody.  Happy Eproming!
Kip

Hey Kip,

Do you have any other PCB for the green mountain micro burner ? I would be
very interested in assembly one for me :)

Looking into the manual, it has all the schematics there, but how did you
make your PCB ?
