What is the next "step" in my education?

Hi all,
First off, thanks to everyone that has been a huge help to me so far!
I have decided to focus on my CoCo2 and I have ordered an SDC (SD card reader) and case for it.

Okay, I kind of asked this question awhile ago, but I want to reframe it.
I'm looking for your suggestions on the next "step" in my education...
I have read and worked through the Extended Basic Manual that came with my CoCo2 and found it very
interesting... but I was left wondering what the next "step" is?
Anyway, I have been working through the Rainbow magazines and have been learning a lot, but so many
questions come up from the examples that I read like:
- how does one learn the memory map of the 6809?
- I see magazine examples and think, "why/how did the author know how/where to POKE/PEEK in that memory
location", etc?

- I'd like to POKE/PEEK around and try some stuff, but don't really know where to start, or what is where in memory.

- what is the best way to experiment with more advanced BASIC, PEEKS and POKES, and ???
I have been looking that the following books:
- Color Computer Graphics - William Barden- Ultimate Color Computer Reference Guide and Toolkit - CMD Micro

But I'm open to suggestions.

Thanks and sorry if this is too vague!  

John

Commodore 1084 RGB

Hi

I just realize I have a rgb monitor Commodore 1084.

Do any of you know if it is possible to use it with the Coco3 RGB,
considering the cable is correct?

THanks

Re: The World of 68' micros original prints available? Re: Rainbow Magazine?

Date: Thu, 23 Jun 2016 14:23:14 +0000 (UTC)
From: Salvador Garcia <salvadorgarciav <at> yahoo.com>

Was this publication just printed out using a high quality dot matrix printer?

I looked up 68' WOM and found an issue (Vol 1 no 5) that looked like it was printed on a DMP.

If so then printing out the PDFs would definitely get us the same effect.

BTW: On the issue I saw there is an article titled Support for OS/9 Level II by Robert Gault. Now, where have I
heard that name before? :-)
=============================================
Salvador, the magazine was printed on an Apple Laser Writer in the early years, just 300 dpi. The first 2-3
years were scanned in and saved as PDFs, not made from the digital copies. That made them a little grainier
than the last couple years. I just looked at them, there is some difference, but not a whole lot. 

John, I didn't mean to insinuate that you didn't know how to print. I would assume that you have a modern
computer as well as your CoCo, or at least access to one... Would be faster/cheaper to run off on a laser
printer than an ink jet though. Of course you may have one...

Re: [Color Computer] Trying to connect my CoCo2

Modern TVs still have analog tuning capability because some cable providers still broadcast analog
signals. At least my brand new LED TV does, and it has a really good tuner too! :)

Re: [Color Computer] Trying to connect my CoCo2

Please post links to pictures showing the adapter you are using and the resulting screen. If your TV has a 75
ohm coax input I would suggest using a 75 ohm coax cable with connectors like this:

Then use an adapter like this to connect it to the Color Computer's TV output:

I use this setup with my MC10 and used to use it with my CoCo 1 before I installed this modification:

[Color Computer] Trying to connect my CoCo2


 Hi there,
 

 I'm trying to get my CoCo2 connected to my new age TV and running into some trouble.  I have a RF to Coax
converter to plug into the antenna but I see a messed up screen when trying to do this.
 

 I am on the same channel as the computer (tried both 3 and 4) and only see a distorted screen when the channels
match.  Not sure if my computer is not working or the connection to the TV.
 

 Any guidance or things to troubleshoot?  I still have the old game switch but I don't think I need it anymore as
I don't need to jump between computer and antenna.
 

 Thanks,
 Darren

Re: Emulator question?

Thanks Jim,

Yes, right now I'm stuck, I really like both machines (CoCo2/MC-10) and am having a hard time choosing which
one to focus on.

I have found a way to get typed programs from Notepad onto the CoCo via XRoar, so that problem is solved, but I
have to admit that things are more elegant in this department on the Virtual MC-10 emulator in my opinion.

Thanks,

John

Re: FW: CoCo2 lower graphics

That was it.  Swapping out the SAM chip did the trick.  I had to replace the
SN74LS785N with a SN74LS783 chip.  But so far everything seems to be running
as it should.   Thank you a bunch for the quick responses.

Emulator question?


Don’t think that it is easy on any of the Coco editors.  You can use the command line utilities decb.exe to
transfer DOS files onto .dsk, but that can be a little cumbersome.  

Editing in Wordpad and then quicktyping immediately into the Virtual MC-10 emulator is possible and easy. 
So if your programs weren’t involving any hires graphics I would encourage you to come over to the dark
side and use the Mc-10 emulator.  Or if you wanted to you could start up the emulator with the MCX BASIC rom and
you would have 90% of the hires graphics commands of the Coco present in the MC-10.

Anyway, here is a vid of me editing in the VMC10 using Wordpad
