Introduction

• First and foremost, I would like express my gratitude and appreciation to Allen Huffman for extending an invitation to me to host my personal web page on his Cocopedia web server.
• I invite you to check back periodically as I document my experiments with my Coco 3 setup and my 6809/6309 microprocessor computer projects.

Let's turn the time machine back to about 2011. I had been looking for work for about three years. One day I decided in addition to that, I would go back and explore my computer roots. Now let's really turn the time machine way back to about 1982. In the early 1980s, my first computer was a TRS-80 Color Computer 1. It had 16K of RAM on an F version motherboard that I later upgraded to 64K. I did everything I could to find out information about that little machine. The internet certainly did not exist back then. It fascinated me and held my attention for hours on end. The only printer I had at the time was an ASR-33 Teletype with paper tape reader and punch. I don't remember whether I started out with Color Basic 1.0 or Extended Basic 1.0, but either way my primary storage medium was cassette based only. Boy, that cassette machine was a challenge to work with!  :) Later on I eventually upgraded to a Color Computer II. The keyboard on this machine was a lot nicer, but the key layout was exactly the same and it came with 64K of RAM! Somewhere along the way I started experimenting with OS-9 LI v01.00.00 or 01 and for the first time I felt like I could really do something special with this machine. Spinning the clock forward a little ways sees me purchasing my first Color Computer 3. Whether the label was TRS-80 or Tandy, I don't remember. All I know is it had 128K of RAM! Now I really had a great and mighty computer in my collection. Also, sometime along the way I started using 5.25" floppy drives and eventually I had a Seagate model number ST-225 20MB MFM hard drive running OS-9 LII v02.00.01 on a Color Computer 3 with 128K of RAM with a Winchester 8-bit hard drive controller card from Burke and Burke. Then the IBM PC revolution began and my computer interests migrated to building an 80286 based PC and I left the Color Computers behind forever, or so I thought. It is now 2011 and I have decided to build a 6809 microprocessor based computer of some sort. I had never had the opportunity nor the resources to build a SouthWest Technical Products Company computer. A close friend of mine used a Motorola Exorciser running an MDOS operating system. It booted into a monitor program called ExBug and then the user entered a one letter command with some parameter to boot MDOS off of an 8" floppy disk drive. Those drives were huge! The system had two drives and an 8-bit MC6800 Microprocessor ran the whole thing.

My Coco 3 Setup

• Narrative about my real Coco 3 setup will go here.
• Fired up my new Coco 3 for the first time on April 4, 2013. Seeing if it worked after having just received it doesn't count.
• Tested my new HDB-DOS eprom I had burnt a few weeks back in my Disto Super Controller on April 5, 2013.
• Coonnected up two 3.5" floppy drives to the Disto Super Controller and formatted a 720K

My Version of Grant Searle's 6-Chip 6809 Computer

• Narrative about my experience designing and building my version of Grant Searle's 6-Chip 6809 Computer.

Used Grant's 6-chip 6809 Computer as the basis for my very first 6809 microprocessor based computer.

Miscellaneous

• All suggestions for 6809 and 6309 microprocessor based projects are welcome. Please keep them both positive and helpful. *Thank you for visiting my little corner of the Wonderful World of the Coco 1, 2, 3, the 6809 and 6309 microprocessors.
• Qaplah! Shalom! Keep Having Fun!
