6809

in General Discussion
In another thread someone mentioned that they still enjoyed playing with the Motorola 6800. I used to have one of those as well and also the 6809. Unfortunately, I never had the time to do much programming on the 6809 and I no longer have the system either. I've been looking around for a 6809 SBC and I found this one. This company seems to have "trainers" for a number of different processors including the 6809. Has anyone used one of these?

    Those kits look pretty good. A lot of documentation and monitor listings.
    Looks like you could also get a Kim-2 look a like (6502)

    The 6802-6809 is going to be like the Heathkit trainers.

    I'm curious to why he only sells on board at at time. To achive the keyboard look in the ebay add, you have to 3D print a keyboard spacer and print out the overlay; after soldering all the pushbuttons.

    Lots of CoCo's for under $100

    I know about the CoCo but as far as I know only the CoCo 3 has a composite video output. The others just have RF which makes for a bad image.

    I have a number of 6502 boards. Some even have Propeller chips on them. One is even signed by Woz! :-)

    You have several FPGA boards as well, right?
    you might want to look at this: http://searle.hostei.com/grant/Multicomp/

    I know about the FPGA emulations as well as software simulators. That's one reason I haven't bought one of these 6809 boards. I'm not sure what it would buy me beyond what I can get with a software simulation. I would probably have bought it if it was a kit because I like building things like that but this one comes completely assembled.

    searle also has a pure hw design:

    But you'll need a pcb yourself.

    can use a prop board with ps2 and vga ad io board :)

    Even better than a kit! I get to make my own PCB. Maybe I'll try it if I can get the Propeller board that I just designed working. That's a big "if" too! :smile:

    I bought one of these in the Z80 flavor. Fun to play with and I picked up a nine volt auto adapter so I can use it in the car.

    On the subject of old processors, I just bought an Altairduino. It's the front panel of an Altair 8800 backed by an Arduino Due programmed to function 99% like the Altair. Lots of fun flippenswitches and blinkenlights.

    The Altair 8800 is way to modern for me. I built this one a while back.

    Oh my, this was a dangerous thread to read...an Altair, a PDP...how can I pick just one??

    Recently obtained an old dvd player for experimentation and redesigning. I still need to figure out the comm protocol for the screen.

    The Obsolescence website? No, I'm just a customer. I did put myself on the waiting list for the PiDP-11 kit though.

    Oh for...... **Wanders away grumbling in Martian. Again.** Sorry Doctor Who is guest writing this one.

    The same guy also does a PiDP-8 kit. I met the guy at the VCF East event several years ago. I also caught site a <BLEEP!> lot of actual PDP style systems.

    For my part I also looked at the trainers that are a part of this thread for something else.

    As for your DVD Player idea, there's an interesting thread someplace else about repurposing them, depending on its name you should get a good hit someplace.

    I recently got an old LASERDISC player and a VIC-20. The Laserdisc player is awesomely complicated and the video is Smile by today's standards, as it's basically an analog NTSC stream. I am pretty sure there is an actual helium-neon laser tube inside it so I may just take it apart for geegaws.

    The VIC-20 was an impulse purchase, the guy had it basically new in the box for twenty dollars, including several game tapes, the cassette recorder, and some blank cassettes. VIC-20 unboxings aren't unknown on teh interwebs but I'm not sure exactly what I will do with that package either.

    I love laserdisc. Its big, beautiful media.

    I am not sure what I would do with a VIC 20. A C64 can render a useful display. Terminal, etc.. the VIC 20 is just under what I find useful and interesting.

    Maybe play slme Omega Race, or Gridrunner? Some VIC 20 games are surprisingly good, considering what the machine had to offer.

    Its BASIC is fast too, FWIW. There was little demand from the video system inhibiting performance.

    David Betz,

    Ahhh, the 6809 was my first love.

    A colleague and I built a 6809 SBC with all the usual RAM, ROM, PIA and serial interfaces. No hex display or keypad, we had a VT100 terminal for it. Even built a cassette tape storage interface for it. All wire wrapped.

    Creating the the monitor code for it was a challenge. What with not having an assembler we had to write our code in hex for the EPROM programmer.

    That turned out not to be so hard given all the creature comforts of the 6809 instruction set for the assembler programmer.

    Later I build a little 6809 SBC, with hex display and keypad, from a kit. Explaining that to my girlfriend at the time inspired her to get into programming and mathematics. She left me to pursue a degree in maths. I was miserable.

    Damn that 6809!

    Maybe there's a song in that. "I lost my heart to a 6809". If it becomes a hit I get some of the royalties.

    Another Omega Race fan? I have the rare cocktail table version in my garage. Monitor needs caps.
