    Dude - if I can use this to interface my Atari to my Alesis dm6 digital kit! Heaven. "Have I played my drumset today?" - my basement Atari is setup right next to this:

    Snare and toms have new heads, and NO - the bass isn't stuffed to sound like a cardboard box any more. I really need a cleaner pic - I'll post in a few weeks when my new room is complete.

    Slightly OT, but have you ever heard this girl on youtube? She's pretty good :)

     

    Cool drum set you have there Stephen :) :thumbsup: :thumbsup: :thumbsup:

    All I did:

     

    -connect at 1200

     

    ATB"9600,8N1"
    ATW"your-wifi-sid,your-wifi-pw"
    AT&W
    - reconnect at 9600
    ATI
    shows you your internet config/status

     

    Just confirmed flashing one of my nodemcu boards and trying these commands: all works ok...

    ATI   

Zimodem Firmware v3.4                     
CoCoWiFi Version.                 
sdk=2.2.1(cfd48f3) chipid=1458280 [email protected]                                        
totsize=4096k ssize=336k fsize=1048503k speed=40m                                                 
CONNECTED TO AtariOnly (192.168.1.11)                                     
READY.      

at+config         
OK  

Main Menu         
[WIFI] connection: AtariOnly
[FLOW] control: DISABLED
[ECHO] keystrokes: ON
[BBS] host: OFF
[PETSCII] translation: OFF
[ADD] new phonebook entry

Enter command or entry or ENTER to exit:

    After flashing, I pressed the reset button on the board and ran hyper terminal in windows @ 1200 baud. The debug code was sent first, then a 6 second pause before showing the correct info. With the ESP-01, I might not have waited long enough before to see that message. Will now try flashing the ESP-01again with zimodem and see how it goes...

    I like to think of the Apple II as a great training computer. You used it at school to play Wavy Navy and Hard Hat Mack, and then hounded your parents for an Atari or a C64 because the Apple sucked (comparatively) as a gaming computer. Of all my friends who got a computer in elementary school, only one ended up with an Apple after playing on our school’s unit (we went to his house to play Masquerade, which I loved).

    Before Atari, Apple or Commodore, our high school had a teletype that dialed into a DECsystem-10. That's where I got my first experience in BASIC. Now that was a great training computer :)

    I don't know how to do it in Windows, but I found this website very useful, it explain how to write the image to the esp-01 without arduino ide.

    http://subethasoftware.com/2018/02/25/how-to-load-zimodem-firmware-to-an-esp8266-without-arduino-ide/

    DON'T USE THIS ON THE ESP-01 with the ZiModem, that's what messed mine up...

     

    Edit: The ESP-01 needs the BOOT code stored at 0x00000, I don't think the ZiModem bin has that stored there.

    Thoughts on using a Joy Port to support flow control:

     

    While Kyles' idea is a good one, it might not be so good if we peek into the future a bit.

    I can envision these WiFi2SIO devices catching on since they will be cheap to buy and program.

    Games can be / will be made to use these in Multi-Player Modes, more than just Chess and BattleShip :)

    These new games will need the use of both joy sticks to make some truly awesome game competitions...

     

    Right now I play Clash Royale and like these types of games....

    yes but there is no reason not to take it further utilizing whatever we need to make sio flow happen, 00, 01, 10, and 11 from two lines comes 4 states...

    Exactly, that's what I posted 2 days ago. Adding hardware flow control to the R-Verter circuit would be doable with a simple add on circuit.

     

    Ken Siders' schematic also has it with the MAX-232 IC. Just saw that yesterday :)

    Windowed protocols can get dicey with 4 k (fmodem packets etc.) since it can be almost 3 or more tcp packets to deliver, so an error w/retry can be a mess. This is why I go with Y-modem batch mostly. I hope the explanation of picking the protocol to match the transport makes sense....

    I think for a software flow control solution to work (in text mode), we'd need small packets like 8-16 bytes and a status return byte of a CRC of that packet like XModem. Just sending XON / XOFF could get misinterpreted if an ATASCII animation is sent.

     

    Some of these ESP Modules have RTS / CTS exposed that we could use in a hardware flow solution. The R-Verter could accommodate this through the use of VPRCED ($202) and the Motor-Control lines. All through the SIO Port only just needing an additional transistor circuit.

    The Motor-Control line would be dual purpose in this application.

    geezer your board has other pins exposed on the reset side of pin rows that might allow for hardware flow control possibly to exist or be added, can you float that idea around in some of it's hobby support experimentation sites and see if a hack and firmware exists already or could be created?

    Flow control is of no concern to me at the moment. These setups work just fine connecting to BBS's online and other TCP Servers I've tried... Nix it...

    I bought 2 of these ESP8266 CP2102 NodeMcu Development Boards yesterday from a local seller in CA to try..

    post-26874-0-34985800-1536967289_thumb.jpg

     

    The NodeMcu flash program loads the ZiModem firmware at address 0x00000 which doesn't work on the ESP-01 boards the same way.

    I've updated the Arduino IDE to 1.6.13 and installed the Esp8266 Board Types to try another way of compiling / flashing the ZiModem firmware. We'll see how this goes after I get them early next week :)

    The 810's like to have the head aligned every now and then. Loosen up the hex nut around the stepper motor (you should be able to move the head slightly while keeping the hex nut still using an allen wrench). Put in a formatted floppy with dos and turn on your A8 (allen wrench removed). You can put slight pressure on the head with your finger pushing it toward you. If it reads continuing track, then just tighten up that hex nut where it is.. If not, you might have to move the head a bit more...

    It is MUCH simpler to do simple text output on the resulting serial data, than it is to render a PLATO display. Take a look at this if you want to understand the processing involved:

    It might be above your head, though.

    Thomas, you are the biggest complainer on this board and your comments are not liked by many.

    If you think you are smart, then frick'n fix your code yourself dumba$$... :P

    And by your responses, some growing up couldn't hurt either ;) 'nuff said...

    I have been BUSTING MY ARSE delivering more than 12 simultaneous targets from the same codebase.

     

    It is being done good enough to be improved when it can be.

     

    If you can do better, then do so. If you can contribute a better I/O handler to the code, then please, do so. Othersise.

     

     

    -Thom

    Still waiting for you to disassemble RVerter yourself with your own labels without line numbers :-D
