    I decided to build a new set of paddle controllers to use with my FB9 Gold HD. I used the 10K single turn Bourns potentiometers mentioned in post 35. I mounted them in 2 1/2 inch diameter x 2 inch high wood boxes I bought at www.acmoore.com for $1 each. I completed the paddles with N.O. push buttons and sacrificed 1 Atari Keyboard controller for the connector/cable. The Keyboard controller is one of the few devices that has all 9 pins connected. The second paddle controller is wired to the first using 4 wire phone cable. I used knobs purchased from Radio Shack years ago. The paddles work well - my Breakout score is improving. The knob has to be rotated nearly stop to stop to play the game. This is different from the original Atari paddles on a Atari 8 bit computer - where only about 1/2 a turn is required.

    As was recently discussed on this form, an ATX power supply requires a minimum load to operate correctly. I'm not sure the Atari draws enough current to operate with an ATX power supply. A 2-3 Amp 5V DC power supply designed for a Raspberry Pi should work better. You'll just need to splice in a DIN plug. These power supplies are widely available for $9-$14.

    If you want this project to be successful, you should also consider the cost of the hardware. Mytek's SIO2MIDI board is very inexpensive. I paid $50.22 for all the parts to build 3 assemblies. This includes the cost of the custom printed circuit boards and all shipping/handling and taxes. You would need to add the cost of 1/2 SIO cable and a MIDI cables per assembly. A 10 foot midi cable is $2.69 from Monoprice.com

    The PIA project seems like a big project - both hardware and software. A simpler approach is MIDI - now that Mytek has released the SIO2MIDI board. The 2 port board can be built for $15 each (and $6 of that is for the 5 pin DIN jacks). MidiMaze supports up to 16 computers - so MIDI seems up to the task. k-Pack has MIDI information at http://atariage.com/forums/blog/572/entry-13705-a8-midi-and-the-atari-age-of-rediscovery/

    My plan is to leave SIO pin 10 (5V) unconnected, and power the SDrive Max from the 5V provided by the USB connector. So I will be powering the chip from the 5V from USB also. Any issues?

    I can easily run 2600 games under Stella with just a SNES gamepad under RetroPie, but not having much luck running Atari 8-bit computer games using the same gamepad. I would need to map the Option (F2), Select (f3), Start (F4), Cold Reset (Shift F5) and Exit Emulator (F9) to gamepad buttons. This would allow me to run Atari 8-bit games without a keyboard. There are enough unused buttons on the gamepad for these functions. Any ideas?

    ClassicGMR, I've never seen a single USB arcade button. Typically you'll need to buy the arcade button (microswitch) and then interface it to USB. I'm not sure if pboland has button inputs on his trackball. If not, you can use a 32U4 based Arduino for the interface. Buttons and interfaces are available from https://www.adafruit.com/

    skr, Great job! I'm on level 63. How many levels are in the game?

    Pixel is the Desktop environment on Raspberry. It's not installed by default in RetroPie, but you can add it according to https://github.com/RetroPie/RetroPie-Setup/wiki/FAQ#where-did-the-desktop-go

    I see files up to 16K in size, and my Atari Flashback can play them all. I recommend you rename the files as suggested
  11. Forrest
    You are other thinking such a simple process. Just copy the games from your Windows machine to a USB thumbdrive formatted for FAT32. Eject the thumbdrive from your Windows machine. Launch the Desktop on your Raspberry (type startx). Insert the thumbdrive in your Raspberry. Open the thumbdrive with Filemanager and drag the files to the proper folder on your Raspberry. Eject the thumbdrive (eject icon in upper right corner). Quit the desktop back to the command line. Type emulationstation and run your new games.

    Your link is for a USB to an EL panel inverter. EL panels have unique power requirements - high voltage and very low current. In a circuit, an EL panel acts as a capacitor. My point is this inverter is not suitable for powering anything but an EL panel. FYI they sell EL inverters that can be powered from a 9V battery.

    Was it common to have socketed ROMs in production cartridges?

    Thanks for posting this information. I just finished building the SIO2MIDI interface (2 port version) released by Mytek at https://ataribits.weebly.com/midi.html and discussed at http://atariage.com/forums/topic/269207-midi-interface/ I installed mine in a wood box - see posts 441 and 442.

    I attended on Sunday and was very impressed by all the people I met and all of the hardware on display. It was great meeting Bill, Curt, DanBoris, Thom, ClausB and others. Curt's collection of Atari's prototypes that was on display was amazing. There were prototypes like the STPad, large version of the TT030 computer and the 1090 Expansion box that I had never heard about before. I thanked Curt for the Atari USB joysticks he sold a few years back - did not know Curt built 16000 joysticks by himself! My 4 joysticks are still working. Joe Decuir's keynote was very interesting. I never knew Atari briefly sold computers with defective 16K memory boards as 8K machines! I'm looking forward to seeing Joe's keynote video and the additional interview he did at Curt's display.

    7thSun, You will need to edit the filenames to remove spaces. This was mentioned in page 1 of this thread. I've used a batch renaming program to remove the spaces from the game pack in the Atari portable thread, and all the games I've tried work fine.

    I'm thinking of using an ESP8266-12E device with a MAX3232 level shifter for a WiFi modem for the ST. Amazon sells the HiLetgo New Version ESP8266 NodeMCU LUA CP2102 ESP-12E for $8.39 and I already have the MAX3232 chip. The ESP8266-12E only cost $1.25 more than the ESP8266-01 (lacking the CP2102 USB to serial converter). I figure the CP2102 will be helpful in flashing the firmware with my Windows machine. The Zimodem software on https://github.com/bozimmerman/Zimodem looks useful. Anyone use Zimodem with their Atari ST or use this setup?

    I finished building my first SIO2MIDI board and have it assembled in a small wood box - looks pretty good. The wood box measures 3.5 x 3.5 x 1.75 inches high, and purchased for $1 at acmoore.com. The board was easy to build. I used a PICKit 3 clone to program the chip. I found out MPLAB defaults to low voltage programming when selecting the PIC12F1572. This is incorrect for this application - you should select high voltage programming in the Advanced tab of MPLAB. I used an SIO jack from salvaged from a 1030 modem. I soldered DuPont wires to the SIO header on the board

    The top status line on the bottom of the screen is: # lives remaining (heart icon), # fruit needed to complete level (cherry icon), level (eject icon).

    I've spent about an hour playing Fruity Pete. Great game - I'm up to level 51.

    I used the version of Stella that's automatically installed when RetroPie 4.4 is installed.

    I've played many 2600 games thru RetroPi with a Raspberry Pi Zero W - no problems at all. Atari 800 games also run, but you really need a keyboard attached.
  24. Forrest
    I have setup a few Raspberry Pi's using RetroPi and think this is a better alternative. A new Raspberry 3B+ will cost you $70-$100, after you add the case, power supply, SD card and a USB Game controller. The system is fast enough to run a web browser, so you can download files from the internet. A Raspberry 2 or later (4 core CPU) will all work fine. 2600 and NES emulation will work on a Raspberry Pi Zero or Zero W, but web browsing is very slow because of the single core CPU and limited memory.

    I installed Wine and WineBottler directly about a year ago under El Capitan and haven't used it again until last night. I'm currently running High Sierra. Wine documentation says it currently runs 32-bit Windows apps.
