    2. Atari 2600

      The Atari 2600 is the system that started it all for Atari, and is by far the most popular classic gaming console. This forum covers all 2600 systems produced by Atari, as well as 2600-compatible consoles produced by third-parties.

    3. Atari 5200

      The Atari 5200 was Atari's second cartridge-based game console. Based on the Atari 8-bit computer line and labeled the "SuperSystem", the 5200 was Atari's answer to growing competition in a market they were losing control over.

    4. Atari 7800

      The Atari 7800 ProSystem is a contemporary of the Nintendo Entertainment System and the Sega Master System. Based on extensive feedback from Atari customers, the 7800 features a streamlined design, backward compatibility with the 2600, a powerful graphics processor, and simplified controllers.

    5. Atari Lynx

      Lynx was Atari's first portable game system, and world's first color handheld. It was designed by Epyx and the engineers who created the Amiga. Ahead of its time, the Lynx sported a backlit color screen, stereo sound (in model 2) and an impressive range of games. Check out our rarity guide or explore many games listed on Atari Gamer.

    6. Atari Jaguar

      Atari's last game console, the Atari Jaguar represented a huge leap in technology from previous offerings. Featuring a 64-bit architecture, the Jaguar had great potential, but its power was difficult to tap. Even then, many great games were released and the Jaguar has an avid fan base today.

    • Do you think you also might be able to, while you are at it, open the GSP firmware in MiniGUI and edit it a small amount to change the buttons and add some libretro cores to its database for us GSP gamers? I could mock up some visual ideas for modifying the GUI.

    • Like the others, I also thought that Atari800 used to emulate this but couldn't find any older builds that did so. I took a look at the Atari800 SIO and sound code and it looks like the existing SIO sound approach would need to be reworked. Fundamentally, the characteristic Atari SIO sound comes from the way that POKEY's serial port interacts with timer 3 and 4, particularly in asynchronous receive mode.   This is a scope of when the Atari is transmitting a command frame over the SIO bus, specifically a type-3 poll. This is the farting you hear after DOS 2 boots or when no bootable devices are connected. CH1 (yellow/TX) is SIO DATA OUT, CH2 (cyan/RX) is SIO DATA IN, CH3 (purple) is audio out.     During a send -- SKCTL=$23 -- timers 3+4 are continuously counting to provide the transmit clock for any bytes that are queued to send. It runs continuously regardless of whether a byte is actually being sent or not. Timers 3+4 are configured for a period of 1/38400th of a sec for 19200 baud and the OS configures channel 4 for square wave output ($A8), so the output tone is 19200Hz. This is inaudible, so the primary component heard is the change when timer 4 starts and stops, and not the tone output itself. This is also why the tone starts a little bit before and some time after the actual command frame bytes, since it depends not on the end of the last byte but when the SIO routine in the OS gets around to reconfiguring the serial port.   Each command sent produces a single "putt" of sound. The farting noise comes from the OS SIO routine retrying the type 3 polling commands 27 times, with a timeout driven by OS timer 1. This is VBI-based with a timeout of 2 vblanks, so the puttering occurs at 30Hz for NTSC and 25Hz for PAL.   During a receive, SKCTL is changed to $13 to enable asynchronous receive mode:     This mode sounds a lot different than transmit because of the way asynchronous receive mode affects timers 3+4. In this mode, POKEY has to synchronize to the device's transmit clock, which is out of phase with POKEY's serial clock. Therefore, in this mode, POKEY holds timers 3+4 in reset while waiting for a start bit, and those timers don't run. At the leading edge of the start bit, timers 3+4 are started, and then count off half-bits in phase with the transmit clock so POKEY can sample in the middle of each bit. Upon sampling the stop bit, timers 3+4 are stopped again to wait for the leading edge of the next start bit.   This process causes timers 3+4 to underflow and fire a pulse to the audio circuit 19 times -- which crucially is odd. This means that the output bit is toggled at the end of each byte, which you can see above in the gaps before and after the ACK byte ($41). The result is that the audio output has a fundamental square wave at half the byte rate of the transmission, with bursts of inaudible 19200Hz on top of it. The fundamental frequency varies based on the device, a bit higher or lower than the nominal 960Hz depending on the device. 810s, for instance, produce a slightly higher pitch than a 1050. Note that the byte rate is not the same as 10 times the bit rate, as devices often have a bit of a gap between the stop and start bits. It also means that the tone doesn't depend on the computer's clocks, which means that it is invariant to NTSC/PAL.   What Atari800's SERIO_SOUND appears to be doing is rendering the 10 bits for each byte at channel 4 volume -- 1 start bit + 8 data bits + 1 stop bit. There is often a component of this in the audio output due to the SIO data leaking into the audio output, but it's faint and not subject to POKEY volumes. It's what you sometimes hear when a loader shuts off the main SIO sound and you hear still hear tinny buzzing during the sector loads that varies a bit in timbre depending on the data bytes being received. That's not the same as the stronger transmit/receive effects above, which are independent of the data bytes being sent and received. As far as I can tell, the sio.c/pokey.c/[mz]pokeysnd.c don't implement timers 3+4 being held for asynchronous receive mode, which is a main requirement for emulating this effect.   Probably the simplest starting point would be to override the connection from timer 4 to audio channel 4 and drive audio channel 4 at 0Hz/960Hz when asynchronous receive mode is enabled, running it only when bytes are being received. It's an approximation but would go pretty far towards something representative. More importantly, it's compatible with cheaper asynchronous audio, so it's easier than the next steps of either properly starting and stopping timers 3+4 during async receive mode or driving audio channel 4 with machine synchronized timing. AFAICT Atari800 isn't set up for the latter anyway because it doesn't actually emulate device transmit timing -- it instead sends bytes at the rate that POKEY is set up to receive them, which is not accurate but works most of the time (though it allows some bogus configurations like receiving at the wrong baud rate). The majority of SIO devices send bytes back-to-back at a consistent pitch, though, so it's not necessary to emulate at that level to attain representative pitch. The nominal pitches for receiving from the 810 and 1050, based on the controller clocks and firmware loops, are 943.4Hz and 910.75Hz.

    • I need help determining a graphic on the schematic. I’m using the schematic diagram here and I found a lifted pcb feed to one of the 74LS156 pins tied all together so I’m checking other pins but can’t determine what the open circle is at pins 1, 14 & 15. Thanks for the help, that pin 14 of U7 goes off and should trace to pin 12 of U12 but I’m uncertain about the open circle and my boards don’t seem to trace to that pin.    
    • The mystery deepens with the companion Space Raider.    
    • Alright, but what if I want to use this in a live performance improv setting? Can I at least mute drum and synth sections and whatnot? Another thing I should note is that I'm probably gonna test this on a RetroN 77. The BW/COL button is in the back in that design and I might need an alt button to play sequences, like the RESET button for instance.
    • Did you get it to work? The bluescsi V2 is it internal? 50pin or external DB25. I am trying to get my external Bluescsi V2 working on my TT and no luck so far.. Term out or in.   James
    • Nice work. Thanks for the update.   The keycap adapters are always going to be the trickiest part to get right - the tolerances are very small. Mine worked well in PLA. I've since tried PETG and have found the retaining bumps on the adapter stem do seem to wear down.   Is the main issue the connection of the adapter to the switches? or the keycaps? It sounds like the switches, but if it is the keycaps, the spacebar-specific adapter might work better. The only difference is the retaining bumps on the stems are 0.1mm larger.   I might try and pick up a few different brands of switches to try as I've only tested the Akko switches linked in the repo.
