Hi everyone I’m back and my project too.
It was not easy. Not because of the technical issues, just bad karma.
In 2011/2012 I made a working firmware and a manager under Max/MSP.
Because of personal reasons, I put the project on hold.
End of 2012, I received a message from Eptheca who asked me the status of the project.
With his help we decided to print 3 PCB’s. Unfortunately during this period, the hard drive of my computer suddenly decided to leave me, and I lost all my work: ((
Features:
PIC 18F4685. Leds Meter for each channel. In Circuit programming (bootloader). Jumper for select PortA Pin0-7 or PortA Pin4-7 + PortB0-3 on DB15 connector. (Future extension ex: old Joystick). Midi I/O with leds. Two Audio output with jumper selection, depends on TIA chip.
Firmware is working.
Manager is ready.
Features:
2 dedicated envelopes with optional non-linear curve for each voice, which can be assigned to Pitch and Volume 2 additional envelopes with optional non-linear curve which can be assigned to Pitch and Volume 4 additional LFOs with different waveforms which can be assigned to Pitch and Volume Pitch Bender Portamento with optional "Constant Time Glide" function Delays Arpeggiator Poly, Mono, Multi and Legato Mode Separate keyboard zones
The Television Interface Adaptor(TIA) is the custom chip that is the heart of the Atari 2600
game console, generating the screen display, sound effects, and reading input controller.
I/O Pin:
Clock and CPU Synchronization:
The 3.58 MHz oscillator (OSC Pin) also clocks a divide by three counter on this chip whose output (1.19 Mhz) is buffered to drive an output pin called 00.
This pin provides the input phase zero clock to the microprocessor which then produces the system 02 clock (1.1
I'm probably a bit nostalgic for a time I played the game console in the living room of my parent.
Need electronic sounds that have traumatized my childhood.
The Atari 2600.
I started this project 5 years ago. The first prototype I built was too big and too expensive to manufacture and not programmed into MIOS:
A friend of mine recently reminded me that I had promised to make one for him(another nostalgic).
So I resumed work in late 2010, after checking that no one already did.
