Several people have asked me about the possibility of converting RGB to HDMI. There are several solutions available based on the RaspberryPi Pico but they require much greater skills - the subject is quite difficult (for me) and more expensive... Maybe one day I will try to analyze the AN0-AN3 signa...

Wprowadzenie W poprzednich postach pokazałem, jak podłączyć wyjście wideo Atari do scandoublera. Tym razem chciałbym pokazać, jak zastąpić wytwarzający w Atari słabej jakości sygnał wideo blok elektroniki bardzo dobrym rozwiązaniem opartym na UGV (Ultimate Gated Video Board) opracowanym i zademonst...

Introduction The extension shown below is used to generate an image from Atari so that it can be used in Scan Doubler to obtain good image quality via HDMI. The system does not require making additional holes in the Atari case. An additional advantage is stereo audio (also via HDMI). The presented ...

Introduction I would like to present my new VRHI device, which may be using for programming, reading and cooperation with any Atari XL/XE devices. The main reason why I decided to build it was the need to quickly write to any cartridge, because writing to an Atari takes a very long time... The pres...

Hi Guys! Introduction. I would like to show you little different clock for your Atari... it's called Multi Clock Module and based on Si5351A programmable VCXO chip. The idea is to have all required frequencies on one board for all Atari models. How to do it? Si5351A has three independently clock gen...

Hi! Introduction For as long as I can remember, the Atari had a very poor TV image through the RF output as well as through the monitor plug. It's even worse when we want to connect Atari to a newer TV that is only equipped with an HDMI input... Important note The description contains only part of t...

Hi, This tiny and cheap project should be very helpfully if your Atari has problem with so many modification inside and outside... Genesis - PHI0 vs. PHI1 vs. PHI2 vs.... PHI2_BUF 6502 CPU using three clock signals for each operation: - PHI0 - clock input - it's main clock source for CPU - for inter...

Introduction I would like to present new very usable variant of MIDIcar called MIDIcarSDX. The idea is to have MIDIcar ready to use without any external device, so I decided to add cartridge with SpartaDOSX equipped with PeBe's Player on CAR: device. MIDIcarSDX.png MIDIcarSDX.jpg Features By defaul...

Hi! Our colleague @mono in cooperation with @atarifun made new very useful driver for VIAtronics (and JOYSTAR - very funny Centronics port based on Atari's joystick ports). In order to be fully compatible with this driver, easy modification should be made: viatronics-przed.png viatronics-poprawka.pn...

Introduction I would like to announce new simple device for Atari XE series which can be used as base for own fun projects. Idea was similar to Arduino and only our imagination has a limit. Device was designed as two different hardware: 1. DIAGari - full decoded address for $DXXX area, /RD /WR sign...
