I am pleased to inform you that MIDIcar was appreciated at the ABBUC competition in the second category. Thank you very much to all voters!

Full description, schematics and software will be available in first thread of this topic.

Welcome on the Board Matej,

I see many tasks for you according to your mechanical/3D/electronics skills

Hi Matej, Nice to hear that anyone in willing to use it :-) Unfortunately you should wait for a moment because Abbuc HW competition. When it will finished ( a couple of weeks ), a few devices will be available on PTODT market. If you are willing to build it by your own hand, the MIDIcar project will...

Introduction I would like to present new device for Atari XE series which can play/record MIDI files on Atari 8-bit computer. Idea was taken from Mytek's SIO2MIDI (https://ataribits.weebly.com/midi.html) but I decided to use CART/ECI port for communication with MIDI devices because in case I may us...

For your own production you may use collected and sometimes created by me KiCAD's library with all known sockets and expansion ports...

viatronics-logo.png Introduction Inspiration for this mode was nightly discussion with some friends and their request to make device which will be capable to connect ant EPSON/IBM printer to Atari. We had MicroPrint on the market in the past but nowadays it’s rather not possible to find it and use ...

Hi, This is my first post on this subforum. I've EnverBridge EVB202 as devices which communicate between micro-inverters and envertecportal.com to collect data... but i don't like send anything to china cloud so I'm looking for other possibility to read data from PLCC... I disassembled EVB202 lookin...

Hi, As you mentioned, the /RESET line is open drain and for normal work you need to pull-up it to Vcc thru resistor but I suppose your microcomputer system has this line pulled-up in other place. Are you sure that PCF8584 RESET pulls the line down? It's input pin, so probably PCF is damaged. I had i...

I analysed my project again according to additional information regarding specific timing (AN96040 - added to first post) and now I'm pretty sure that the interrupt signal may disturb data communication between PCF8584 and microcomputer subsystem. I'll cut /INT line from existing PCB (especially tha...

Hi, Generally it's look very good... (KiCAD)? Actually I see one issue... please clarify if I'm wrong. You are using the same CLK signal for 6502 and PCF? If yes, PCF will not be capable for so quick operations at all. Nice address decoder but in case you have many shadow registers :-). Did you conn...
