  1. 😄 Hehe this way i hack the game back in the day (lot of money).
  2. In Post #6 you show 3 pictures with some capacitors, all of these capacitors point to TL497A IC#107 at least in Atari STe Schematic (Rev A, C300780-001). The TL497A switching voltage regulator operate in numerous voltage-conversion applications (step-up, step-down, invert) with as much as 85% of the source power delivered to the load. I wonder if you screw up here somehow (lose connection maybe, bad soldering job ) perhaps you ripped the trace while you were trying to desolder the old caps? Just ignore the first picture I'm having difficulties with Windows 10 and few beers 😄
  3. Ohh if you do get this going get the Wemos D1 Mini Arduino Development Board ESP8285 for the next hack if you want the perfect picture quality and GBS 8200 board. 😉 https://shmups.system11.org/viewtopic.php?f=6&t=52172 good luck reading this it took me two days 😄 GitHub link: https://github.com/ramapcsx2/gbs-control
  4. When you mentioned the Arcade VGA converter I had a hunch, welcome to the family. 😁 On Atari STFM (TV Frequency Modulatior) models you can probably just modify the cable (disconnect pin #9 and connect to pin #2) but for Atari ST and STE you need the video sync mixer. NOTE: this is untested as I don't have any Atari STfm. About the esynic VGA to HDMI converter, 15khz and HDMI will never work I can tell you this much.
  5. Well in my case I had no luck with GBS 8200 VGA Arcade Converter until I build video sync mixer for Atari 1040 STE (H sync+V sync to (C sync))
  6. Used for Notator SL: https://www.youtube.com/watch?v=LK1pIpWrDC8
  7. Thanks for the heads up I really need one for my Falcon 030, it hasn't been ON since 1995-97? 😟
  8. Currently On My Wishlist: OSSC Open Source Scan Converter 1.6 with SCART Component VGA to HDMI for Retro Gaming - Kaico Edition Sounds Too Good To Be True.
  9. I actually did on Teensy 3.5 its in very early alpha stage and currently trying to figure out a easy way of connecting micro sd card to Teensy 4.0 MCU, and yes I am doing this with frequency shift keying (FSK) decoding in software loading the sectors in 64k buffer. It's more or less proof-of-concept for now perhaps I should upload video on my YouTube channel?
  10. Thanks for the offer my design is based on Teensy 3.5 ARM Microcontroller, here from March 27 2019: SIO Atari Drive testing. I'm experimenting with lots of things right now for example: WAV file FSK (Frequency-shift keying) ATARI Cassette tape decoding with sound support (8bit or 16bit mono or stereo channel), not sure when I will release the source files but it will definitely be under MIT license.
  11. Interesting discussion, I've been working on my own SIO Drive implementation because of the binary releases only ?
  12. Sure, but first I need this: 3d-Printed Book-Scanning Frame for Smartphones Is there anyone willing to help with pdf editing as I'm only going to create a bunch of pictures?
  13. Hi all. I'm in possession of this, will try to do a scan also when I have some time.
  14. Recently just got back to Atari after 30+?? years break, yes I know it's been awhile. Anyways I got this (UHD 4K Composite S-Video RCA AV to HDMI Converter Upscaler 1080P HDTV AV Adapter) for my 4k monitor ( LG Electronics 42.5" Screen LED-lit Monitor (43UD79-B) and it does seem to work properly on Atari 130 XE NTSC system. Granted I haven't checked yet the lag or if there is any. Overall the screen looks excellent.
  15. PAL, NTSC, or SECAM to 4K HDMI auto detection.
