  1. But if I do RGB mod is this still an issue?
  2. You're right.. which would be the worst of both worlds!! The best of both would be PAL60. If I understand this correctly, the system sets colors/encoding (PAL vs NTSC) The ANTIC sets the frequency (50 vs 60hz) So for best compatibility, you'd want a PAL60 which means NTSC ANTIC in a PAL system. Sure, some things will still not work correctly, but it sounds like there is no "solution" that will work with every game and every demo, at correct speed, and full size screen.
  3. Interesting. So if I install the Sofia RGB mod. And the PAL ANTIC I should get video color back on the PVM and have Pseudo PAL / PAL60?? without changing the GTIA?
  4. I just found an XEGS PAL picture online. Oh my. The PAL system has 2 crystal and resistors around it (ntsc has 1 resistor that connects the empty space to the existing crystal) And as far as chips are concerned. Yes. GTIA differs as well. hmmmm So. a better question then is. Is it worth converting a system (XL or XE) to PAL vs NTSC for games?
  5. In order to increase game compatibility, I've converted older consoles from NTSC to PAL with great success. This is especially true for the C64 and Amiga line of computers. My next retro computer of choice is the Atari XE .. in particular, I've purchased an Atari XE GS. I then installed a 40 pin socket where the ANTIC goes, and replaced the C021697-31 (NTSC) with a C021698-07 (PAL) which I purchased from Best Electronics. I have a PVM that can show PAL/NTSC as well as XRGB mini. - When I turn the system on, before any modifications, I get Missile Command (XRGB reports 240p NTSC). - When I swap ANTIC to PAL version, I still see Missile Command - but in Black and White on the composite out port! (XRGB reports 288p PAL) So my questions are: 1) Is swapping ANTIC the only required procedure for XEGS? Or am I missing something (like crystal on C64 and Amiga) 2) Why would the picture be black and white on PAL and color on NTSC ANTIC? Composite out from C64/Amiga in PAL mode show perfectly fine on my display devices. I know they can handle it. 3) Am I doing the right thing by converting to PAL? I recently purchased an AVG cart and my goal is to play as many Atari 8 bit games as possible on it.
  6. Small update to AVGcart cost - it seems to have gone up to 50EUR from 40EUR
  7. I got 2 Mega ST 4 units but no keyboards. Let me know if you got one for sale.
  8. would the TF328 work in an NTSC console? if so, how does one convert the video output to PAL using this device? Is there an option to automatically convert to PAL mode on bootup?
  9. Happy 2018 McWill!!! Now where is that Nomad LCD screen you were working on back in 2016?

  11. instead of using hot glue, use 2 part epoxy. JB weld makes a special version for plastic. love it!
  12. really? For me the screen had to be pushed all the way down, till it hit the cart slot. The default display had it vertically aligned but shifted to the left. 2 modes later (stretch horizontally) filled the screen perfectly.
  13. yes. It's normal. As McWill explained to me: in GG mode it has 7 modes: 1. Scaled H+V 2. Scaled H+V scanlines 3. Native H (doubled resolution) + scaled V 4. Native H (doubled resolution) + scaled V scanlines 5. Native H+V (doubled resolution); upper and lower picture cut off! 6. Native H+V (doubled resolution) scanlines; upper and lower picture cut off! 7. Native H+V hold A + B + start and one of the modes will horizontally stretched to fill the whole screen.
  14. did you remember to connect the sms wire?
  15. Did another McWill GG install today. This time I got unlucky, a 1 chip! (lots more components to remove and soldering than 2 chip). But that's OK, did it all under my scope and works great. couple fo suggestions: R24 replaced by R30? That resistor is a penny. Why not ship it with the kit and mark it as such (not to confuse with other resistor). Some people will use wide solder tip to heat both pads of resistor and flick it off. This process kills resistors. I prefer to put new resistor than reuse. Vcc and GND instructions not clear. Especially for those not using the wheel to control backlight/have VGA out. I ended up finding 5V and GND on port that goes to the power pcb. Closest hence least issues. Apart from that, instructions are much better than I remember. And as always, breathtaking when first turned on. Marco. I want my NOMAD screen!!
