There was talk of a lower cost version with less features. Is this the full blower version that allow all the bells and whistles (SID emulation, covox, Quad Pokey, etc) or this version just a version with stereo Pokey with covox?

Hi @ScreamingAtTheRadio, Thank you! So does this means the hardware portion has been worked out? Which version of the Pokeymax 4 is this?

You should be able to use a bodge wire to fix the trace.

My 130XE was working fine, but when I realized it had MT, I decided to do some proactive maintenance. The 130XE boards can be fragile, but with some patience and a steady hand, the RAM can be replaced.

Hi @reifsnyderb, It is funny that you mention this. There is a GitHub page to create a new delay line circuit board. It has schematics posted and I thought you may be interested in taking a look: https://github.com/redhawk668/Atari-CO60472-Delay-Line-Replacement/tree/main/Rev. C

Were the GTIA chips made by the same manufacturer or different manufacturers?

On a more positive note, @reifsnyderb, you received a very nice article about posted about your remake project! Congrats! I happened upon it from a post on the Atari 8 bit subreddit. Here is the link to the article: https://www.hackster.io/news/brian-reifsnyder-designs-an-advanced-remake-of-atari-s-800xl-mainboard-95cbc0823bb3

Hi @reifsnyderb, This is great! When it is finalized, I may be interested in a couple of adapters when they are ready. One question: did you do a test fit with a keyboard to see if your adapter is low enough? The 800XL keyboards slope very low towards the front. In my experience the Alps keyboards allow the most clearance. The more common models with a plate allow for less space (and some of us may spring for a fancy new keyboard that may have even less clearance😄) When I had ordered the Byte Attic’s Sally adapter, I ordered the PCB a little thinner (I believe 1MM vs the standard 1.6). I also still opted for sockets for the adapter. I had ordered low profile 40 pin sockets for the adapter and for my remake motherboard.

Hi @ijor, I hope you are well! I am checking in to see if there any new updates on this project. I am still very interested in getting one.

By the way, @mexiace, How is your soldering skills? On most 130XE’s, the chips are soldered to the motherboard. You would need to desolder the GTIA chip and install a chip socket to install the Sophia

Joystick ports. The 5200’s are analog. I am not sure how the 5200 joystick ports are wired to the Pokey vs how it is on the Atari 8bit.

@Matt300ZXT, If you get either the AVG or Subcart, make sure to get the cable to connect to the SIO port. This way, you should not have issues playing disk based games.

Just pledged for a case 2 pack! Thank you!!

Here is post that shows what @Havok69 is talking about. It is a DVI to VGA combined with a VGA to SCART adapter. https://forums.atariage.com/topic/349584-wtb-original-sophia-rgbcomponent-video-upgrade-not-sophia-2/#comment-5229160 As @Mitch stated, if your Sony display supports Svideo, you can give that a shot. It may not be as sharp as RGB, but it would still look great without going through the expense and effort of setting up for RGB.

My vote would be for a Sophia 2.
