So wait, I am confused or did not read the details or pay enough attention... My original UNO R3 (I built some time last year) was the chip on board with micro-USB and I initially used a 1n4148 on TX line which seemed to work OK. Recently tried to power with 12V AC/DC and fried the unit. So I rebuilt using a Inland socketed UNO R3 and still used a 1n4148 on the TX line. While doing all of this I purchased one of the sub-boards (delivered today) to install. Is it NOT required on the socketed UNO R3 boards. It's just required for the chip on board version?

I'm back in action. Picked up new board locally from MicroCenter. It's an Inland branded board on sale for $7.99. There was nothing wrong with the touchscreen. Just the UNO board. Using a 1n4148 inline and 5V USB power. All SIO devices are working. Since this is not a micro USB version like my original build, need to get another case printed or file the slot open...

Hah! Well good to know now... ...I have another uno and screen on order. Should be here by end of week.

The SDrive-MAX Arduino has several options for power. - SIO 5V - USB 5V (w/SIO 5V wire removed) - AC/DC 7V-12V (w/SIO 5V wire removed) I was using the SIO 5V, but noticed low power flickering, so I decided to remove the SIO 5V power wire and use the AC/DC input. That is when things went south...

Not sure, but thinking I fried my UNO board. Last night got the bright idea to use a universal power supply at 12V. SDrive-Max powered up, screen came on then within seconds, the screen went completely white in color. Unplugged it and then chose 9V. SDrive-Max powered up like normal, but I am no longer able to use the touchscreen, except to maximize/minimize the command line window (READY prompt) by touching random areas on the screen. I can't get into [Cfg] or anything. SDive-Max still loads the D0: atr file and I can still operate using my 8-bit onscreen commands, but that's about it. A few months ago, I lost 1TB harddrive with all my files, so I downloaded Arduino IDE 1.8.9 and installed the proper CH340 driver. The COM 3 port is showing as being the active port. I am unable to upload any sketches, etc etc etc. Any thoughts? Fried board? Error message for all attempts is as follows: (BLINK test) Sketch uses 930 bytes (2%) of program storage space.

Thank you.

Fully understand. That's life! Thank you for the ROM. Keep on gaming my friend!

Just picked this up from Michael Thomasson at CORGS-Con 2019 (Hilliard, OH). Only played it for a little bit, but it is a great homebrew! High quality gloss labels and nice instruction sheet included. Is the ROM still available for download? Also, added benefit. I tried this on my Retron77 and it recognized the game. GOOD JOB!!!!!

So there are discrepancies right off the bat with the photos. You can clearly see that it's not the same cartridge in all of the pictures. The label is different and worn in different spots in each photo AND in one photo you can clearly see the label is crooked, yet the other shows it perfectly straight. Shenanigan's for $10k - NO WAY!!!!!!!!!!! Hard for me to believe this is the same cartridge or maybe my eye sight is going bad... https://www.ebay.com/itm/Gamma-Attack-Atari-2600-VCS-1983/283502715430?hash=item4202142226:g:XfsAAOSwBfJcyj33

I think that ad is misleading. The Atari 2600 Space-Age Pro-line looked nothing like that. I have one in my collection still in the box. Here is a picture taken from http://www.ataricompendium.com/game_library/controllers/controllers.html

It's for the 8-bit Atari computers. AtariLab...

Bought one a year or so ago, used, like new in box with all packing and docs off ebay. Works fine. All keys as well. Seems to be hit or miss with these...

Unfortunately, Windows no longer can see it and I tried third party software as well as diskpart (which can see if but says it's unavailable). Imaging software no longer sees it either.

So overwhelmed seeing this beta release. Was so excited to try it out... Long story short, I re-imaged my 128MB microSD that came with my Retron (had the community build on it) and it became unusable. Windows no longer sees the drive either. Apparently, the SD Card took a dump. A huge one. I tried a few different steps and apps to recover it. Pulled out an extra 32GB micro SD and tried same beta image. It successfully wrote image but still not working. Windows DID see it. Not giving up I decided to download the beta image again. Deleted previous download, re-imaged the 32gb micro SD and success. Loaded games and off to the races. Now I have a useless 128MB Hyperkin Retron77 micro SD card to throw away.

Would love to see rally cars rendered. You can make both. Enduro bikes and rally cars. Just a thought. Choices....

Yes there is. I have both units in my possession.

That was me. Came home today to a surprise package. Dropcheck, these things are incredible. So simple yet so effective!!! THANK YOU!! I'll eventually have a 3D printed shell or modify a cartridge shell to protect them.

These came today. Was shocked to see them delivered. Big shout out to Dropcheck for making this happen. These are simple yet quite effective XE/XL 90 degree cartridge extenders. Will eventually have a 3D printed shell or modify a cartridge shell to put them in. I already have an Atari 400 CIB in my collection, but could NOT pass this "B" Keyboard modified unit up. Buy it now! $76.59 shipped. Came in original box, styro foam insert, warranty card, empty RF switch box, and power supply box with wrong PSU inside. Luckily, I had extra power supplies. Everything works on it. Keyboard feels good and is responsive. Finally got to try out my never been played, owned since the 80's Demon Attack cartridge. I had an 800XL as my first 8-bit back then, so it would not work.

Want so bad... ...spare 1050 patiently waiting for a new life... ...praying these things come available to the common folk.

What do we need to do to confirm interest? Would love to get this going as it appears there is more interest then just me.

On the retrobright, is it possible to spray a layer of satin UV clear coat over it? Just a thought to protect from future yellowing.

Me being the simple man with simple requirements. THIS IS EXACTLY what I was looking for. Now, I am not familiar enough with or have the right contacts to have the board made or know which cart connector to purchase even if I had the board in hand. How would I go about getting something like this made available to me? I would end up placing it inside of a 8-bit cart case (either a donor or a 3D printed version). Even though this is nothing more then an extension board, I still feel that it would benefit quite a few individuals who do not need all the extra bells and whistles but get frustrated whenever they want to insert a cartridge. I have all the other 8-bits (except original 800), a few modified XL's etc, and a few XE's, but enjoy using the 130XE for some odd reason. As everyone has stated, I am overwhelmed at how a simple post from me turned into a plethora of knowledge and expansion of my original post. Thanks!

At this rate might try to create a cartridge with 90 degree connector port since no one has released one. just a thought

I recall there being a 90 degree cartridge port extender for the XE models, but have been unsuccessful in finding it. I am aware of the dual switching cartridge port extender, but am just looking for a single port unit. Was there ever one designed?

There is also "The Freezer" by Bob Woolley where you add a hard boot recycle button that safely resets. Do a search... ...I am adding one to my upgraded 600XL when I get time. I have all the necessary parts, just haven't taken the time.
