QuadTari

Did you find time for testing?

Hi TJ!

 

Not yet - I'll put this on the to-do list. :)  Is the test to see if the physical QuadTari is recognized when it's connected to the R77 front ports, USB ports, both?  To be sure, what version of Stella should I have on the R77 to test with?  6.5?

 

Thanks!

John

Both if you can. Use 6.5.1 (not 6.5), because there we made the change.

I'm really curious to see how that pans out. Might have to buy a Retron 77 if it will work...that will be a whole lot easier for demo'ing this thing at shows than having to cart around another CRT.

Hmmm, I'm looking on the Stella 6 on the R77 page and it looks like the latest release is 6.4?  Where can I find 6.5.1?  Apologies if I'm missing something obvious.. ;) 

 

EDIT: Guess it was something obvious; I found a link for it on the official Stella download page.  :dunce:

I just received a second one in the mail the other day. I believe I only paid for one. Pm me to make sure. Instead of paying to have it shipped back I might have a friend that would possibly be interested in buying it...

Thanks for letting me know. Turns out there was a glitch in the order tracking software that I use, and it seems to have double-printed labels for some orders (sigh).  I'll PM you.

I believe mine is scheduled for delivery tomorrow. I got the kit version so I will be putting mine together. I like getting kits like this to assemble as it just feels more 'mine' and personal that way? I know...strange right?

I gave it a test.  Through the front pot, it does seem better in that it does detect the 1st joystick properly now, but unfortunately it doesn't seem to be able to read any joysticks plugged into the additional port (port 3 or port 4). 😕   It performed the same through the USB connector in my tests also; it could just read inputs from the first joystick.

 

However, it may just be because I have no way of mapping those ports because they aren't recognized as inputs with Stella.  Meaning, when I try to map inputs to joysticks P2 and P3, I can't map to the additional joysticks because Stella would need to set DUMPPORTS high to enable the physical joystick connected to port 3 of the QuadTari.  I'm confused actually; I'm not sure how it would work in software, but somehow you would need to map using the 2nd physical joystick connected to QuadTari port 3 to Stella joystick port P2.  (and the same for QT port 4/Stella joystick input configuration for P3).  :ponder:

Totally understand. I figured that some people would really enjoy putting them together, and it saves me time on assembly (and thus saves you a little bit of money) Win-win 🙂

 

If you run into any problems with assembly, don't hesitate to reach out!

Hm, I get your problem. I suppose I need a QuadTari first to sort out the problems.

 

Anyway, thanks for testing.

Yours shipped a couple weeks ago, should hopefully be there soon!

So I decided to recruit some help to speed up assembly and try to get caught up. I'm not sure things are going any faster though....

Got my kit this week and assembled it. Haven't had a chance to try it out yet though.

 

My only suggestion is to include sockets for the ICs (even on the ones you sell assembled). Would only add maybe $1 to the over all cost.  Personally, I like to avoid soldered ICs for a couple reasons. But to each their own. Luckily I had exactly 4 sockets on hand for this.

 

Edit: I lied, one more suggestion. Use proper tapered/tapping screws (preferably philips instead of hex) for holding the PCB inside. Starting those machine thread screws was a PITA.

Yeah, I went back and forth on this one while prototyping. I've got a handful of sockets, I can start distributing them with the kits.

I'm still tweaking what screw to use there. I had some better screws for it, but it turns out that the screw holes were sized differently from the prototype enclosure from the factory, and meant that my original screws were too small. so I had to pivot and get something else quickly.

These are excellent suggestions. I installed sockets on mine as well as apparently I have over 20 of them on hand for some other project in the past. I also had a heck of a time getting those hex screws started to hold down the PCB and was about to get my small tap kit to make that easier but I was able to get them in without having to do so.

Just curious...How long are the cords on this

Just shy of 6 feet.

But can you plug 4 more QuadTaris into a QuadTari for a total of 16 ports?

 

(I kid... I kid)

I've been plotting for awhile to next make an 8-player multitap for the NES.

(although this little project has proven to be more difficult to get right than I expected, so I've learned that I'm not a hardware guy)

Do you mean 4 on each port or 8 in one port?

It would be 4 on each port, but using the same method that the NES 4-player multitaps use. The NES reads controller data serially, so the multitaps just stream 8 more bits of data on the same port.

Oh, you mean to use on the Atari ? Something like this? latch and clock line shared and one data line for each NES controller ?
