#4140775 The UAV Rev. D Video Upgrade Thread

Posted by Bryan on Tue Oct 23, 2018 3:42 PM

I want to give everyone an update:

 

I have been working full-time on renovating my house to sell. As many of you know, my wife and I spent 3 1/2 years in Costa Rica and I had a large freelance job lined up that I thought would provide income while we were there. Well, it kinda fizzled due to a lack of interest from the other party and when my wife and I moved back, we were deeply in debt. I bought a cheap fixer-upper house in Michigan so my wife could take care of her mother with advanced diabetes. At first, we were going to live here and slowly work off our debts, but with the rising real estate market combined with a generous offer to live cheaply with friends, it has become important to finish up my repairs and sell the house ASAP for a fresh start. To this end I've been living in a construction zone and maxing out my credit cards to get the work finished and I hope I'm in my final month of this gigantic task (this house was cute, but completely trashed in every way).

 

I'm shipping out current orders as I can make the time, and I hope to resume development of future products as soon as I get my lab set up again somewhere else. I know I still have PMs to answer and I'll fill as many remaining orders as I can, but I'm not planning on ordering any more boards until next year. I just wanted to explain why I dropped out of sight for a little while.

Just found out what happened. Due to budget constraints, Rob Wyatt had to swipe the web server computer when setting up his office.

Likewise, I didn't actually think the shirt was for early VCS backers.

;)

 

Not actually my T-shirt. Pic is shamelessly stolen from the inter-webs.

I see you got the early backer commemorative t-shirt.

 

 

Why are they asking for refunds? They clearly said: NO REFUNDS

Might I suggest an Indiegogo campaign to pay someone to keep the website online?

Why are "written" cells zero instead of one?

I believe it saved an extra transistor per bit cell. With EPROMs, you're basically charging a small floating capacitor acting as the gate of a FET. With no charge present (erased cell), the FET conducts and this is represented by a 1. Once the gate is charged, the FET no longer conducts. UV light can excite the electrons enough that they tunnel through the barrier and discharge the gate (and, they'll discharge themselves naturally over the next 20-50 years).




#4022974 Any Screen Printing Programs for the Atari 1025 Printer?

Posted by Bryan on Mon May 7, 2018 4:20 PM

Yeah, sorry. That was confusing. I was just bringing up why it doesn't do graphics. I had a 1025 back in the day and I was kinda pissed when I realized it had no graphics mode.

From what I've heard, the Okidata equivalent printer was text-only as well. It would be a fun hacking project to put a gfx mode into the firmware. You might need to add a little RAM too.




#4019816 The UAV Rev. D Video Upgrade Thread

Posted by Bryan on Wed May 2, 2018 12:33 PM

Hi everyone.

 

I've been pulled away from my Atari projects for a little bit, so I've ordered a small run of UAV Rev D boards to keep them available until I have more time.

 

The available options are currently:

Basic $22

Plug-In $25

Kit $25

XEL $25

5200 low-profile build $25

 

I'm getting caught up with PMs as well so let me know if I've forgotten anyone.




#4006450 Cassette types (I,II,III,IV)

Posted by Bryan on Thu Apr 12, 2018 1:06 PM

Use a quality Type I. Other formulations will be a mismatch and their main advantages (better response, dynamic range, etc...) don't matter in this application. Tape shouldn't be considered permanent and a digital copy should be made (and saved in a lossless format) as well.

 

Something like the Maxell UR, Sony HF or TDK D range should be fine.

So... your first post is a necrobump of a thread that's been dormant for 8 years?




#3999267 Why were the controller ports on the back?

Posted by Bryan on Mon Apr 2, 2018 2:51 PM

Does rf transmit stereo correctly?

No. The channels are mixed and sent as normal mono audio.

 

Combat uses one TIA channel per tank because, well, that's how you'd probably write the game anyway.




#3999130 Why were the controller ports on the back?

1st of all, consumer video products used RF unless they were expensive devices that needed to be more flexible. VCRs could handle composite because they could be linked together. Video games had RF because everything supported it. Even by the mid '80s, only premium TVs had AV jacks. The NES got people seriously considering TVs with this feature. The 2600 was a cheap legacy product in 1986. It's no surprise they didn't add features that late in the game.

With Kennedy it's easy to predict what he'll put inside.  Either a Snes and/or a DVR capture card.  He must have a trunk load of them in his car.

We need a comprehensive list of all the hardware that's been put in a Jaguar shell so far.
