#4114871 SIO Wifi modem with esp8266

Posted by a8isa1 on Sun Sep 16, 2018 5:47 PM

I have a question:


For those who have added RVerter logic to their modules, ESP-1 or nodeMCU/lolin/wemos dev board, have you confirmed that the wifi modem that you created plays nice with real drives?



#4114348 Miner 2049er - Miner Alternative Sprite Edition

Posted by a8isa1 on Sat Sep 15, 2018 7:36 PM

Character now looks like a miner but what do we call him?   Surely not Bounty Bob.


I'm so confused.

I know that both uploads and downloads do work correctly on my board. I recommend 9600,8,N,1 using X-Modem 1K or Y-Modem. This was tested using WIRED Lantronix devices.

If you're having trouble, try a wired device first to see if it works.

I'm now suspecting it the Rverter driver that's limiting me.   The board itself breezes through the ASCII animation at 38.4 when connected to my laptop (running minicom terminal emulator).


Animation runs at higher speeds without scrambling but it does become hurky-jerky.


I don't own any wired devices for connecting to the internet.

I've been running Zimodem firmware (now version 3.4beta).   I had been trying to get the ASCII animation ("star wars") of towel.blinkenlights.nl (telnet) to run via the esp8266 dev board (nodemcu v0.9 clone).  I had assumed my difficulties were that I had been missing some setting or feature of the Zimodem firmware.   I had been BBSing using bobverter driver at 19,200.  I thought successfully.  It didn't occur to me to lower the speed until Yesterday.


9600 improved things greatly but at 4800 the animation runs without getting scrambled (dropped chacters?) until my session times out and disconnects me, at about 1 hr, 40 mins.


I love ICE-T (2.80 alpha 7) even more now!


No, this is nothing productive.  Just one more fun thing to do with the Atari.


Sorry, I don't have a suitable video camera to show this in action.




p.s. to view the video at intended speed just use a modern computer and telnet towel.blinkenlights.nl

#4103438 Bosconian for the 8-bits

Posted by a8isa1 on Sat Sep 1, 2018 9:49 AM

I just checked out one of those "Let's compare" videos and once again we are the lucky bastards having the best conversion :) (Even though it took a little while ;) ;) )

I'm a bit confused though....which versions are there and am I playing the "best" version for my U1MB extended machine ?


Also, are there PAL/NTSC versions ? The version I have now shows a bit graphic errors on the intro screen but plays perfectly using a NTSC ANTIC on a PAL machine.

wow!  I didn't know anyone placed NTSC Antic in a PAL machine.   what's the advantage of doing this?


I live in NTSC land so I don't know.

Thanks but my 800XL is out of adjustment.  I could never get it (along with my scan converter) to line up with any palettes available for Rastaconverter. I had to come up with my own palette.


After I last posted I remembered that my scan converter does reasonably well with PAL images if I shift the hue 3 steps to the left.  

#4082136 Keyboard springs needed

Posted by a8isa1 on Mon Jul 30, 2018 7:22 AM


I have some pieces also. But if Karl has some, it might be cheaper (shipping costs).


Would anybody happen to have a spare Type 5 keyboard spring I could buy? I am also in need of one each of the two types of springs in a Type 4 keyboard. Thanks!

Type 4 springs reminded me of this.  I hope someone reads this and remembers but perhaps no one else would be this dumb.


If you decide to clean the mylar and remove it from the keyboard do no flip the keyboard over!   All the narrow diameter springs fall out!


With a well worn keyboard the spring heights are not all the same.   I never did get that keyboard to look even again and I had lost one spring in the process.

Most convincing water reflections I've yet seen and a top 5 conversion for sure.

Grew tired of trying with this one.  At least the outrigger canoo and the water look good.

By the way, it's true that I'm using palettes with very saturated colors.   I've always tweaked saturation on my Ataris and monitors at least 3 "notches".   I don't have a suitable camera.   I'm doing my best to convey the colors the way I see them on my 800XL using an emulator and customized palettes.

I'm trying to convert a large set of Monet paintings.   First attempts didn't go very well.   This one is OK.  Contrast setting is too high but when I try to lower the setting the colors washout to gray and the overall picture becomes mottled.

I'll keep working at this set.

I got 3 pair of decent quality red/cyan plastic glasses, that fit over my reading glasses (they can also be used without glasses underneath) on Amazon. Less than $6 with free shipping. Of course there is a wide selection from the disposable card-board glasses to high quality ones, for dirt cheap. Below is a few examples, all extremely inexpensive and free shipping. I also use mine for some vintage 3D movies I have on vintage media, and there is a lot of Anaglyph 3D images on line and videos on Youtube. There are some modern movies, like Avatar, that you can get Anaglyph 3D versions of too. 


I sort of feel like I've been there, done that, bought the T-shirt, with subject matter for Rasta Converter, and while trying to come up with a new idea, I remembered Anaglyph 3D and some old card-board glasses I had in a drawer. Of course they were scratched up, so I bought some that would last. But there will be more 3D images to come. These are more difficult than 2D images though...especially the 3D images that are full color, and not just B/W, though even they are difficult. 







About every 10 years or so, from the '80s to the 2000s, some TV station ran a 3D event.  I'd pick up some 3D glasses at a convenience store.   I kept them for anaglyph websites and I noticed anaglyph videos on youtube.   I have only one pair of Red/Cyan glasses remaining.  The Red/Green ones were misplaced or damaged over time.


What I have l left worked with your Rastaconverter generated anaglyph.

A first test in anyglyph 3D Rasta Images. Requires red/cyan 3D glasses.


Star Wars 3D. 60 colors.

This reminds me of something.   I wouldn't be surprised if everyone thinks I'm nuts.   If I stare at the Rastaconverter progress screens at just the right distance (about 1 foot from the screen of my laptop) I can see 3D images just as if I was viewing stereoptic slides.

#4044682 How do I check the Weather on my Atari?

Posted by a8isa1 on Fri Jun 8, 2018 3:05 PM

I guess this falls under silly Atari and linux tricks.




I created a simple telnet server on my Raspberry Pi like this:


socat -s -v TCP-LISTEN:4444,fork exec:"curl wttr.in/Boston?0?n?q" &


"musicbox" is the hostname of my Raspberry Pi.   I'm using the tiny Musicbox distro and never bothered to change the hostname.


"4444" is just an arbitrary port number.


ICE-T's EOL handling is set to "LF only".   I think 8 bit charset is at "IBM PC" though some of the characters used in www.wttr.in's display aren't available on the Atari.
