In the back of my OS manual, I have some cryptic notes scribbled: With 3&4 Clock 399 baud = 11-high 163-164-165 LOW 53766 53764 2980 2976 circled I am sure I knew what that meant at the time. I sure wish I took better notes. 53766 is the Audio channel 4 frequency and 53764 is channel 3 frequency. So I am guessing maybe I wrote directly to the registers for my driver to at least set up the baud rate. I wrote some basic code to do noting but write to 53773 (serial out but I saw no transitions on the serial port.

My 810 does not seem to be working. It is the only serial device I have. I want to write a program to send data to the serial out to see if it is ny 810 or the serail port on the 800 that is the issue. I wrote a RS232 driver for a custom RS232 interface I designed but that was 30 years ago. And of course the code is on the disk so I can't get to it. Can anyone point me to some sample code for talking to the SIO? I just want to send raw data out. Or can someone remind me, do I want to look at the pokey interface or the CIO interface?

Just dragged my Atari 800 and 810 out of storage fro 30 years. The 800 powers up and I am getting video and sound out, I connected the 810. It powers up and goes through its startup procedure. But is I power up the 800 with no cartridge the disk does not load. If I insert the BASIC XL cart and type DOS the Atari goes right to the memo pad. I disconnected the SIO cable from the drive and tried looking for data and clock out with n\my scope but I see no transitions Data Output: Low and remains low Command: High and stays high Clock Out:: : High and stay high. I did a continuity test of the cable and it looks good. The 810 is not connected. Is there something that needs to be jumpered that tells the computer there is a device on the serial port before it sends data? Edit: I see that data out is open collector. I added a 10k pull up to 5V. Still no data out. . Just remains high. Trying to figure out how to send data out. I did it before,built my own Rs232 interface, but that was 30 years ago.

It is tan.

OK I went to the website and I still have no idea what this product does. Other than it having flash memory and ram that is. For use new again Atari owners, can someone explain what this thing does? For example can I get a file of ROM images somewhere, load them on this thing then play them like a old fashioned single ROM?

Welll I took the advice from a few people on this forum and got the yellow (actually mine was more of a brown ) of my Atari 800. I used the peroxide cream from Sally Beauty. It is actually called Salon Care Cream Developer. I used the 40% version, I gave it two treatments. First was almost all day in the sun. The second on the following day for just a couple of hours. I did not treat the keyboard as I did not want to risk it. All in all, I think it came out pretty well. So the first game I had to fire up after 30+ years was Donkey Kong. The only cartridge game I have. The colors seem awfully dull or dim. Is this normal? My guess it is and it is because of the various tricks used to get multiple players on the screen at the same time. Well I am assuming the game uses player missle.

Nah never made it to the internet., It is still on a tape somehere in my stash.

Well it lists them but does not really say what they do. And here is an example of my peeve with some of these sites. This is what the SIO2PC site says. The Atarimax Universal SIO2PC/ProSystem interface is a redesign of the classic Atari SIO2PC/APE and ProSystem interfaces, combining them into a single multi-function product. OK fine. Well what if I don't know what the SIO2PC/APE is?? The very first one or two lines should tell me exactly what the product does and how it will benefit me. If you want to go on and explain it is a redesign them fantastic. But tell me what it does right up front.

Perhaps it should be a topic for another thread but what the heck happened to Atari? I mean it was way ahead of its time. Reading though the Operating System user manual, I am awe struck by the thought that went into the design of this product. It is amazing the Atari was not selling for a thousand dollars more than it was. While it probably can't compete with the gaming consoles of today, the 400 and 800 platforms are perfectly fine for the hobbyist that wants to develop some simple games and more than adequate for kids to learn the basics of interfacing to systems.

Ultimate Cart, UNo cart, SIO2PC.......I have been away from Atari for way too long. I am even surprised at the number of products I never heard of way back in the day even though I was a loyal subscriber of Compute and Antic. Still have many of the old magazines stored away. Is there one list somewhere that lists all of these ingenious products, gives a brief description and maybe the pros and cons of the product? I little pet peeve on product websites (not necessarily the ones listed) but some sites go on and on on how the product was developed but they don't tell you what the product does! It would be nice to have a list of products and what they do, all in one place that you could refer to.

Aside from a programmable calculator (that I saw mentioned) my very first was the Commodore PET. We had one at the electronics tech school I attend. I sort of jumped ahead in the lesson plan. The PET was for a more advanced class. We were to learn the KIM first which was all machine code. But a classmate had some programming experience already. We asked the school owner if we could use the Commodore after class. He agreed. Once we got to the KIM class (and later the PET segment) my classmate and I were acting as teacher assistants. We very well may have known those computers better than the instructor. Once I started working I bought a PET. My ex cassmate and I were roomies. Later he bought a PET and we would have coding contests. We kept in touch for the longest time trading tips by mail There was no email then My first major game was breakoout for the PET.

I got the actual deoxit since it is so highly recommend. Only place nearby that handle it is Guitar Center.

LOL. My buddy has had a whole garage full of DEC equipment for years. I keep trying to tell him to sell on eBay.

Actually I have one from the 810. I also need to check my huge stock to see if I have a wall wart that would fit the bill.

Thanks for the replay to both here and ebay. So what are the power requirements for the 1050? What voltage and current?

Going to the auto parts store now to get oil for the lawn mower. I will inquire thanks.

I thought I saw the creme peroxide mentioned in the yellowing thread. Where do you get it?

Lowes has something called CRC contact cleaner https://www.lowes.com/pd/CRC-Contact-Cleaner/999964587

Ah I see. There is actually a product called deoxit. Should it be available locally in the US?

Any tips on what to clean the edge connectors with? Best has an alignment disk. Is it worth purchasing? I recall doing that years ago when I serviced IBM PCs but I can't remember the details.

Yep that is it. Sent you a message on connectors via eBay. Can you check please?

Still need to get to hooking up my 810. (so many other things to do ) But I am not holding any hopes that I will get ti working as it was giving me fits years ago when I put it away. As a replacement, what should I look for? I was going to go for the 1050 but is there a certain version I should buy? Is there a good source for these? I found this place http://www.best-electronics-ca.com/8-bit_.htm#SIO2 But they are out of stock. There is also someone on ebay that completely refurbishes them. That looks interesting. I figure if I am going to spend the money, might as well spend a bit more and get a refurbished one. He replaces all of the filter caps and any other parts as needed, does a calibration, the whole deal. Are there clones out there? I checked into 5.25 inch drives thinking I could design my own interface but they are almost expensive as the full Atari drive.

So the original color of the letters is fairly light? All you used was peroxide? What %? Di you expose to UV?

OK thanks. I saw the recolor thing. Didn't realize you used it on the keyboard.

Thanks. Not seeing the part where you got the keyboard shiny (lot of posts in that thread). What did you do?
