810 Drive has been sold! 2/13/22

First let me say yes this is my first posting HERE in this group to offer up items for sale, however I have been selling on Facebook Marketplace and Mercari for Years so happy to share my 5 star reviews so you can buy in confidence. I have the following for sale and will provide pics. ALL Have been tested and are cleaned inside and out and have been serviced, any issues are described below: Atari 800 Computer - I have a cleaned and tested (Inside and out) Atari 800 Computer , this is one that was made in Sunnyvale California, Not Taiwan. It is complete in box and works (Loads games from disk and plays cartridges) however the keyboard which is the highly desirable Mitsumi does not work. I have taken this whole computer apart to clean inside and out, including keyboard. The issue is a simple one to fix but will require disassembly. I just do not have the time to fix what needs to be fixed, but I do know that is the issue. It also has 48K ram installed. Comes with Basic Cartridge and power adapter. $300 + Shipping Atari 1010 Disk Drive - I have a Atari 1050 Disk Drive - Cleaned Tested Works! It comes with original power supply and some mysterious switch on the side. I will throw in some disks with games on them as well for your gaming pleasure. $125 + Shipping Indus GT for Atari Computers - I have a Indus GT for Atari Disk Drive, Cleaned and Tested Works!

The Clear pop out door has an issue on the right hand side as you can see from the pic but still will open. $200 + Shipping SOLD!! 2/13/22. ** Atari 810 Disk Drive with issues - Atari 810 Disk Drive - Cleaned Tested (Has issues), I opened this one up to clean the head and lubricate the rails. It also has two mysterious mechanisms inside which look to be a speed switch and something else. Does not boot disks properly and will need repair which is why it is being sold at this price. Also includes power supply. $30 + Shipping Competition Pro Joystick - Competition Pro Joystick for Atari 5200. Cleaned and tested. Very uncommon! $75 + Shipping SOLD!! 2/14/22 Atari 800XL Motherboard - Bad Ram otherwise I believe it works fine, shows black screen. Ram gets hot when plugged in. Insert other media

So for those whom are not super great at soldering or finding another solution I had the same issue as I replaced my complete motherboard with a new one from Best Electronics. When pulling it out the clear plastic header was coming away from the pins. So I took a trimmed piece of double sided clear tape and applied it to the header, I then flattened out the pins with a needle nosed vice grip so they were flat and adhering to the adhesive and with some careful re-insertion whalla the keyboard works as it should. Will it be a lasting repair? Not sure but it fit into the pin header and got everything to remain flat.

Ok but it should still work with FF or Rewind which those are not working either but I will hook it to a computer this evening when I am down in the workshop.

Will do. I have been going through the disks in my spare time.

SO an update after a weekend marathon of some additional cleaning and testing: Atari 800 has a Mitsumi Keyboard so I would need to repaint the contacts on the mylar - Going to sell "As-Is" as it does boot games but you cannot use the keyboard but still complete in box. Atari 810 Drives, down to 1 that is having a boot error, I did end up greasing (with White lithium) and one works where as it did not before. Everything else works as it should. I am keeping one Atari 800, One 1050 and one 810 Drive and a 1010 Tape which I must have done an oopsie on, as it was sort of working when I first took it apart to replace the play button but when plugging it back in seemingly I get the red power light but nothing is moving on the mechanism when I press a button. Ill continue to sort through the disks looking for anything that could be of value to the community

OK so with some additional testing with a single sided disk I have both 1050 drives working, the in box 810 working the Indus gt working but the two loose 810s are still throwing a boot error like maybe every 10 secs

Thanks will do, my goal is to fix the second one since it is complete in box and sell it as such. Appreciate all the feedback!!

Also This Atari 810 Drive has several holes drilled in the side with the markings in the picture. I am guessing something to do with speed adjustment as I read that these drives did not have a speed control built in? Also this dial controller looks foreign as well?

Thanks for the tips I have a lot of reading here to do but will be putting things through their paces again this weekend armed with this new knowledge. I will report back of course.

So here is the switch mod in the 1050 Disk Drive. Looks like the brown connector was not connected not sure if it should be and that green circuit board does not belong on that black capacitor I am guessing. Any idea what I have here?

OK thanks I am learning and appreciate all the information.

So thats interesting. Since the Commodore 64 had basic built in all games are essentially basic games (Assume aside from cartridges)? So then most games on Atari SHOULD or should not be basic games? Like the common ones, i.e Dig Dug, Buck Rogers, The Eidelon etc. Sorry just questioning that now too.

Yes sorry I meant Disk Drive (should have been clearer). And I am guessing I do not need to have basic cart in 800 then to run games from disk. So just turning on the Atari 800 with a disk drive on and operational as well as the correct density disk for the drive type should "theoretically" boot properly? Since its Friday I will have more time this evening and this weekend to tinker and report back.

I do assume that the boot process is the same no matter what 8 bit computer / drive combination I am using i.e. Sorry for these questions I grew up with Commodore and never had Atari computers so trying to learn the ropes. Atari 800 + 810 DD + POwer and Option Key = Autoboot? Atari 800 + 1050 DD + Power and Option Key = Autoboot? Atari 130xe + 810 DD + Power and Option Key = Auto Boot? Atari XEGS + 1050 DD + Power and Option Key = Auto Boot? Atari 800XL + 810 DD + Power and Option Key = Auto Boot? And so on and so forth

Will do, once I get the 130 XE restored i will run a test with that or the 800XL. I also have an XEGS which I know works and can use with the drives. Either way I will document when I get to that next. Thanks for the help ?

Got it thanks for the suggestion. I might just buy a pre-built one of good quality, yes I could do it myself but with all the projects I have sometimes the easier route is a quality one. Any suggestions there?

Thank you will do so. I am not going to toss this one out iuntil I look at it. One project at a time of course as you can see I have a lot right now with all the drives, power supplies etc. I am working on finishing restoring the 130XE but will be tossing the psu because it is an ingot.

Actually i Believe I have the INgot for my 130XE. I will discontinue using it. I will have to buy a new power supply before I use it again.

I do have all the original power supplies for the drives so yes that's the one thing i DID check was having the correct PSU with several Commodore computers I am more than acquainted with faulty power supplies doing harm.

So this is the power supply I have for my 800XL "circled" in blue Ok so its not circled LOL but its the brown rectangular one in the left hand bottom corner with the other power supply on top of it. That is the one that seems to not be working properly or fried the 800XL which I will need to get around to eventually. OTherwise the "ingot" one I suppose came with the original 800? I think I have one with the 800 and if thats the case I will indeed toss.

McLaneinc so the 99% of the disks are copies very few if any are original. But I am happy to catalogue them when I get around to it.

Thanks for all the feedback, I will respond to every individual response in the next couple of days as I get around to them. for now here are the pics of what I picked up BEFORE I started cleaning it all. I plan to keep 1 810 (Boxed), 1 800 Boxed and, the 1050 Boxed and the 1010 (No Box). I have really no space for any of this but hate to sell all of it. I will use it eventually. ?
