Well what can I say other than I got very creative today and whipped out this little jewel, designed to be installed internally. There's a Newer Design Available at: https://ataribits.weebly.com/sdrive.html Board Top Board Bottom The board design is meant to fit directly above the SIO jack, with the only caveat being the need to cut a small slot in the A8's plastic case above the SIO jack to access the Micro-SD slot EDIT: If you want to be able to fully insert and extract the uSD card it'll require a bit more access to the card and likely require a bigger slot to be cut in the case, and/or an extended grip attached to the end of the uSD card. Also thinking it would be great if someone created a 3D printable tunnel.

The Schematic... SDrive-Simple_schema.pdf Here's the Micro-SD Breakout board I chose to go with on this project. AdaFruit P/N: 254 For those that wish to go with OSH Park on the PCB manufacture, here's a link to the shared project: https://oshpark.com/shared_projects/39XO8i67 You'll get 3 boards with Free International Shipping for $19 Boards coming out of the first sample run were successful in operation, therefore the gerbers and firmware downloads provided on this page are good to go. Sorry, but no BOM. However it's a pretty simple project - just use the schematic to determine what's needed. Capacitors should have 0.2" (5.08mm) lead spacing. The resistor is a standard 1/4 watt 5% or better tolerance. And the diode is a Schottky in a DO35 case style (2 possible part numbers are provided in the schematic). Headers are 0.1" (2.54mm) male pin headers, with one already included when ordering the AdaFruit 254. The one for the SIO connections is purely optional, since the wires could be directly soldered to the pads instead. Oh yeah, the 16 Mhz crystal should be spec'ed as 20pf (Jameco Part no.: 325139). This idea was born out of the discussion in this topic.

First post on here. I've assembled 2 SDrive Maxs, and powered them externally and via the SIO port at times. The SIO port power at Atari startup is inconsistent. This is I think what causes graphical glitches that go away once you click on something. The GOOD part of the SIO 5v power is it comes on when the machine comes on (also one less wire). Overall I would just prefer the power to be external, but I still want the SDrive to come on when the machine boots up. My idea is to use an arduino nano to manage the powerup by detecting the SIO 5v, and then allowing power to the SDrive only when the SIO 5v is active. I can't believe you have read this far thank you. Since the SIO 5v is inconsistent at Atari startup, I have the nano wait before attempting to power on the SDrive. All of this actually worked. Except it didn't because the SDrive gets enough power for the display, but not enough for the Card Reader to work. Current power supply is 5.0v 4A (Actually measures around 5.15 to 5.20 volts) Hooked up directly it works perfectly, nice bright screen, SDcard works, everything fine, I just don't want to have to unplug it every time. Could I just install a switch, yes! Unfortunately this method occurred to me while looking for a small switch in my stuff and i want it to work. My next steps are to -try a power supply with higher voltage -try reading the voltage off the transistor more carefully -try power supply with higher amps? -hope one of you all has a great solution for this

I've been working on a small project - after building an SdriveMax. I've wanted to make it smaller and internalize it. Have it working now. Pros: A little cheaper - no screen, no SIO plug Internal - less stuff to lug around Smaller - uses a smaller Arduino with the same chip (Arduino Nano) Powered off constant 5v rail of the main power switch, power controlled using the channel selector switch Built in the 7407 circuit so should play nice on the SIO bus Cons: Setup is hard - SDrive Max relies on screen calibration - I had to burn the EEPROM from a working SDrive Max using AVRdude over ICSP Future directions: See if kbr will release a headless firmware that doesn't stop waiting for initial screen calibration Make an all in one board that uses surface mount and doesn't require an Arduino Nano and a separate TF card breakout Questions?

Atari 8-bit newbie; trying to use SDrive-MAX
echristopherson posted a topic in Atari 8-Bit Computers
I recently bought a plain Atari 800. I just cobbled together an SDrive-MAX and got it working powered by the USB connector, but when I connect the SIO +5V line and remove the USB power supply it doesn't work right. It sort of turns on, but the screen doesn't always show the whole display (sometimes there are thin horizontal "scanlines" over parts of the screen)* and disk functionality seems to be missing. It doesn't finish drawing its UI until after the Atari has gone into BASIC or Memo Pad. Going by posts like this one here (http://atariage.com/forums/topic/212003-what-good-is-an-850/?do=findComment&comment=2748745), which say that the 850 allows the SDrive-MAX to boot up completely before the A800 is turned on due to the 850's dedicated power supply, I decided to reconnect the SIO +5V line and run it through the 850. *(I may be misremembering whether the "scanline" appearance still persists in the newest SDrive-MAX I've built, when it's being powered only from the 800 with no intervening 850; it's possible only my earlier attempt which was really broken had that problem.) However, the result seems to be mostly the same; the SDrive isn't powered on at all until I turn on the 800, and when it does sort of power up, the Atari doesn't seem to be able to boot from it. When I go this route, the screen starts out with the "scanlines" but those eventually get replaced by the actual contents of the screen; but by the time I have the normal UI screen displayed, the 800 is already in BASIC. There doesn't seem to be enough time for the SDrive to finish initializing before the Atari tries to boot. Will BigBen's mod (http://atariage.com/forums/topic/286669-sdrive-max-and-atari-850/?do=findComment&comment=4189162) allow me to power the SDrive from the 850 and 800 alone? More SDrive-MAX questions: Is it dangerous to wire the SIO +5V line to the Arduino and have it also plugged into a USB power supply? I would assume so. Is there an editable (e.g. STEP or IGES) file for Kbr's XL-style case? I've printed it from STL twice, using somewhat different 3D printer settings, but both times the bottom plate is too long to fit into the top without trimming; that and the pegs that go up through the Arduino are just barely tall enough to be flush with the board; I'd rather have them stick up a little bit above it. Also, backing up a bit, I'd like to know what's the story with the Option, Select, Start, and System Reset keys as pertains to booting programs and restarting the computer. I've been looking around on Google and in these forums (and in the 800 Owner's Guide) and haven't found much. Specifically, I'm wondering if the advice to hold one or more of those keys while turning the computer on, or hold one or more of them while hitting System Reset, pertains to all 8-bits or just to XLs and XEs (for instance, I know that holding Option allows you to bypass BASIC on XLs and XEs, since their BASIC is built in and not on a cartridge). I've tried various combinations of them while trying to boot the SDrive-MAX and haven't found any of them to do anything noticeable. Thanks. -
I would like to make a SIO2SD - SDrive comparison. INSTALLATION: both are easy to install, you only have to put a loader/create a folder on the SD card; then you just copy all your .xex and .atr from your PC without compatibility problems. PROGRAMS SELECTION: both offer on screen selection, SIO2SD let you select programs from the lcd display too (useful to swap disks or create them on the fly). ON SCREEN MENU: SIO2SD displays long filenames of all files, SDrive displays long filenames of selected file only. http://youtu.be/QGtoUvxmJxY NUMBER OF DRIVES/DISKS SUPPORTED: SIO2SD 15 - SDrive 4 (f.e. Alternate Reality, The Dark Crystal, F.R.E.E., Gunslinger need more than 4 disks) SPEED: according to this thread, SIO2SD seems faster but IMO more tests need to be done. SD CARDs: SIO2SD up to 32GB - SDrive up to 2GB LAST SOFTWARE UPDATE: SIO2SD 2012 - SDrive 2009 PRICE: SIO2SD parts are more expensive but SIO2SD devices strangely seem cheaper. EDIT: recently AtariAge user santosp started selling cheap SDrives (look my topic for newbies). VARIOUS CASES: SIO2SD SDrive CONCLUSIONS: SIO2SD and SDrive are both good devices. SIO2SD has the advantage of drives/disks supported (15 instead of 4, important for some games contained in more than 4 disk), disks selection/creation on the fly thanks to lcd display and loader long files names display (all files, not selected ones only). Please feel free to fill voids, add fields and correct me if I am wrong. I will update this post accordingly.

SOLD I have a brand new SDrive micro I bought last year (2012) for sale. I tested it to make sure it works (it does) and that's it. I also have a SIO2SD that is good enough for my needs, so this one can go. Has the case and the SIO cable attached. Don't wait for another run, get yours now! I think this was right around USD$75 last year. I can get a better pic if you want, but it looks just like any other SDrive micro Make offers via PM. Thanks.

Hello all, I am having an issue using one of my SDRIVE's with my Stock 130xe (IDE Plus 2.0 Not connected during initial test). A little background, I have 2 Sdrives, 1)SDRIVE Nuxx from the latest run , 2)SDRIVE from Morethangames,atari8maestro.com. 1) I have tried three different 2gb SD cards, 1)PNY, 2)Kingston and 3)Sandisk 2) Used the SDRIVE.ATR with the newest date I could find from 2011, with all 3 SD cards 3) With SDRIVE MTG in 130xe loads very fast on all 3 sd cards, no real issues. 4) with SDRIVE NUXX in 130xe loads very slow, about one load beep per second, there is a buzzing from the speaker in between beeps. the buzzing is not like a noise or feedback, its just like the buzz when the atari boots into basic just before the ready prompt appears. 5) I tried 2 different SIO cable with same results. 6) I dug out one of my 800xl and using same power supply as i did with 130xe, same SIO cables, Sdrive nuxx runs normally may actually be faster then the SDRIVE MTG on the 130xe, SDRIVE MTG also run very fast on this 800xl. One other thing I did notice, I was using my SDRIVE to load the files needed to configure my IDE Plus 2.0 on 130xe, 7) Sdrive NUXX when connected to 130xe with IDE Plus 2.0, IDEtoCF adapter and Rtime8 cart. SDRIVE NUXX, barely works. I get the same buzzing sound listed above but the load beeps are about 3-4 seconds apart. Sdrive MTG with same configuration listed on line 7, works fast, no issues. 9) I did not try the Either SDRIVE with IDE Plus 2.0 connected to the 800xl. So, I was wondering if anyone has had a similar issue, or maybe an idea of what might be the issue with the SDRIVE NUXX on my 130xe? On a another note IDE Plus 2.0 is crazy fast!! Gotta Love that!! Best Regards Robert Miller
