  1. I did try the INPUT_PULLUP code that you sent me. Unfortunately, it didn't work. However, now I manually hold the pins in the cable, so my transfers are now working well (slowly but surely). After a few hours last night, I managed to transfer 10 (out of over 50) floppy disks.
  2. Hello all 8-bit Atari fans! I have finally managed to allow my Atari (800XL) to communicate with a modern PC, using an Arduino, and three cables (input, output, and ground), and it seems to work just fine, between Atari and PC. Using RespeQt, everything flows smoothly. However, if I throw an Indus GT drive in the mix, things don't work so well. I've tried an SIO chain, but the Indus GT drive goes kind of crazy (doesn't load anything, seems like it writes something...and the head moves around during boot). I have also tried a backup program (Disk Wizard), and reading from the Indus GT drive, and then (at the prompt), disconnecting it, and connecting the wires for the Arduino, and then writing the sectors to a virtual disk...it worked the first time (the first 198 sectors), but for the second try after repeating the process, I got an error saying Bad Checksum (in RespeQt, it gave that error), and then on the TV screen, an error message, and that the backup process had aborted... Is there a way I can overcome that error? Or something else I should (could) try? I would like to back up all of these old floppies, before any more bit rotting occurs... Thank you for any and all help!
  3. Ok, I finally got it to work (turns out, I was supposed to connect to different pins on the arduino). Does anybody know how I could connect the Command Line and have this used in the SIO chain? I'd love to be able to back-up all of my old floppy discs.
  4. I think I am very close to it working. I am using the following code in Arduino: AspeQt gives a "get status" message when I turn the Atari on, but doesn't really get past that. Cannot save (or load) anything. I have the Ground pin connected, and the TX and RX pins connected to their respective slots in the SIO cable.
  5. Thank you for your answer. Unfortunately, the government shut the mail service down a few months ago (and doesn't have plans on reopening it). My brother-in-law has an arduino...any chance I could use that? It uses serial if I'm not mistaken, has a USB interface, and uses 5V (I think). Has anybody had experience using Arduino as a SIO2PC? If so, what would I need to do? EDIT: I don't need SIO2SD, just a simple SIO2USB interface, that will work with RespeQt.
  6. Thank you for your response. I finally had some time (and some jump cables) to try and put this together. Unfortunately, it is not working. Items used: I have tried this two ways: Connecting the USB to Serial adapter to my computer (USB), connecting the board (shown in above image) to serial cable (female and male RS232 9 pin), and then connecting jump cables from GND, TXD, and RXD, to pins 4 (tried 4 and 6), 3, and 5 respectively on the SIO cable (note, I connected the male connectors of the jump cables directly into the SIO cable connector. When I tried this, every time I would get a weird buzz, and then see the Ready prompt on the Atari (800XL). Connecting the USB to Serial adapter to my computer (USB) and then directly connecting the jump cables to the male serial connector, in the respective ground, TXD, and RXD pins, directly to pins 4 (tried 4 and 6), 3, and 5 respectively on the SIO cable. When I tried this, I would get a yellowish/brownish screen, but nothing would display, and there was no sound either. On both tests, I tried with RespeQt. I tried all of the handshakes available (I also tried connecting a jump cable directly from the RI pin in the Serial cable to pin 7 on the SIO cable, and trying that handshake. No luck either. Are there any special settings that I should try to change in Device Manager? I know I am on the correct COM port (4). Any advice? Thank you for any and all help!
  7. Hello again everybody, I tried purchasing one of those USB to serial cables, unfortunately the package didn't arrive on time for somebody to bring it down to Ecuador for me. I purchased a USB to male serial (9 pin RS232) converter...would that be of any use? I also bought this other deal...not sure if either of these devices are useful or not...I do also have a spare SIO cable. Any ideas? A thousand thanks to all for any and all help! Pictures of purchased (hopefully useful) items:
  8. Actually, I do have a couple of old computers with those serial ports, and was hoping I could go directly from the Atari to a serial port, with a serial cable (I thought I could do that, since others went from SIO to serial to USB, I figured I could go from SIO to serial directly). Thank you manterola and TGB for your advice I suppose I can try with a USB to serial cable. Edit: Would this be ok to buy?
  9. Greetings to all Atari fans! I've finally given up on getting a costly cable/converter down to Ecuador, so I'm going to try DIY. Question, could I use a female to female Serial RS232 cable? (same on both ends) Could I cut one end off, and connect the three little wires to the internal pins of the Atari, and connect the other Serial connector to my computer? Is this possible, or would I need some sort of mid-translator/converter? Thank you, James Edit: Cable looks like this:
  10. This solution worked perfectly. I officially feel stupid now. Thank you very much. Should I assume that I need to use semicolon in inputs as well?
  11. STARTSTATE and NUMSTATES are 0 and 126 respectively (that is the number they should be giving, and they are "correctly" printed to the text file, except for the extra spaces). STARTSTATE represents the entry point of the automaton, and NUMSTATES is the number of states in the automaton. INPUTS$ is the list of characters that the automaton accepts. Although the order could be changed (I tried it just in case and got the same result of the spaces), it doesn't (in my theory) affect the outcome. EDIT: To be specific, there are ten spaces at the start of each line.
  12. Good evening all, (Background Information) I am creating a program in BASIC, and sometimes when I write text files to disk, I get a weird "tab" character, comprising of several spaces at the beginning of each line. As evidence of so many spaces, the file size is considerably greater than it should be (is several bytes bigger for each line, and in one file that had hundreds of lines, the file-size was almost five times bigger). EDIT: There are exactly ten spaces at the beginning of each line. My code looks something like this: I have made other BASIC programs that do not do these weird tab characters. Example: This has no "tabs" or spaces at the beginning of each line (like the first photo shows). What am I doing wrong here? Any and all help will be greatly appreciated. Thanks, James
  13. Thank you for the reply, unfortunately I am limited to typing in the Basic code since I have no way to communicate with any modern hardware. I am looking into getting an SIO2PC converter soon.
  14. Thanks to both of you for your suggestions. I cleaned the head with some alcohol and it seems it is now able to read some disks. About the CopyMate, is that a program for copying disks? I have around 30 or so disks, so it would take me quite a while to copy all of them. Thanks, James
  15. Hello all retro Atari users, I haven't used my Atari for around a year now. I hooked everything up yesterday, and the Atari 800XL still works fine. However I am having severe issues with the disk drive. I was able to load one of my homemade Basic programs and some songs that I had composed. However, any further attempts to load any games, Dos, or reload the Basic program have failed. I get g4 and g5 errors on the drive on ANY disc that I am trying to load. I do not know much about drive maintenance (my young age relative to 8-bit computers may be involved). I do not know if I should try cleaning the head or if I need to put some kind of grease in the rails where the head moves. I know that the information on the disks is still intact (for the most part anyway), because I was able to load several things on my floppy disk, and later it would try to load and after a few beeps would give the error "blurp". After repeated attempts, it won't correctly load anything anymore, so that's why I think it's a drive maintenance issue. All help is greatly appreciated. Thanks, James
