  1. Sure, but first I need this: 3d-Printed Book-Scanning Frame for Smartphones Is there anyone willing to help with pdf editing as I'm only going to create a bunch of pictures?
  2. Hi all. I'm in possession of this, will try to do a scan also when I have some time.
  3. Recently just got back to Atari after 30+?? years break, yes I know it's been awhile. Anyways I got this (UHD 4K Composite S-Video RCA AV to HDMI Converter Upscaler 1080P HDTV AV Adapter) for my 4k monitor ( LG Electronics 42.5" Screen LED-lit Monitor (43UD79-B) and it does seem to work properly on Atari 130 XE NTSC system. Granted I haven't checked yet the lag or if there is any. Overall the screen looks excellent.
  4. PAL, NTSC, or SECAM to 4K HDMI auto detection.
  5. Atari 130XE, no issues here with LG Electronics 42.5" Screen LED-lit Monitor (43UD79-B) and UHD 4K Composite S-Video RCA AV to HDMI Converter Upscaler 1080P HDTV AV Adapter Converts and upscale Analog Composite Video & S-Video (from DVD / VCR / STB / Game Console / Camera etc.) to digital Full HD 1080p & UHD 4K Video (Suitable for use on today's HDTV, HD Monitor & HD Projector).
  6. As someone who is in the middle of designing my own SIO2SD Atari 8bit Disk Drive emulator based on Teensy 3.5 MCU I was able to dig some information about the K Boot loader. // The KBoot loader was written by Ken Siders ([email protected]) // RIP.

Data Sectors // Boot Sectors // Sectors 1 to 3 contain necessary information to boot the disk and load the executable file located at sector 4 and above. // The function of the first 13 bytes of sector one is indicated in the table, the remaining bytes of sector one, // as well as sectors two and three contain the code to load the file. // // Byte Offset Function // 0 Unused. Usually 0. // 1 Number of sectors to initially boot. This is set to three // which is enough to get the loader into memory // 2 to 3 Boot Load Address. 1792 ($700) // 4 to 5 Initialization Address. Called after booting requested number of sectors. // 6 to 8 JMP to Boot Continuation Address. This is a 6502 jump // instruction (76/$4C) followed by the address to jump to after // booting the requested number of sectors. This routine will then // load the actual file which is located at sectors 4 and above // 9 to 11 Number of bytes to load (number of bytes in original // executable) This is a three byte value. The least significant byte is stored first. // 12 Unused. Set to 0 // // Data Sectors // Each sector holds a full 128 bytes of // data — there is no sector link information stored in a sector. The // file contains all of the bytes verbatim from the original file // including the $FF $FF header, multiple load segments, initialization, // and run addresses. The file should be processed exactly as it // would be by Dos. The last sector may only be partially filled // and may be padded with random data. The length to load is // determined from sector 1 (the KBoot), bytes 9 to 11. Extracting the // original file is easy. If processing from an ATR file read and // verify the 16 byte ATR header. Read the first three sectors // (384 bytes). Get the length from bytes 9 to 11. Read that // many bytes from the KBoot file and write to the output file. // Done. byte KBOOT_LOADER[] = { 0x00, 0x03, 0x00, 0x07, 0x14, 0x07, 0x4c, 0x14, 0x07, 0xAA, 0xBB, 0xCC, 0x00, 0xa9, 0x46, 0x8d, 0xc6, 0x02, 0xd0, 0xfe, 0xa0, 0x00, 0xa9, 0x6b, 0x91, 0x58, 0x20, 0xd9, 0x07, 0xb0, 0xee, 0x20, 0xc4, 0x07, 0xad, 0x7a, 0x08, 0x0d, 0x76, 0x08, 0xd0, 0xe3, 0xa5, 0x80, 0x8d, 0xe0, 0x02, 0xa5, 0x81, 0x8d, 0xe1, 0x02, 0xa9, 0x00, 0x8d, 0xe2, 0x02, 0x8d, 0xe3, 0x02, 0x20, 0xeb, 0x07, 0xb0, 0xcc, 0xa0, 0x00, 0x91, 0x80, 0xa5, 0x80, 0xc5, 0x82, 0xd0, 0x06, 0xa5, 0x81, 0xc5, 0x83, 0xf0, 0x08, 0xe6, 0x80, 0xd0, 0x02, 0xe6, 0x81, 0xd0, 0xe3, 0xad, 0x76, 0x08, 0xd0, 0xaf, 0xad, 0xe2, 0x02, 0x8d, 0x70, 0x07, 0x0d, 0xe3, 0x02, 0xf0, 0x0e, 0xad, 0xe3, 0x02, 0x8d, 0x71, 0x07, 0x20, 0xff, 0xff, 0xad, 0x7a, 0x08, 0xd0, 0x13, 0xa9, 0x00, 0x8d, 0xe2, 0x02, 0x8d, 0xe3, 0x02, 0x20, 0xae, 0x07, 0xad, 0x7a, 0x08, 0xd0, 0x03, 0x4c, 0x3c, 0x07, 0xa9, 0x00, 0x85, 0x80, 0x85, 0x81, 0x85, 0x82, 0x85, 0x83, 0xad, 0xe0, 0x02, 0x85, 0x0a, 0x85, 0x0c, 0xad, 0xe1, 0x02, 0x85, 0x0b, 0x85, 0x0d, 0xa9, 0x01, 0x85, 0x09, 0xa9, 0x00, 0x8d, 0x44, 0x02, 0x6c, 0xe0, 0x02, 0x20, 0xeb, 0x07, 0x85, 0x80, 0x20, 0xeb, 0x07, 0x85, 0x81, 0xa5, 0x80, 0xc9, 0xff, 0xd0, 0x10, 0xa5, 0x81, 0xc9, 0xff, 0xd0, 0x0a, 0x20, 0xeb, 0x07, 0x85, 0x80, 0x20, 0xeb, 0x07, 0x85, 0x81, 0x20, 0xeb, 0x07, 0x85, 0x82, 0x20, 0xeb, 0x07, 0x85, 0x83, 0x60, 0x20, 0xeb, 0x07, 0xc9, 0xff, 0xd0, 0x09, 0x20, 0xeb, 0x07, 0xc9, 0xff, 0xd0, 0x02, 0x18, 0x60, 0x38, 0x60, 0xad, 0x09, 0x07, 0x0d, 0x0a, 0x07, 0x0d, 0x0b, 0x07, 0xf0, 0x79, 0xac, 0x79, 0x08, 0x10, 0x50, 0xee, 0x77, 0x08, 0xd0, 0x03, 0xee, 0x78, 0x08, 0xa9, 0x31, 0x8d, 0x00, 0x03, 0xa9, 0x01, 0x8d, 0x01, 0x03, 0xa9, 0x52, 0x8d, 0x02, 0x03, 0xa9, 0x40, 0x8d, 0x03, 0x03, 0xa9, 0x80, 0x8d, 0x04, 0x03, 0xa9, 0x08, 0x8d, 0x05, 0x03, 0xa9, 0x1f, 0x8d, 0x06, 0x03, 0xa9, 0x80, 0x8d, 0x08, 0x03, 0xa9, 0x00, 0x8d, 0x09, 0x03, 0xad, 0x77, 0x08, 0x8d, 0x0a, 0x03, 0xad, 0x78, 0x08, 0x8d, 0x0b, 0x03, 0x20, 0x59, 0xe4, 0xad, 0x03, 0x03, 0xc9, 0x02, 0xb0, 0x22, 0xa0, 0x00, 0x8c, 0x79, 0x08, 0xb9, 0x80, 0x08, 0xaa, 0xad, 0x09, 0x07, 0xd0, 0x0b, 0xad, 0x0a, 0x07, 0xd0, 0x03, 0xce, 0x0b, 0x07, 0xce, 0x0a, 0x07, 0xce, 0x09, 0x07, 0xee, 0x79, 0x08, 0x8a, 0x18, 0x60, 0xa0, 0x01, 0x8c, 0x76, 0x08, 0x38, 0x60, 0xa0, 0x01, 0x8c, 0x7a, 0x08, 0x38, 0x60, 0x00, 0x03, 0x00, 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
