Operating System

• TOS - The Operating System
• GEM - Graphical Environment Manager
• boot disk
  • to make an autoboot disk put the program in a folder named “AUTO”, when the floppy boots it will skip the GEM environment and go straight from TOS to the executable, this is the default for most games and demos

Common Hardware Atari Hardware

• monitors
  • PS3000: Combined 12-inch color monitor and 360k 3½-inch floppy drive (SF354). Speaker. Manufactured by JVC in limited quantity (≈1000), only a few working models remain.\
  • SM124: Monochrome monitor, 12-inch screen, 640 × 400 pixels, 70 Hz refresh
  • SM125: Monochrome monitor, 12-inch screen, up/down/sideways swivel stand, speaker, 640×400 pixels, 70 Hz refresh
  • SM147: Monochrome monitor, 14-inch screen, no speaker, replacement for SM124
  • SC1224: Color monitor, 12-inch screen, 640 × 200 pixels plus speaker\
  • SC1425: Color monitor, 14-inch screen, One speaker on the left of screen, a jack to plug ear-listeners
  • SC1435: Color monitor, 14-inch screen, stereo speakers, replacement for SC1224 (rebadged Magnavox 1CM135)
  • SM195: Monochrome monitor, 19-inch screen for TT030. 1280 × 960 pixels. 70 Hz refresh
• printers
  • SLM804: Laser printer, connected through ACSI DMA port, used ST's memory and processor to build pages for printing
  • SLM605: Laser printer, connected through ACSI DMA port, smaller than SLM805
• storage
  • Atari SF314 - DSDD, 3.5“ floppy disk drive, 360KB, needs a power brick, you can daisy chain 2 but not 3
  • Atari SF354 - SSDD, 3.5” floppy disk drive, 720KB, needs a power brick, you can daisy chain 2 but not 3
  • SH204: External hard drive, 20 MB MFM drive, “shoe box” case made of metal
  • SH205: External hard drive, Mega ST matching case, 20 MB MFM 3.5-inch (Tandon TM262) or 5.25-inch (Segate ST225) drive with ST506 interface (became later the Megafile 20)
  • Megafile 20, 30, 60: External hard drive, Mega ST matching case, ACSI bus; Megafile 30 and 60 had a 5.25-inch RLL (often a Seagate ST238R 30 MByte or Seagate ST277R 60 MByte drive) with ST506 interface
  • Megafile 44: Removable cartridge drive, ACSI bus, Mega ST matching case

Hardware

• 68000 based CPU, 512 MB,
• to make your life easier, look for the 'newer' models that have the power supply built into the chassis
• 520 Power supply

Hardware

• 68000 based CPU, 1024 MB,

• ACSI2STM
  • a project to add an external SD card via the HDD port
  • uses a STM32F103C8T6 board
  • faster and cheaper than a Satan /UltraSatan
  • it appears to need a high level of TOS, like v1.04 or better (?)
  • you may need a tool like this - 5v CH340G Serial Converter USB 2.0 To TTL 6PIN Module for PRO mini K9
