side expansion port
    IBM XT emulation
  • 8088 @ 4.77 MHz
  • optional 8087 FPU
  • sixteen DIP sockets for up to 512 kB RAM - 256 kB is preinstalled in eight of the sockets
  • supports 256k×1 150 ns or faster DIPs, in 128, 256, 512 kB configurations
  • RAM can be expanded up to 640 kB using a RAM expansion card in an XT slot
  • 128 kB dual port RAM visible by both the Amiga and PC (8 kB for mono display, 32 kB for colour display, 16 kB used for maintenance of records, 64 kB for data exchange, 8 kB used for I/O registers)
  • connects to the side expansion port
  • covers the mouse and game ports, they are passed through to the front of the Sidecar
  • requires the A1000 to be expanded to 512 kB (ie. by the A1050 expansion cartridge)
  • turning on power to the Sidecar unless the Amiga is powered up can seriously damage the Amiga - use the attached power-cord extender so the A1000 is powered through the Sidecar, though this means the A1060 has to be turned on all the time even if it is unused
  • two display modes
    • monochrome: instead of green text on black screen, the Sidecar can display four colours in PC monochrome mode - the colour of text, intensified text and the background are independent of each other and freely adjustable
    • colour: text can be rendered in up to 16 colours, and graphics can be up to 4 colours
    • neither modes support blinking of text
  • can use the Amiga parallel port - it has to be dedicated to either the Amiga or the PC side exclusively
  • printing works only for applications using interrupt handshaking - those writen with busy-wait loops will not work (eg. Print Screen)
  • three XT ISA slots
  • optional 1 MB memory expansion for the Amiga side
  • 360 kB 5.25" floppy drive built in - up to four floppy drives are supported

  • support for custom EPROMs, static RAM, and SIMM modules for any methods of storing computer OS

    • AppleTalk is fully supported via two optional 8 pin mini-DIN serial ports, (230400 bps normally, 921600 bps between two Emplants via AppleTalk, 460800 bps when connected to a Doubletalk board) - Appletalk printer / network support
    • optional autobooting SCSI controller (NCR 53C80) - pseudo DMA transfers up to 1.1 MB/s (not necessary if the Amiga has SCSI already)
    • serial and SCSI can be used on the Amiga side independently or simultaneously
    • optional hardware (Sybil - two passthrough connectors: one plugs into RGB, other into parallel) to handle 800 kB Mac floppy disks
    • Sybil operates by changing the clock speed of the Amiga's custom chips to match the different data rates of Mac formatted disks (the video display gets very distorted because of this)

    • Atari STE compatible ROM socket
  • Medusa v2:
    • Atari ST / TT emulation
    • two Atari ROM sockets
    • works with 68030 and 68020 + MMU processor cards (68010 or 68020 without MMU does not work)
    • uses the 32 bit RAM (copies the TOS into Fast RAM for speed increase)
    • with 8372A Agnus, 60 Hz display is possible
