Atari hardware hacks and mods


Personal homepage about small hardware developpments around the vintage ATARI ST STE TT range of computers using Xilinx and Altera CPLDs, FPGAs.
MEGA STE
MSTEIDEM 16MB ALT-RAM + IDE + 512KB TOS
  • 512KB flash ROM allowing dual-TOS or cartridge operation.
  • ATA-IDE interface suitable for silent Compact flash cards as well as conventionnal harddisks.
  • memory upgrade (Alternate Fast-Ram at 8 and 16MHz) up to 11Mb on top of ST-RAM
 MEGA ST
MSTIDEM 16MB ALT-RAM + IDE + 512KB TOS
  • 512KB flash ROM allowing dual-TOS or cartridge operation.
  • ATA-IDE interface suitable for silent Compact flash cards as well as conventionnal harddisks, including 2.5" and 3.5" connectors and a 2.5" hard disk place holder.
  • memory upgrade (Alternate Fast-Ram at 8MHz) up to 16-4-1 = 11Mb on top of ST-RAM
  • USB-slave UART

 TT 030
TTRAMIDE: IDE + TT-RAM for ATARI TT
  • Xilinx XC95XX CPLD  acting as memory and IDE control unit.
  • EDO RAM controller with two slots supporting  following 72-pins 5V SIMM modules:
EDO 2*4MB, 2*8MB, 2*16MB or 2*32MB
EPM up to 2*64MB
  • ATA-IDE interface with up to two devices, HDDRIVER and ATARI compatible

 ST/STE/MEGA STE/MEGA ST
STDMAPLUS: IDE + ETHERNET on DMA PORT
  • Xilinx SPARTAN 3 FPGA  bridging the ST DMA port to two IDE buses and an ETHERNET controller (DAVICOM 9000E)
  • ATA-IDE interface with two IDE buses in DMA mode allowing up to three devices.
     IDE0 features a compact flash adapter
     IDE1 features 40-pins IDE header with up to two devices
  • DAVICOM 9000E ETHERNET adapter for a 10Mbits/s TCP/IP link in DMA mod
STBOX (ST in a box) or STMINI
Long term project having no priority with following features
  • Xilinx SPARTAN 3 FPGA  emulating all the original ST chips but the 68000
  • 16MHz 3.3V 68000 processor
  • ATA-IDE interface in fast PIO or DMA mode
  • SD MMC card for TOS or any OS boot as well as game disk images
  • 2* PS/2 connectors for mouse and keyboard
  • 16MB SDRAM RAM memory
  • 2 DB-9  joystick ports
  • VGA output 16-bits colors
  • DMA sound 44.1kHz stereo
