Atari TT030 Schematic

The twelve-sheet circuit diagram for the Atari TT030 main board, Atari drawing C301762-001 dated 8 August 1990. Sheet 1 carries the power connector J100 with its full pin assignment (PG, +5 V, +12 V, −12 V, −5 V and grounds) and the C100–C105/C120 input network. The remaining sheets cover the 68030 and 68881, the MCU, SCU and TTVIDEO, ST-RAM and TT Fast RAM, the VMEbus slot, SCSI and ACSI, the serial ports and the sound section. This is the primary source for the TT030's motherboard rail and capacitor figures.
