Readily available on the Internet, yet hidden by obsolete file formats, the designs of several Atari custom chips (e.g. STE GSTMCU, Blitter) remained seemingly unnoticed. These are the recovered files.

This archive contains:

- The original files.
- The .DWG schematics converted to PDF documents.


An (incomplete) guide to this archive:

* ST ASICs:
ASIC\4051: Multiple ASIC designs (different revisions?) of the ST Blitter
ASIC\4081_COMBO: Multiple versions of the STE GSTMCU. ST4081S.PDF seems to be the latest ASIC design present in the backup.
ASIC\4118_GAME_SHIFTER: "68K Game Shifter" (ASIC design), probably from the Atari Panther prototype

* Non-ST ASICs - not found in the original backup
Contributed by Mike of fpgaarcade.com:
ASIC\4078: ASIC design and schematics. Exact purpose unknown, possibly an ACSI-to-ISA-bus interface
ASIC\4079: ASIC design. Exact purpose unknown
ASIC\4080_UXE_MCU: A lot of information about a design called "UXE", possibly an unreleased Unix Workstation.

PCB: Unsorted schematics (not ASIC designs) for the Atari Sparrow (Falcon prototype) and the Atari Jaguar.
