FastLane Z3 SCSI-2 Controller by Ian A.Clark
The Z3 FastLane is a Zorro III Fast SCSI-II DMA controller for the A3000 or A4000 with transfer rates of approximately 7MB/sec Asynchronous and 10MB/sec synchronous operation. It will support devices with SCSI, SCSI-2 and Fast SCSI-2 interfaces. It also has provision for up to 64MB memory (256MB as an option) in the form of standard 30-pin SIMM modules. RAM speeds supported are 60, 80 or 100ns. It is compatible with Buster revisions -09, -10 or -11.
For fitting inside the A4000/040 with version 3.0 68040 processor boards, a 74FCT240 clock driver chip is also provided. This replaces the original 74FCT244 chip at position U103 on the motherboard, directly under the processor daughter-board.
For fitting inside the A3000, the Buster revision level MUST be -09 or higher.
Software is also provided, on a single floppy, in the form of Workbench and CLI utilities for configuration and control of SCSI devices, a CDROM filesystem and a memory cache utility.
(Editor's note: a Usenet post by David A. Newman states that board revision 2.4 is the most current, with 2.3 and 2.2 also available. Revision 2.2 boards under serial number 31001650 may require a patch by Phase 5 Germany to work with a Broadcaster Elite or DBC32. Use with a 68060 may require a new ROM from Phase 5.)
MultiFace and FastLane Problems: When using both the MultiFace III and FastLane boards in the A4000, the FastLane should be in a lower slot, closer to the motherboard. If the MultiFace board is lower than the FastLane, using the MultiFace software's PIT0: device will cause the machine to lock up.
