Fastlane Z3 RAM Configuration
RAM Speed Configuration
Depending on the speed of the slowest SIMM used the Fastlane Z3 Controller needs to be configured accordingly. Always choose a setting identical to or slower than the speed of the slowest SIMM used.
Attention:
To avoid causing damage to the Fastlane Z3 always enable one, but never enable more than one of the four speed selector jumpers.
Fastlane Z3 RAM Banks
As the Amiga uses a 32bit data bus, 4 modules of same size must be fitted into one bank. The allocation of the SIMM sockets to the 4 available banks is shown in the following picture.
The jumper setting tables are based on the total bank size, where each bank is composed by four SIMMS the following way:

Fastlane Z3 SCSI Configuration
LED Connector (LED)
This connector provides the possibility to connect a SCSI bus activity LED.
Termination Power (TP) (closed)
If that jumper is closed the SCSI module provides termination power to the SCSI bus.
Jumper 4: Synchron Auto-Enable (closed)
If this jumper is enabled FASTLANE Z3 will analyse information entered in the RDB (Rigid Disk Block) for the SCSI devices connected (especially hard disks or removable disks) to check whether the disk drives should operate in synchronous-mode. It will then automatically activate the synchronous transmission mode. If this jumper is not enabled any synchron-entries will be ignored and the hard disks will operate in standard asynchronous mode.
Jumper 3: Slow Cable Mode (open)
This jumper should only be enabled if transmission problems occur when using extremely long cables, especially for the connection of external SCSI devices (normally only for cable longer than 5M).
Jumper 2: Slow Inquiry Mode (open)
This jumper should be enabled if hard disks are only recognised once the computer has been reset and not immediately after the computer has been switched on (which mostly happens with older models). This is because the hard disk start-up time is too long. The Slow Inquiry Jumper lengthens the time which FASTLANE will wait for the response of the hard disk.
Jumper 1: RESERVED (open)
Jumper 0: Debug Mode (open)
Only for test purposes by authorised service personnel.
