Processor: 020 (16Mhz version @ 14.32Mhz)
FPU: 68881 (Optional 68882 can be installed at up to 50Mhz)
This accelerator plugs into the 68000 socket so can be used in any Amiga which has a 68000 providing there is enough clearance for the board. This card is known to work in an A2000 (Please Note: Conflicts with A2091 SCSI Card), A500 and should work in an A1000 with a socket extender. The CPU is tied to 14Mhz and can not be changed. The FPU requires an additional crystal for it's clock speed, and is automatically detected. If you use a DMA controller such as an A590, A570, A2091, GVP Series II etc, then you may have to turn off the memory autoconfig function of the accelerator. This is done via jumpers (explained below) Additionally the DMA (direct memory access) mask must be modified with the software belonging to the fixed disk. The mask is modified by FFFFFF on 4FFFFF. Memory over 4MB must be removed. Possibly all ram on the controller must be removed and switched off. Failing this, there is probably a timing problem which cannot be fixed.
Jumper Settings
"1/4MB" - Closed = 1MB ram. Open = 4MB ram.
"Cache" - Closed = 68020 CPU cache disasbled. Open = 68020 CPU cache enabled.
"68000" or "68K" - Closed = Turboboard uses 68000 CPU, 68020 CPU off. Open = Turbobard uses 68020 CPU.
"Autoconfig" - Closed = Memory will autoconfig. Open = Memory will not autoconfig, use AddMem to add it. Address is from $200000 to $2FFFFF (if 1Mb) or from $200000 to $5FFFFF (if 4Mb).
"CIA" - Normally OPEN. If the Amiga crashes, e.g when clicking on icons etc, then Close it.
