Amiga Processor Peripherals


Warp Engine

> Company: MacroSystem, US
Date: 1994
Amiga: 3000, 4000
Interface: CPU slot
Autoconfig ID: 2203/19

Processor
68040 @ 28 / 33 / 40 MHz: the board was available with an empty CPU socket to put an existing 25 MHz 68040 into it the 28 MHz 68040 is an overclocked 25 MHz one

Memory
A4000: four 72 pin SIMM sockets accepts up to 128 MB RAM
A3000: two 72 pin SIMM sockets accept up to 64 MB RAM
supports 4, 8, 16, 32 MB, 60-80 ns SIMMs: 40 MHz version needs 60 ns SIMMs, 33 MHZ needs 70 ns, 28 MHz needs 80 ns
full 040 burst memory access (4/2/2/2 clock cycles – 64 MB/s memory bandwidth)
configuration: wait-state jumpers for slow SIMMs, jumpers for setting the size of the biggest SIMM, jumpers for double-sided SIMMs

Fast SCSI 2 controller
NCR 53C710 @ 40 MHz
32 bit SCSI host bus DMA interface supporting burst to/from RAM
max 10 MB/s synchronous transfer speed
autoboot ROM (warpdrive.device) – can be disabled by a jumper
incompatible with the A3000’s motherboard SCSI controller – replacing the A3000’s SCSI chip to rev. 08 solves the problem
external SCSI connector is only available separately
supported by Linux, NetBSD and OpenBSD

Notes
cannot maprom
MMU and cache disable jumpers

Amiga 3000 Notes
not expected to work with static column RAM on the motherboard
can provide 25 MHz clock signal to the motherboard (useful for a 16 MHz A3000 system)
