G-Force 030 (Impact A2000-030 Combo Series II) SCSI Controller Card with 13MB RAM for Amiga 2000

Description:
Great Valley Products (GVP) G-Force 030 (Impact A2000-030 Combo Series II) with 13MB RAM for the Amiga 2000

The card works perfectly with Kickstart 1.3 (WB 1.3) and Kickstart 3.2 (OS 3.2), providing stable and fast performance across both classic and modern Amiga setups.

Configuration:

• GVP G-Force 030 accelerator (1MB onboard RAM)
• 12MB RAM installed (3×64-pin SIMMs, 4MB each)
• Quantum 4GB SCSI hard drive (mounted)
• Hard drive bracket
• Ribbon cable
• Manual
• Original hard drive install disk

Technical & Additional Details:

• It is in perfect condition with no damage
• The card has not been repaired or modified
• Card has been carefully prepared and secured for safe operation
• Components are double-secured with tape and rubber supports to prevent mechanical stress or damage
• Upgraded and tested at 33 MHz, running reliably above standard specifications
• Features dual socket configuration allowing independent clock setup for CPU and co-processor
• Based on technical data, stable operation is typically up to 40 MHz
• Equipped with an external switch to disable the 68030 accelerator, allowing compatibility with software requiring stock configuration
• Includes a Quantum SCSI drive, one of the largest commonly used and well-matched drives for this controller

Performance:

• Very efficient and stable under both Kickstart 1.3 and 3.2
• Supports Kickstart ROM mapping, significantly improving Workbench performance and system responsiveness

Condition:
Fully working system, clean and well-maintained.

Complete set.

Regards and have fun!

processor
• 68EC030 @ 25 / 40 MHz or 68030 @ 50 MHz, PGA
• 68882 @ 25 / 40 / 50 MHz, PGA - clocked at the same speed as the 68030

memory
• 25 MHz: 1 MB on board + three SIMM sockets gives 13 MB max
• 40 / 50 MHz: 4 MB on board + three SIMM sockets gives 16 MB max
• supports only special 64 pin 1 or 4 MB 60 ns GVP SIMMs
• maximum 8 MB is autoconfigured in the 16 MB address space, the exact amount is set by jumper
• the remaining memory is configured as extended memory by the FaaastROM driver

Impact Series II SCSI controller
• 1.2 MB/s transfer speed
• direct DMA transfer to onboard Fast RAM
• FaaastROM SCSI driver (gvpscsi.device) - auto booting requires at least Kickstart 1.3
• DB25 external connector
• 50 pin internal header
• supported by Linux and NetBSD
• optional hard disk mounting kit allows installing any 1" drive on the back of the card

notes
• 32 bit expansion bus for the EGS 110/24 graphics board
• if the EGS 110/24 is installed no place remains for the hard disk mounting kit
• 68000 fallback mode switchable either by software or jumper
• in 68000 fallback mode RAM and SCSI is also switched off
• Kickstart remapping
