Manufacturer Great Valley Products, USA | Date 1989 | Amiga A2000 | Interface CPU slot | Autoconfig ID 2017 / 8,9,13 |
- processor
- 68030 @ 16 / 25 / 28 / 33 / 50 MHz, PGA
- optional 68882 @ 16 - 50 MHz, PGA - can be clocked at different speed than the CPU
- optional memory daughterboards
- 68030-RAM8:
- eight 30 pin SIMM sockets accept 4 or 8 MB RAM
- supports only special 1 MB Nibble Mode SIMMs, they are more expensive than GVP SIMMs
- accepts SIMMs in groups of four
- 68030-RAM32: (from 1991)
- eight 64 pin SIMM sockets accept up to 8 or 20 MB RAM
- supports only special 1 or 4 MB, 60 ns GVP SIMMs
- 60 ns SIMMs are required for 50 MHz, 70 ns for 33 MHz, 80 ns for 25 MHz
- 16 - 33 MHz boards support 1 MB SIMMs only, possible configurations are 2, 4 and 8 MB
- 50 MHz boards support 4 MB SIMMs, possible configurations are 4, 8, 12, 16 and 20 MB
- using a 4 MB SIMM requires four 1 MB SIMMs to be installed in sockets 3 to 6, so the 4 MB SIMMs can only be installed into sockets 7 to 10
- optional IDE controller
- two autoboot ROM sockets
- to activate the IDE controller only the boot EPROM(s) (gvpat.device) has to be installed on the main board - the first version of the driver software required two EPROMs, later ones required only one
- does not support drives that has more than 1024 cylinders
- controller uses byte-swapped storaging, so the HDD will be unreadable on other controllers without that feature
- 40 pin internal IDE header
- A-Max II driver (gvpat.amhd) - requires gvpat.device v2.4 and A-Max v2.06
- notes
- autobooting requires at least Kickstart 1.3 - the autoboot ROM should not be installed with Kickstart 1.2
- two ROM sockets for UNIX boot ROMs that require an A2090A SCSI controller - these ROMs are compatible with those on the A2630
- 68000 fallback mode selectable by jumper
- the memory and IDE controller is also deactivated in fallback mode
- jumper settings - A3001
