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
jumper settings
- rev 3
