Amiga Hardware DatabaseCompany Phoenix Microtechnologies, Australia | Date 1990 | Amiga A1000 | Autoconfig ID 2101 / 34 |
- replacement A1000 motherboard
- replaces the original A1000 motherboard
- includes all ports of the original A1000 motherboard
- adds a Zorro II and a video slot
- Paula, Denise, the CIAs and the 68000 have to be transfered from the old motherboard
- Agnus is not transfered, it is replaced by Fat Agnus
- ECS compatible
- Kickstart 1.3 preinstalled
- can hold four Kickstarts, two of which can be selected with the Kickstart Swap Switch
- two sockets for standard Commodore Kickstart ROMs
- four sockets for a set of up to 4×8 megabit EPROMs
- one socket for a 16 bit wide EPROM (8 megabit)
- internal RS232 serial header (same as on the A2000 motherboard)
- monochrome video output (RCA) instead of the A1000's composite colour output
- PGA FPU socket and oscillator socket
- disk drive swap switch - allows booting from a floppy disk drive other than DF0:
- software switching of the 7.5 kHz audio filter - disabling the filter dramatically improves sound quality
- battery backed up clock
- all chips are socketed
- memory on motherboard
- 16 DIP sockets accept up to 2 MB RAM
- accepts 256k×4 DIPs in groups of four
- possible configurations:
- 512 kB Chip RAM
- 512 kB Chip + 512 kB Fast RAM
- 1 MB Chip RAM
- 1 MB Chip + 1 MB Fast RAM
- 2 MB Chip RAM (requires Super Agnus to be installed)
- optional memory daughterboard (
- 16 ZIP sockets for 8 MB RAM
- takes 1M×4 ZIPs
- connects into the 96 pin DIN connector
)
- SCSI controller
- autoboot ROM
- 5380 controller IC
- 50 pin internal SCSI header
- optional DB25 external connector kit
- optional internal hard disk mounting kit
- SCSI-Direct support
- does not support the RDB standard
- on revision I motherboards a hardware interrupt logic is implemented
- allows the SCSI subsystem to work with disconnect/reconnect and diskchange interrupts
- provides better compatibility with SCSI2 hardware and CD-ROMs
- increases performance of non-HD devices
- A-Max driver
- optional genlock clock module
- with a 2 MB ECS Agnus genlocks are not supported without this module
