Amiga Hardware DatabaseCompany Kupke, Germany | Date 1991 | Amiga A1000 | Interface side expansion port |
- processor
- 68030 @ 14 MHz (synchronous with the A1000)
- optional FPU - it can either run at 14 MHz, or use a separate crystal up to 50 MHz
- memory
- 32 DIP sockets accept up to 16 MB RAM
- supports 256k×4 (514256) or 1M×4 (514400) DIPs, 80 ns or faster
- accepts DIPs in groups of eight
- notes
- connects to the side expansion port
- passthrough connector - has mechanical problems with expansions whose plug is thicker than 9.5 mm
- 68000 fallback mode (also disables the memory expansion)
- has problems with old hard disk systems without any kind of handshake (either hardware or software handshake) - most of the RLL/MFM controllers (e.g. OMTI) do not work
- does not work with some old hardware like memory expansions or clock modules - they need a modification
- jumper settings
