Company RBM Digitaltechnik, Germany | Date 1997 | Amiga A1200 | Interface trapdoor slot |
- Zorro busboard
- 5× Zorro II slots
- does not support DMA - many SCSI cards are ruled out
- does not comply with the Zorro II specifications:
- /XRDY (External Ready - used for adding wait states) is halfways implemented
- /OVR (/DTACK Override - used for delaying Zorro bus cycle termination) is not implemented at all
- as a side effect it is possible to achieve 2-cycle Zorro accesses - faster than other Zorro boards if the card can take advantage of it
- optional extended video slot - VidiON ex module
- a Zorro III upgrade with A4000 style CPU slot (TurboON 32) was planned but never realised
- connects to the trapdoor slot - the connector is passed through for accelerator cards
- the board is part of the RBM Towerhawk 1200 IIex tower system
