Amiga Hardware DatabaseManufacturer Individual Computers, Germany | Date 2014 | Amiga A1200A2000, A3000, A4000 | - - | Interface clock portproprietary |
- USB interface
- provides two USB ports
- isp1763 USB host controller chip
- compatible to USB 1.1 and 2.0 specifications
- supports USB 2.0 highspeed mode (480 Mpbs)
- card features clock port and proprietary X-Surf 100 expansion connectors
- two expansion variants exist that differ with regard to the connection options and the scope of delivery:
- Clock Port Model
- both connectors active
- shipped with earthing cable, floppy power cable, plastic cover and bracket with two USB connectors
- more expensive than the other variant as the development effort was much higher due to the idiosyncrasies of the clock port
- X-Surf 100 Model
- clock port connector disabled, expansion is only usable on the X-Surf 100
- bare board with no protective cover or USB port bracket
- two floppy power connectors on the card to supply power to the USB ports - the second port can be used for the floppy, thus an Y cable is not needed
- this is only needed when used on a clock port (clock port doesn't provide enough power)
- if power hungry devices are used, it is also recommended when installed on the X-Surf
- supplies up to 1.5 ampere per USB port
- only supports PIO (Programmed I/O) operation (no DMA), thus having higher load on the CPU during transfers
- typical data rates: 7.5 MB/s (Zorro III), 2.5 MB/s (Zorro II), 700 kByte/s (Clock Port)
- notes
- when installed on the X-Surf, their external USB ports are activated - the internal ports of the RapidRoad can only be used if the respective external port stays empty
- white status LED on board indicates proper connection
- benefits from the faster secondary clock port on the A604n
- power on the USB ports is only switched on upon start of USB stack, this conformes to USB specification
- shipped with Poseidon 4.5 OEM USB stack
- requires at least 68020 processor, 2.5MB free FastRAM, MUI, OS3.0
- driver for e.g. USB mouse and keyboard (HID devices), mass storage, parallel interface (printers) and USB-serial bridges
