Manufacturer Ameristar Technologies, USA | Date 1988 | Amiga A2000, A3000, A4000 | Interface Zorro II | Autoconfig ID 1053 / 9 |
- Arcnet interface
- Arcnet networking system - old, slow but cheap and reliable, useful for small LANs and simple network sharing
- Arcnet requires RG62 coaxial cable instead of the RG58 used on Ethernet systems
- uses 93 ohm terminators opposed to the 50 ohm used by Ethernet
- the Arcnet interface hybrid chip comes in two different versions, HCY 9058 for bus networks and HCY 9068 for star networks
- interrupt driven (polled I/O) - one interrupt on the Amiga yields into a busy system
- two sockets for optional network autoboot ROMs
