- Funny. I thought there was TCP/IP for the Amiga as well. Maybe I was
- dreaming last night when I thought I was using TCP/IP on Ethernet
- boards. I have alse been dreaming about ArcNet interface, DECNet
- software etc.. Real funny :-)

- I feel that a network interface that is slow _and_ allows a large number
- of computers to connect is not a good idea. It would be great to have an
- inexpensive network interface which could be used in classrooms, for
- example, to connect 20-30 A500's or A600's or A1200's to an A3000 acting
- as a file server. BUT if this network runs at, say, 115,000 bps (moves
- 11500 bytes/sec minus protocol overhead) and 20 ppl start loading DPaint..
- It would take over 10 minutes in the best case when no packets need to
- be retransmitted, much more in the worst case.
-
- One problem is that there's no good connector for this kind of an interface.
- The A500 has the expansion bus which could be used (unless it's already in
- use). THe A600 has a different, internal connector. The A1200 has yet
- another kind of bus. The PCMCIA slot could be used, probably with existing
- hardware (only software drivers would be needed) but the A500 doesn't have
- that port. I think the best way would be to use the PCMCIA port, anyway,
- and maybe build a PCMCIA interface for the A500. I am expecting that a
- standard network would be used, so you could get an Ethernet (or whatever)
- board for the fileserver (not needed when networking A600's at home).
-
- The disk connector could be used for some kind of a network but it would
- be pretty slow and very limited in all ways. It would also be a good way
- to burn the Paula chips of the machines.
