It works between two Amigas and will probably work between : three. Beyond that I have no idea what the bus drivers have enough : guts. Any chance you can elaborate on how the cabling would be done for three Amigas? I'm running NET: via the parallel port between the 2000 and 3000, but I'd sure like to hook the 1000 in also... It's wonderful to be able to use any HD partition on any machine. :-) Normally, you just jumper between select and acknowledge for two machines. No need for some sort of token ring on three machines? Just look at all the packets and only intercept those that are supposed to be talking to you? If I can just jumper the three machines together and add in a UNIT=2 to one, I'll be happy! :-) : -Matt : :-- : : : Matthew Dillon dillon@Overload.Berkeley.CA.US : 891 Regal Rd. uunet.uu.net!overload!dillon : Berkeley, Ca. 94708 : USA -- -Bill Seymour ...tektronix!reed!percival!agora!billsey ============================================================================= Bejed, Inc.
