We need to get some Ethernet controllers for some 68K/VERSAbus systems we have. Does anyone have experience with such a beast? (Another possibility we are considering is using a Multibus controller through a Multibus/VERSAbus adapter.) If you know of something we can use, please reply by mail, and I'll summarize to the net if there is interest.

#R:tymix:-21100:uiuccsb:8800002:000:699 uiuccsb!johnston Apr 5 10:14:00 1984 There are two companies that we know of that make Ethernet controllers for VERSAbus: 1. Communication Machinery Corporation 1226 Anacapa Santa Barbara, CA 93101 (805) 963-9679 Their model is the ENP-20 which incorporates on-board RAM (32k bytes, I think), DMA control, and utilizes the AMD LANCE/SIA (Am7990/AM7991). It is pretty "intelligent" due to the LANCE. See the LANCE/SIA data from AMD. 2. Associated Computer Consultants 720 Santa Barbara Street Santa Barbara, CA 93101 (805) 963-9431 Their model is the V/EIU (VERSAbus/Ethernet Interface Unit. Not as sophisticated as the above, but not as expensive either. Also they have a lot of software support available and planned.

I came in on this discussion late, but... Motorola also makes an Ethernet controller for Versabus, the M68KVM33. It also uses the AM7990 LANCE and AM7991 SIO. It has XNS software, and supposedly runs at 200 1K-byte packets per second (Motorola figure). w underwood
