[comp.sys.masscomp] Better ethernet performance?

masscomp-request@soma.UUCP (04/22/87)

Does anyone know of alternatives to the Excelan board
for TCP/IP on a MC 5700?

We have bencmarked our machine and have found unacceptably
low performance across the network.  Our slow Sun-2 
(68010 @10Mhz) can out perform the supposed 5MIPS
Masscomp.  I suspect the problem is the 80186 processor
on the Excelan board is just not fast enough.

Anyone know how to use the "Lance" chip on a high
end Masscomp?

[MOD: To my knowledge, an alternative vendor is being considered, but
I am unaware of who it is or when it may be available. If you come to the
user group meeting next week, I am sure you can get the information you
need. I doubt that you can get a lance operation on the 5700 since the chip
is not on the CPU as it is on the 5300/5400/5500-PEP computers -- sob]

CMC has 68K-based ethernet boards which may me a little better than the Excelan.
One particular board has 68010 with 512K.  Our local rep is Gary Berkowitz (818)
884-2766 or their home office 805-936-9471.

We have not used it yet.  Thus I cannot comment on its performance.  We are in
the process of proccuring one.
