We still keep a lot of CAMAC resources at KEKB and KEK-Linac, and 
we use 
  CC/Net from Toyo Japan
  ECC1365 from Hytec
  VSD2992 from Hytec

First two provide the direct Ethernet connections.  Since we had 
difficulties connecting from multiple unix hosts to ECC1365's, 
we limit accesses only from one host.  We have to run EPICS IOC/
Gateway on that unix host. 

Because of the above reasons, we also introduced CC/Net (when one 
of ECC1365 was broken).  It contains a standard PC inside the 
standard crate controller which should be situated in CAMAC 
stations 24 and 25.  If you need EPICS, you can run EPICS on it, 
as it runs standard Linux like FedoraCore or Debian.  If you need 
CAMAC performance, you can execute CAMAC transaction every 
micro-second (1.04 micro-sec).  Since the CAMAC cycle is one 
micro-second, it is almost the limit.  To my understanding the 
price is around $5000 or less. 

It was developed by the detector-online group at KEK, and several 
accelerator projects around KEK also employ it.  Some of the links 
are

(I realize that I don't provide any documents of CC/Net at my 
site...)

Cheers, Kazuro.
