X-Summary : 1. Do you have any personnal experience with VMEexec ?
	    2. Do you know any VMEexec software ftp server (or
		any other information medium) ?

Hi Folks,

I want to develop a data acquisition system for small-to-medium
sized nuclear physics experiments (1-100 detectors, 200 kb/s max data
throughput). The data will be read by VME processors from CAMAC, VXI
and VME modules and directly written on tape (ExaByte). In addition,
a sample of the data will go, through Ethernet, to UNIX/Ultrix
workstations (both SUN/DEC) for monitoring. One workstation will be
the master controller of the experiment and will send/receive requests
to/from the VME processors. A major requirement is that I want a VME crate
dedicated to the data acquisition task; that means that *I do not want
to see a UNIX (or others high level OS, with disks, screens, and ...)*
in this crate.

From the previous description, most of you will probably declare
that VxWorks is the solution I'm looking for ... but there are
problems, their support of DEC platforms and their licence policy :
VxWorks is too expensive for our budget.

Therefore, we have decided to look to another RTOS : VMEexec. We plan
to develop the software with their combined UNIX System V/68  - VMEexec
development system and then, when this will be finish, to move the VME
processors to the data acquisition crate. Therefore the targets
processors (MVME147 family) should be able to access the Ethernet
by themselves, without the UNIX SV/68 system. Is there any VMEexec
software support for that ? Will it be possible to boot the system
from the a SUN or DEC WorkStation on the net ?

Is there anybody having some personnal experiences with VMEexec ?
Do you know source of VMEexec software ? Do you know if there are
any support for non-Motorola CPU's available for VMEexec ?

Please send your answers to : Ninane@fynu.ucl.ac.be.
I will summarize.

Thanks a lot,
