We are planning to purchase an ADA package for writing
real-time application for 68020 target processors. 
We would like to compile our programs on SUN4 to speed up
compilation time.  Naturally we require a cross compiler to
convert over to the 68020 targets.

We are considering 3 packages: Alsys, Verdix, and Telesoft.
My understanding is that Verdix has the worst reputation among these 3.
Do you agree?  Can anyone tell me the pros and cons about these
companies?

We want to request from Alsys a trial version.  Only problem is
that they do not have a SUN4 version.  They say that a SUN4 version
will be available in the early part of 1991 -- I am not sure
whether it will have all the features that their SUN3 version have.
How good are their products?

We have also requested from Verdix.  They have a SUN4 version now,
so we are going to get this one.  Only concern is, for us to
make any meaning comparions (features, speed, etc), we would
like to get the SUN3 version of Verdix to compare with
Alsys's.  But we decided saving compiling time is more important
and that we want to try out the SUN4 version that we are actually
buying, rather than believe on faith that the yet-to-be
released version of Alsys's SUN4 version will be just as good 
as their SUN3 version.

We are not sure whether we want to buy Telesoft's, because theirs
cost $50,000 which is $20K more than those of Alsys and Verdix.

We would like to get any comments on this matter.
